local/static routing issue - any help would be appreciated

[tdalej]

This is the page from OPNSense docs: https://docs.opnsense.org/manual/routes.html
Short and sweet, but not much help.

I had a LAN configured between two other somewhat similar firewall products.
Site 1 LAN 192.168.10.0/24
Site 1 LAN for interconnect 192.168.30/0  (Interface 192.168.30.1)

Site 2 LAN for interconnect 192.168.30/0  (Interface 192.168.30.2)
Site 2 LAN 192.168.20.0/24

Site 1 Gateway for route to site 2 -  192.168.30.2 with monitor IP of 192.168.20.1
Site 2 Gateway for route to site 1 - 192.168.30.1 with monitor IP of 192.168.10.1

Site 1 static routes 192.68.20 Net via Site 1 Gateway
Site 2 static routes 192.68.10 Net via Site 2 Gateway

This configuration worked between sites in the previous setup -- I have changed to OPNSense in Site 1 and Site 2 is on the other/older firewall.

Gateway monitoring doesn't even work on OPNSense.
I can monitor and get a ping response from Site 2 gateway from OPNSense CLI but not the default gateway in Site 2

Obviously I'm missing something in routing, but I can't see it ...

Anyone got any hints?
