I will explain my configuration to you, I have two Lan networks each connected to a PFSense router (on the GNS3 software). I put all the IPs in /29 as in the attached drawing.

The goal is for PC1 to communicate with PC2.
I configured the two routers by adding the gateways and the routes.

my gateway goes from 192.168.1.0 to 192.168.2.0 and vice versa on the other router.

the route created in the lan (192.168.1.0) goes from the gateway 192.168.1.0 to the destination 192.168.2.0 (to reach the other pc) . Same for the reverse.

My routers have PFSense version 2.6.0.

I don't see why it's not working, could you please help me!
