This Skill helps diagnose and resolve complex routing problems on Linux systems using NetBird, particularly when traffic fails to reach remote subnets or experiences asymmetric routing.
Use the routing-troubleshooting skill to diagnose why a host is reachable via LAN but not from a remote subnet routed through a gateway.

Asymmetric routing on Linux often causes ping to succeed while TCP fails. NetBird's policy routing table 7120 can route return traffic incorrectly, dropping TCP state. Diagnose the flow using the `ip` command to inspect routing rules and apply static route overrides to fix it.
Troubleshoot NetBird routing by checking policy routing table 7120 for unexpected subnets or stale routes from removed peers. Use the `ip` command to verify route paths and `systemctl` to restart the NetBird service, clearing outdated network state.
Remove stale NetBird routes by inspecting policy routing table 7120 with the `ip` command to identify outdated subnets. Flush the incorrect routes and restart the NetBird service via `systemctl` to ensure the routing table only contains active peer networks.
NetBird policy routing table 7120 is a Linux routing table managing traffic for remote subnets. Inspect it when you experience asymmetric routing or unexpected subnet behavior, using the `ip` command to verify if static route overrides are needed to correct traffic flow.
Yes, you can implement static route overrides on Linux to correct asymmetric routing caused by NetBird. By configuring static routes, you ensure traffic flows through specific interfaces correctly, bypassing conflicting policy routing table 7120 entries.
Yes, diagnosing NetBird routing issues requires the `ip` command for checking policy routing tables and interface paths, and `systemctl` for restarting the NetBird service to apply route changes or clear stale peer entries.
