Our offices are out in the sticks and I am having trouble getting two subnets to talk to each other (I am ok with really basic networking but I get stumped when things like this don’t work as I expected). As the 4th subnet that is connected via pfsense is working fine, I have proved that it is possible so just need to know where I am going wrong with the RUTX09 configuration.
AWS (wireguard 10.100.10.1) used to bridge networks together as its the only point with a fixed IP.
Teltonika RUTX50 in main office 10.10.10.1 (Wireguard 10.100.10.100).
Teltonixa RUTX11 in remote office 10.11.10.1 (Wireguard 10.100.10.101).
Teltonika RUTX09 near main office 10.30.10.1 port 3 set to 10.10.10.5 and connected to main office LAN.
PFSense near main office 10.20.1.1 port X set to 10.10.10.4 and connected to main office LAN.
10.10.10.X can talk to 10.11.10.X.
10.20.10.X can talk to 10.11.10.X (10.10.10.1 has a static route 10.11.10.0 to 10.10.10.0).
10.30.10.X will not talk to 10.11.10.X.
10.20.10.X can talk to 10.10.10.X.
10.30.10.X can talk to 10.10.10.X.
I have tried adding a static route for 10.11.10.X to gateway 10.10.10.1 like pfsense has (I did this), on the RUTX09.
I noticed that pfsense has an entry in NAT that it has made automatically for 10.11.10.1.
I don’t see any way of adding NAT to a subnet that isn’t associated to a LAN interface on the Teltonika units and suspect that is the problem.
I have gotten around it by also setting up wireguard on the RUTX09 but I would prefer it to work through the one link like 10.30.10.X does on pfsense.
Can anyone help me with this please?
