DNS A records now return the WireGuard server IP (10.0.0.1) instead of
Docker bridge VIPs so cross-cell peers resolve service names correctly
regardless of their bridge subnet. DNAT rules (wg0:53→cell-dns:53 and
wg0:80→cell-caddy:80) are applied at startup. Caddy routes by Host header,
eliminating the Docker bridge subnet conflict. Firewall cell rules allow
DNS and service (Caddy) traffic from linked cell subnets. Split-tunnel
AllowedIPs now dynamically includes connected-cell VPN subnets and drops
the 172.20.0.0/16 range. Peers with route_via set now receive full-tunnel
config (0.0.0.0/0) so all their traffic exits via the remote cell.

The PostUp rule appended `iptables -A FORWARD -i wg0 -j ACCEPT` which
allowed any WireGuard-connected client full internet access regardless of
per-peer rules, even when no peers were configured in wg0.conf.
Fix: change PostUp/PostDown to use DROP as the catch-all. Per-peer and
per-cell rules use -I (insert at top) so they take precedence; unknown
or unconfigured WG traffic hits the DROP at the bottom.
Also add reconcile_stale_peer_rules() called on startup to remove FORWARD
rules for peer IPs that no longer exist in the registry, preventing deleted
peers from retaining firewall access across container restarts.

Adds the ability to route a specific peer's internet traffic through a
connected cell acting as an exit relay.
Cell A side:
- PUT /api/peers/<peer>/route-via {"via_cell": "cellB"} sets route_via
- Updates WG AllowedIPs to include 0.0.0.0/0 for the exit cell peer
- Adds ip rule + ip route in policy table inside cell-wireguard so the
specific peer's traffic egresses via cellB's WG IP
- Sets exit_relay_active on the cell link and pushes use_as_exit_relay=True
to cellB via peer-sync
Cell B side:
- Receives use_as_exit_relay in the peer-sync payload
- Calls apply_cell_rules(..., exit_relay=True) to add FORWARD -o eth0 ACCEPT
- Stores remote_exit_relay_active flag for startup recovery
Startup recovery:
- apply_all_cell_rules passes exit_relay=remote_exit_relay_active (cellB)
- _apply_startup_enforcement reapplies ip rule for each peer with route_via (cellA)
since policy routing rules don't survive container restart
peer_registry gets route_via field with lazy migration.
22 new tests across test_cell_link_manager, test_peer_registry, test_peer_route_via.

wg set updates WireGuard peer state but does not add kernel routes —
unlike wg-quick. Without ip route add, traffic to a remote cell's
vpn_subnet is routed via the default gateway (internet) instead of wg0,
causing all cross-cell pushes to time out with HTTP 000.
- add_cell_peer() now calls _ensure_cell_route(vpn_subnet) after
writing the peer config and running _syncconf
- _ensure_cell_route() runs docker exec cell-wireguard ip route add
(idempotent, non-fatal); no-op inside test dirs
- sync_cell_routes() parses wg0.conf at startup to re-add any routes
lost across container restarts; called from _apply_startup_enforcement
- 5 new unit tests covering both normal and test-dir no-op paths

Phase 1 — connection fixes:
- routing_manager.stop(): remove iptables -F / -t nat -F nuclear flush that
would wipe WireGuard MASQUERADE and all peer rules on any UI stop action
- wireguard_manager.add_cell_peer(): reject vpn_subnet that overlaps the local
WG network (routing blackhole — was the root cause of no handshake)
- wireguard_manager._syncconf(): pass Endpoint to 'wg set' so cell peers with
static endpoints are synced to the kernel (not just AllowedIPs)
Phase 2 — service-sharing permissions backend:
- firewall_manager: add _cell_tag(), clear_cell_rules(), apply_cell_rules(),
apply_all_cell_rules() — iptables FORWARD rules for cell-to-cell traffic
using 'pic-cell-<name>' comment tags, distinct from 'pic-peer-*'
- app.py startup enforcement: call apply_all_cell_rules(cell_links) so rules
survive API restarts
- cell_link_manager: permissions schema {inbound, outbound} per service;
lazy migration for existing entries; update_permissions(), get_permissions();
apply_cell_rules wired into add_connection/remove_connection
- routes/cells.py: GET /api/cells/services, GET+PUT /api/cells/<n>/permissions;
RuntimeError now returns 400 (not 500) from add_connection
Removed broken 'test' cell (subnet 10.0.0.0/24 collided with local WG network).
Second PIC must use a distinct subnet (e.g. 10.0.1.0/24) before reconnecting.

