Static routes set by system.inc for DNS gateway bindings are not binded on the good NICs
0%
Description
Hello,
We are running a POC with 2 WAN gateways which use their own DNS servers on a per-FAI basis.
The 2 gateways are using 2 different NIC (bge0 and bge2).
Though, we get these 4 IP routes, with the first 2 routes which should use -iface bge2 instead, according to gateways configurations:
80.10.246.130 172.1.6.2 UGHS bge0 81.253.149.1 172.1.6.2 UGHS bge0 89.2.0.1 172.1.6.1 UGHS bge0 89.2.0.2 172.1.6.1 UGHS bge0
If I understand correctly, these lines are created here: https://github.com/pfsense/pfsense/blob/master/src/etc/inc/system.inc#L196.
The gateway affected by this issue is using an interface in DHCP mode (the FAI box acts as a DHCP server), and we can see "dynamic" in the "Gateway" field of the Gateway.
Any idea to solve this issue?
Thanks.

Hello,
I discovered that this behaviour was related to the current settings, with 2 gateways on the same subnet, so it overlaps...
Everything works as expected with a fixed setup, but I'm leaving this ticket opened for now, as it might be a good thing to specify the NIC on the route command, as it's done in other places of the pfSense code. Any feelings?
Thanks.

Doesn't matter what you choose for the interface, overlapping subnets and duplicate gateways are not supported.
