      Hi,

      Is it possible to get IP traffic through from the ‘server’ to an IP device without default gw on another VLAN ?

      See attached system sketch.

      I can ping the IP device from pfSense, Diagnostic | Ping

          @rmathisen yes, you would need to do a source nat, ie outbound nat on your vlan 20 interface.. So that when 10.10.10.10 is talking to it 10.10.20.70 thinks its 10.10.10.253 talking to it.

          If you would want 10.10.20.70 to start a conversation with 10.10.10.10 you would need to do a normal port forward on the .253 interface in vlan 20 to send it to 10.10.10.10. And 20.70 would have to send its traffic to the .253 address of pfsense.

          This is common work around for devices that either don't have a default gateway, or point to a different gateway than pfsense.

          that has been gone over multiple times, here is old thread same thing - nvr without a gateway, or different one than pfsense