linuxserver/wireguard auto-generates its own PrivateKey on first container
start, independently of the PIC API's key-store. When the two diverge, the
API generates peer configs with the wrong server public key and the WireGuard
handshake fails silently — the client can ping the VPN subnet (10.0.0.x) but
gets no internet and cannot reach any Docker service (172.20.0.x).
Adds _sync_keys_from_conf(): called at the top of apply_config(), reads the
PrivateKey from wg0.conf, derives the matching public key, and overwrites the
API key files (private.key / public.key) if they differ. This makes wg0.conf
the authoritative source for the server identity, keeping get_peer_config()
consistent with the live WireGuard interface.
Adds 5 new tests in TestSyncKeysFromConf covering:
- key-store update when conf key differs
- no-op when keys already match
- get_peer_config() uses the synced key
- no raise when conf is missing
- apply_config() passes the synced key through bootstrap

apply_config() now calls _load_registered_peers() when wg0.conf is empty
so all active peers from peers.json are written back into the config file
after a bootstrap — preventing clients from losing tunnel access after
an API restart that regenerated wg0.conf from scratch.
Adds test_wireguard_vpn_routing.py (36 tests) covering:
- generate_config() PostUp/PostDown rules enabling internet forwarding
(MASQUERADE + FORWARD ACCEPT required for internet-through-VPN)
- get_peer_config() DNS field pointing to cell-dns for domain resolution
- apply_config() bootstrap peer restoration from peers.json
- _load_registered_peers() filtering (inactive, missing fields, malformed)
- add_peer() /32 AllowedIPs enforcement to prevent route leaks

If wg0.conf exists but is empty or has no [Interface] section,
apply_config previously found no lines to update and silently
returned with no changes — leaving the container broken on next
restart with an empty config.
Fix: detect empty/missing [Interface] section and regenerate the
full config from generate_config() before applying field updates.
This was the root cause of port changes not propagating:
apply_config was called but found nothing to patch in an empty file.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Bug 1 — port not propagated to wg0.conf:
The identity update path (wireguard_port via PUT /api/config) was calling
wireguard_manager.update_config() which only saves to a JSON file via
BaseServiceManager. wg0.conf was never updated, so after a container
restart the WireGuard interface would still listen on the old port.
Fix: call apply_config() instead — it writes ListenPort into wg0.conf.
Bug 2 — check_port_open ignored configured port:
check_port_open() checked for 'listening port' in wg show output but
never compared it against the configured port. A port-mismatch (e.g.
after config change but before restart) would return True — misleading.
Fix: require 'listening port: {configured_port}' to match exactly.
Tests added:
- test_check_port_open_wrong_port_returns_false
- test_check_port_open_explicit_port_matches
- test_check_port_open_explicit_port_mismatch
- test_wireguard_port_identity_change_calls_apply_config
- test_wireguard_port_same_value_does_not_call_apply_config

Root cause: sysctl -q net.ipv4.conf.all.rp_filter=0 in PostUp exited non-zero
inside the linuxserver/wireguard container (no permission), causing wg-quick to
tear down the wg0 interface — breaking peer status, port check, and internet
access through full tunnel.
- wireguard_manager.py: add || true to both sysctl PostUp/PostDown lines
- docker-compose.yml: add net.ipv4.conf.all.rp_filter=0 to wireguard sysctls
- WireGuard.jsx: kick off port check asynchronously on page load (was refresh-only)
- tests: add TestWireGuardSysctlAndPortCheck — 14 new tests covering sysctl
content, check_port_open (interface up / down / fallback-to-handshake),
get_peer_status (online / offline / not-found / no-handshake), and
get_all_peer_statuses (multi-peer / empty / skips interface line)

Two bugs fixed:
1. calendar_manager and wireguard_manager (port-only) called
_restart_container immediately in apply_config, bypassing the pending
restart banner and restarting the container before the docker port
binding in .env was updated — leaving the service broken until the
banner was applied manually. apply_config now only updates the config
file (radicale.conf / wg0.conf); the docker compose restart happens
via the banner as intended.
2. Port change detection in update_config used `if old_val is not None`
to guard against triggering on unchanged values. When a service's port
was never explicitly saved (first time), old_val was None, so the
pending restart was never queued. Fix: fall back to PORT_DEFAULTS[key]
so the comparison is always against the effective current value.
Add TestPortChangeDetection (5 tests) covering first-save and multi-service
accumulation cases.

