Ok, so, I’m ending up with an issue where I can ping Router A from a device on Router B, but I get Destination Port Unreachable if I try to ping a device on Router A. Likewise, I can ping Router B from a device on Router A, but I get Destination Port Unreachable if I try to ping a device on Router B.
I have the route added to Router A (192.168.1.0/24 via 192.168.0.2), I have masquerading turned off for wan on Router B.
