CT100 now routes 192.168.42.0/24 for the personal group, letting
Mac/iPhone reach LAN devices that don't run NetBird (OpenWrt,
Proxmox nodes, NAS, printers, cameras, etc).
- IP forwarding persisted via /etc/sysctl.d/99-netbird-route.conf
- Route created with masquerade=true, metric=9999
- access_control_groups restricts who can use the route
- Chose CT100 over CT124 to avoid the Tailscale kernel-mode
iptables collision documented in peer-deployment-ops.md
Doc covers: concept, API + UI creation, verification, troubleshooting
(forwarding, masquerade, LXC caveats, Tailscale interference),
and security considerations for narrowing the route CIDR.