- app.py: ConfigManager now uses CONFIG_DIR env var for config file path
instead of hardcoded './config/cell_config.json' — config was being read
from the image's working directory, making all settings writes ephemeral
(lost on container restart)
- wireguard_manager: generate_config uses configured address/port instead of
hardcoded 10.0.0.1 in DNAT rules and Address field
- scripts/setup_cell.py: full setup script — generates WireGuard keys (wg
binary or Python cryptography fallback), writes wg0.conf and cell_config.json
with correct _identity key; CELL_NAME / VPN_ADDRESS / WG_PORT env vars
- Makefile: setup target passes env vars through; build-api / build-webui targets
- README: replace install.sh references with make setup && make start

Site-to-site WireGuard tunnels between PIC cells with automatic DNS forwarding.
Each cell generates an invite JSON (public key, endpoint, VPN subnet, DNS IP,
domain); the remote cell imports it to establish a bidirectional tunnel and
CoreDNS forwarding block so each cell's domain resolves across the mesh.
Backend:
- CellLinkManager: invite generation, add/remove connections, live WireGuard
handshake status; stores links in data/cell_links.json
- WireGuardManager: add_cell_peer() accepts subnet CIDRs (not /32) and an
optional endpoint for site-to-site peers; _read_iface_field() reads port,
address, and network directly from wg0.conf at runtime instead of constants
- NetworkManager: add/remove CoreDNS forwarding blocks per remote cell domain
- app.py: /api/cells/* routes; _next_peer_ip() derives VPN range from
configured address so peer allocation follows any address change
Frontend:
- CellNetwork page: invite panel (JSON + QR), connect form (paste JSON),
connected cells list (green/red status, disconnect button)
- App.jsx: Cell Network nav entry and route
Tests: 25 new tests across test_wireguard_manager, test_network_manager,
test_cell_link_manager (263 total)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Backend:
- wireguard_manager: _get_configured_port/address/network() read from wg0.conf
instead of module-level constants; get_split_tunnel_ips() derives VPN network
from configured Address; get_server_config() returns configured port, dns_ip,
split_tunnel_ips, vpn_network
- add_peer() and get_peer_config() use configured port (not hardcoded 51820)
- _next_peer_ip() derives subnet from wireguard_manager._get_configured_address()
so new peers are allocated IPs from the correct VPN range after address change
- refresh-ip and check-port API endpoints return configured port, not 51820
- PUT /api/config: when wireguard port/address changes, all peers are marked
config_needs_reinstall so users know to re-download tunnel configs
- get_peer_config endpoint: uses configured split tunnel IPs (not hardcoded)
Frontend:
- Peers.jsx: SERVICES domains use live domain from ConfigContext; generateConfig()
uses serverConf.dns_ip and serverConf.split_tunnel_ips; vpn_network shown in
peer-access description; DNS hint uses live domain; server config loaded at
mount time so it is available without re-fetching on every peer action;
handleUpdatePeer uses /32 for server-side AllowedIPs (was incorrectly using
full/split tunnel CIDRs which the backend rejects)
- WireGuard.jsx: generateWireGuardConfig() uses serverConfig.dns_ip,
split_tunnel_ips from server-config API; split-tunnel description shows
live IPs
Tests: 9 new tests in TestWireGuardConfigReads verify all config reads

Each service manager now has apply_config() that writes to the actual config:
- network: dhcp_range → dnsmasq.conf (reload cell-dhcp), ntp_servers → chrony.conf
(restart cell-ntp), domain → dnsmasq.conf domain= line
- email: domain → mailserver.env OVERRIDE_HOSTNAME + POSTMASTER_ADDRESS,
restart cell-mail
- wireguard: port/address/private_key → wg0.conf ListenPort/Address/PrivateKey,
restart cell-wireguard
- calendar: port → radicale config hosts=, restart cell-radicale
PUT /api/config now calls apply_config() after persisting JSON, and returns
{restarted: [...], warnings: [...]} so Settings UI can show which containers
were restarted. _restart_container() helper added to BaseServiceManager.

