I have “fallen” on an interesting issue related to static routes. The same issue occurs both in stock XT8 software and 3004.388.8_4-gnuton1.
What I am trying to do is add a static route to a router connected to VLAN 503 on Guest Network 1.
If I add a static route using the web gui to an IP address on the “Non Guest” part of the router (say 192.168.48.4) then every thing works normally. A route is created in the gui and a matching entry created in the route table. If however I point a static route at a device in the guest 1 network (in this case 192.168.103.250) the route appears to be created in the gui (see attached) however looking at route -n no route is actually created and a bunch of the following error is generated.
Jun 2 06:54:07 kernel: ^[[0;33;41m[ERROR mcast] bcm_mcast_netlink_process_snoop_cfg,1015: interface 24 could not be found^[[0m
Jun 2 06:54:07 kernel: ^[[0;33;41m[ERROR mcast] bcm_mcast_netlink_process_snoop_cfg,1015: interface 24 could not be found^[[0m
Jun 2 06:54:07 kernel: ^[[0;33;41m[ERROR mcast] bcm_mcast_netlink_process_snoop_cfg,1015: interface 24 could not be found^[[0m
If however, I delete the static route from the gui and add it via ssh with:
ip route add 192.168.20.0/24 via 192.168.103.250
The route is created correctly and everything works correctly. As expected the web gui is “unaware” of this route (even though it works just fine).
Here is a snippet from the route table (route -n) (note the 81.0 subnet is created by OpenVPN):
192.168.20.0 192.168.103.250 255.255.255.0 UG 0 0 0 br3
192.168.48.0 0.0.0.0 255.255.252.0 U 0 0 0 br0
192.168.81.0 0.0.0.0 255.255.255.0 U 0 0 0 tun21
192.168.102.0 0.0.0.0 255.255.255.0 U 0 0 0 br2
192.168.103.0 0.0.0.0 255.255.255.0 U 0 0 0 br3
It appears that the gui is getting “confused” when it tries to create the route however the rest of the system is “happy”.
Any thoughts appreciated.
