      hi,
      this is my first post here,
      please be patient.

      My setup is as folows:
      WAN x.x.x.190/27
      WAN2 x.x.16.177/16
      I configured my pfsense following this howto http://doc.pfsense.org/index.php/MultiWanVersion1.2,
      -added CARP VIPs on my first wan
      -created 1:1 NAT for my ips
      -created a rule on the LAN so all of my servers leaves on the correct gateway

      All works fine except that I can not connect to my services from any IP from the second WAN.
      I can se request reaching my servers with tcpdump and on the firewall log
      then enter the pfsense box (still tcpdump), but they does not leave the box. I can see all other packets leaving in the firewall logs but can not see those.

      Thanks for helping

        i solved my problem putting a router befor my wan2 nic.
        the problem seems policy based routing and the routing table

        even if i have a rule in my lan tab on the firewall,
        Proto  Source  Port  Destination  Port  Gateway
        *        Notranji  *      *              *    x.x.x.161      (Notranji is an alias for all my servers internal ips)

        all the traffic that should go to isp2 is not routed by this policy but according to the routing table,
        here is mine before putting the router inforont of WAN2 nic

        Internet:
        Destination        Gateway            Flags    Refs      Use  Netif Expire
        default                    x.x.x.161    UGS        0      165    vr0
        x.x/16                link#1            UC          0        0    rl0        <–here all my trafic is routed to the WAN2 gateway but according to my LAN rule it
        x.x.0.1        00:90:1a:a0:14:01  UHLW        1    1533    rl0    121                                        should go to WAN1 gateway
        localhost          localhost          UH          0        0    lo0

        x.x.x.165                      x.x.x.165    UH          0        0  carp3

        is there another way to solve this,
        coz I'm planing to have some more IPs from the other isp?
        thanks