Service manager fixes (connectivity tests):
- email_manager: replace telnet with socket.create_connection for SMTP/IMAP;
replace nslookup with socket.getaddrinfo for DNS; exclude unconfigured domain
from success (email healthy=False now correctly means ports refused, not missing domain)
- calendar_manager: replace localhost:5232 with cell-radicale:5232;
fix database check to test dir writability instead of file existence (files created on demand)
- file_manager: replace localhost:8080 with cell-webdav:80; add top-level success key
- network_manager: replace nslookup with socket.getaddrinfo;
add success key to dhcp_test and ntp_test return values
- routing_manager: exclude iptables_access from success
(iptables runs in cell-wireguard, not API container)
- wireguard_manager: add success key to no-arg test_connectivity result
Health history UI:
- SvcCol reads data?.status?.running || data?.status?.status — handles nested health check shape
Result: network/wireguard/calendar/files/routing/vault all healthy=True.
Email healthy=False is correct — mail server needs ≥1 account before Dovecot starts.

docker-compose.yml:
- Add json-file logging driver (max-size: 10m, max-file: 5) to all 13 containers
- Docker now owns container stdout/stderr rotation automatically
- Add ./data/logs:/app/api/data/logs volume to API — service logs now persist across restarts
log_manager.py:
- Remove container log collection hack (Docker handles it natively)
- Add set_service_level(service, level) — change log level at runtime without restart
- Add get_service_levels() — return current per-service levels
- Simplify get_all_log_file_infos to return only service log files
app.py:
- Add GET /api/logs/verbosity — return current per-service log levels
- Add PUT /api/logs/verbosity — update levels at runtime, persist to config/log_levels.json
- Load persisted log level overrides at startup from log_levels.json
- Simplify rotate endpoint (service logs only, container logs owned by Docker)
wireguard_manager.py:
- get_keys(): return empty strings if key files don't exist (prevents get_status crash
when wg0.conf is missing at startup and falls through to generate_config)
Logs page (4 tabs):
- API Service Logs: structured JSON logs from Python managers, with search/filter/rotate panel
- Container Logs: live docker logs (read via existing /api/containers/<name>/logs endpoint)
- Verbosity Config: per-service level dropdowns, apply immediately + persist
- Health History: existing health poll table
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- WireGuardManager.test_connectivity: make peer_ip optional so health_check
can call it without args (was logging ERROR on every health poll)
- Logs page: add ALL option to service selector (uses search across all services)
- Logs page: show service tag on each log line when in ALL/search mode
- Logs page: require window.confirm before rotating logs to prevent accidental data loss

Added a path guard: if the config file resolves to /tmp/ or a pytest
temp dir, _syncconf bails out immediately. Without this, tests calling
add_peer/remove_peer with a temp-dir WireGuardManager would connect to
the live cell-wireguard container and remove production peers.

Server-side access control:
- firewall_manager.py: per-peer iptables FORWARD rules in WireGuard container;
virtual IPs on Caddy (172.20.0.21-24) for per-service DROP/ACCEPT targeting
- CoreDNS Corefile regenerated with ACL blocks for blocked services per peer
- POST /api/wireguard/apply-enforcement re-applies rules after WireGuard restart;
wg0.conf PostUp calls it via curl so rules restore automatically on container start
WireGuard fixes:
- _syncconf uses `wg set peer` instead of `wg syncconf` to avoid resetting ListenPort
- add_peer validates AllowedIPs must be /32 — rejects full/split tunnel CIDRs that
would route internet or LAN traffic to that peer
- _config_file() checks for linuxserver wg_confs/ subdirectory first
UI:
- Peers page fetches /api/wireguard/peers/statuses for live handshake data;
status badge now shows real Online/Offline + seconds since last handshake
- IP field removed from Add Peer form (auto-assigned from 10.0.0.0/24)
Tests (246 pass):
- test_firewall_manager.py: 22 tests for ACL generation, iptables rule correctness,
comment tagging, clear_peer_rules filter logic
- test_peer_wg_integration.py: 10 tests for /32 enforcement, IP auto-assignment,
syncconf called on add/remove
- test_wireguard_manager.py: updated to reflect correct IPs and /32 requirement
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- WireGuard default changed to full tunnel (0.0.0.0/0) — all peer traffic
routes through PIC server so internet latency matches server's clean 41ms
- UI tunnel toggle now defaults to Full tunnel
- API /peers/config accepts allowed_ips param so UI toggle wires through
- Routing page reads real host routes via /proc/1/net/route (pid: host)
instead of mock data; shows ens18/192.168.31.1 correctly
- Add iproute2 + util-linux to API Dockerfile

