      Greetings all,

      I have installed pfSense Beta 2.0 (built on Thu Oct 14 01:16:12 EDT 2010 ) and need a quick pointer.  I have two LAN segments behind my pfSense box (one WAN NIC and one LAN NIC), and I need pfSense to route both LAN IPs (172.16.150.0/24 and 172.16.201.0/24).  I looked thru the documentation and ran a number of searches but no exact hits.  I think this can be done using an alias on the LAN interface but I have not stumbled upon the right configuration.

      Can someone please point me in the right direction?

      Thanks,

      -Ron

            If you want access through WAN on both subnets, you will need to add another allow rule on LAN for the other subnet and I think you need to manually add another outbound NAT rule for the other subnet (change to manual outbound NAT).

              @Efonne:

              Exactly!  It took a few minutes to get it working but it works great now.  Just for future reference (so I can remember), to add a secondary/additional IP for the LAN segment:

              • Click Firewall–>VIPS and create a new IP Alias for the gateway IP Address (ie: 172.16.155.1/24)

              • Click Firewall-->Rules-->LAN and add the new subnet (Proto: *; Source 172.16.155.0/24;  Port *; Destination *; Gateway *)

              • Click Firewall-->NAT-->Outbound NAT and enable Manual Outbound NAT.  Click Save/Apply.  Then, add a new NAT rule using Interface: WAN;  Source 172.16.155.0/24; Source Port *; Destination *; NAT Address *; NAT Port *; Static Port: NO

              Thanks to everyone for helping get this working!

              -Ron
