Routing between two NATted subnets

ussmueller

Hello everyone,

I have a problem with my pfSense box. My pfsense-router has one WAN interface and two local, NATted interfaces. The local interfaces shall route between two different private subnets (192.168.1.0/24 and 192.168.2.0/24). My PC is in the 192.168.2.0 subnet. I cannot access the 192.168.1.0 subnet unless I explicitly set a route to the 192.168.1.0 subnet with the pfsense box as gateway. Why do I need to set the additional route although the default gateway is the same? Can I add an additional rule to prevent this? NAT is bound to the WAN interface and should not interfere with the routing.

Regards
Thomas

If you configured your firewallrules correctly this should work. (It works right now here where i am).
Could you post screenshots of your firewallrules?

Dear GruensFroeschli,

thank you for your support. I have attached the 1:1 NAT rules, the firewall rules for both the 192.168.1.0/24 subnet and the 192.168.2.0/24 subnet, the outbound NAT configuration, and the virtual IP settings. Furthermore I have not set any static routes. Maybe you have an idea what could cause this problem.

Thank you
Thomas

I resolved the problem. It was a wrong static route on my desktop PC.