wg show outputs "listening port" not "listen port" — substring mismatch
caused port status to always show Blocked. Add webdav.cell, webmail.cell,
api.cell to Caddyfile and cell.zone so VPN peers can reach all services.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Assign static IPs to all 13 containers (172.20.0.2–13) so DNS zone
records match actual container IPs regardless of start order.
- Update cell.zone: all .cell domains now point to cell-caddy (172.20.0.2)
which is the correct single entry point via Caddy reverse proxy.
- Create config/radicale/config so the calendar container actually starts.
- Fix webdav: replace empty users.passwd with USERNAME/PASSWORD env vars.
- Fix DNS fallback IP in wireguard_manager: 172.20.0.2→172.20.0.3 (cell-dns).
- Remove duplicate http://ui.cell from Caddyfile.
- Add persistent data volumes for rainloop and filegator.
- Fix mail domainname placeholder (yourdomain.com→cell.local).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- check_port_open now checks if wg0 interface is actually listening (via
'wg show wg0') instead of requiring a live peer handshake. This means
the port shows 'Open' whenever WireGuard is running, not only when a
peer has connected recently.
- get_peer_config defaults to split-tunnel AllowedIPs (10.0.0.0/24,
172.20.0.0/16) so VPN clients only route cell service traffic through
the tunnel. Local LAN traffic (192.168.x.x etc.) stays direct, fixing
the 60-120ms penalty when pinging local hosts while on VPN.
- Peer config modal now uses cell DNS (172.20.0.2) so .cell domains
resolve correctly with both split and full tunnel.
- Added split/full tunnel toggle in the peer config modal so users can
download either config variant.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
When a full-tunnel VPN client pings the server's own public IP, traffic
loops out through Docker's external interface and back, causing 60-120ms
jitter. The DNAT PostUp rule intercepts packets from wg0 destined for the
public IP and redirects them to 10.0.0.1 (the VPN interface), keeping
traffic entirely inside the tunnel.
Also updates SERVER_ADDRESS from 172.20.0.1/16 to 10.0.0.1/24 to avoid
routing conflict with the Docker bridge network on eth0.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Fix CoreDNS not loading .cell zones (wrong Corefile path, now uses -conf flag)
- Fix WireGuard server address conflict (172.20.0.1/16 overlapped with Docker
network; changed to 10.0.0.1/24 to eliminate duplicate routes)
- Add SERVERMODE=true and sysctls to WireGuard docker-compose for server mode
- Fix DNS zone file parser to handle 4-field records (name IN type value)
- Add get_dns_records() to NetworkManager; mount data/dns into API container
- Fix peer config endpoint: look up IP/key from registry, use real endpoint
- Add bulk peer statuses endpoint keyed by public_key
- Normalize snake_case API fields to camelCase in WireGuard UI
- Add port check endpoint (checks via live handshake, not unreliable TCP probe)
- Add Caddy virtual hosts for ui/calendar/files/mail .cell domains (HTTP only)
- Fix cell config domain default from cell.local to cell
- Fix Routing Network Config tab (was calling hardcoded localhost:3000)
- Fix DNS records display (record.value not record.ip)
- Move service access guide to top of Dashboard with login hints
- Add /api/routing/setup endpoint
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- WireGuardManager: get_external_ip() (cached 1h), check_port_open(),
get_server_config() returning public_key + detected endpoint
- API: /api/wireguard/server-config returns real external IP;
/api/wireguard/refresh-ip forces re-detection;
/api/wireguard/peers/config now looks up peer IP + private key from
registry and uses real server endpoint automatically
- Fix doubled port in Endpoint (178.x:51820:51820 → 178.x:51820)
- Fix Address=/32 when peer_ip already has mask
- WebUI nginx: proxy /api/ and /health to cell-api (fixes localhost:3000
hardcode — UI now works from any machine)
- api.js: baseURL='' so all calls go through nginx proxy
- WireGuard page: show Server Endpoint card with external IP, endpoint,
public key, and Refresh IP button
