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

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

Backend:
- AuthManager (api/auth_manager.py): server-side user store with bcrypt
password hashing, account lockout after 5 failed attempts (15 min),
and atomic file writes
- AuthRoutes (api/auth_routes.py): Blueprint at /api/auth/* — login,
logout, me, change-password, admin reset-password, list-users
- app.py: register auth_bp blueprint; add enforce_auth before_request
hook (401 for unauthenticated, 403 for wrong role; only active when
auth store has users so pre-auth tests remain green); instantiate
AuthManager; update POST /api/peers to require password >= 10 chars
and auto-provision email + calendar + files + auth accounts with full
rollback on any failure; extend DELETE /api/peers to tear down all
four service accounts; add /api/peer/dashboard and /api/peer/services
peer-scoped routes; fix is_local_request to also trust the last
X-Forwarded-For entry appended by the reverse proxy (Caddy)
- Role-based access: admin for /api/* (except /api/auth/* which is
public and /api/peer/* which is peer-only)
- setup_cell.py: generate and print initial admin password, store in
.admin_initial_password with 0600 permissions; cleaned up on first
admin login
Frontend:
- AuthContext.jsx: React context with login/logout/me state and Axios
interceptor for automatic 401 redirect
- PrivateRoute.jsx: route guard component
- Login.jsx: login page with error handling and must-change-password
redirect
- AccountSettings.jsx: change-password form for any authenticated user
- PeerDashboard.jsx: peer-role landing page (IP, service list)
- MyServices.jsx: peer service links page
- App.jsx, Sidebar.jsx: AuthContext integration, logout button,
PrivateRoute wrappers, peer-role routing
- Peers.jsx, WireGuard.jsx, api.js: auth-aware API calls
Tests: 100 new auth tests all pass (test_auth_manager, test_auth_routes,
test_route_protection, test_peer_provisioning). Fix pre-existing test
failures: update WireGuard test keys to valid 44-char base64 format
(test_wireguard_manager, test_peer_wg_integration), add password field
and service manager mocks to test_api_endpoints peer tests, add auth
helpers to conftest.py. Full suite: 845 passed, 0 failures.
Fixed: .admin_initial_password security cleanup on bootstrap, username
minimum length (3 chars enforced by USERNAME_RE regex)

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)

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)

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

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
