3 networks routeing

  • Not sure if this is the right place to post this i am super new to pfsense.
    I have 3 networks  and  i would like to router traffic between all 3.
    I have 3 network cards and the network has another router for the internet 
    I would like all 3 to talk and get out to the net based  on the firewall in pfsens i am not sure if pfsense can even do this i have been trying for a few days and i cant even get 2 networks to talk this will need to have (no nat)

  • It should work out of the box as long as you assign pfSense an IP address on each subnet on the appropriate interface and create firewall rules to allow traffic from LAN to OPT1 & OPT2, OPT1 to LAN & OPT2 and OPT2 to LAN and OPT1.

    If you have a different default gateway for one subnet's clients, you need to push the routes to the other networks to them specifying pfSense as the gateway. The best way to do this is to use DHCP Option 121. You can also enable RIP on the clients and enable RIP broadcasting on pfSense. You can also just add static routes to the other router but this will make it asymmetric routing and choke the router with LAN traffic.
