      Maybe DNS is misconfigured. If I remember correctly you need to have static routes to make sure that requests to your ISPs DNS server goes out correctly - policy based routing does NOT work for requests from the firewall itself.

        That is correct.

          Quickguide:
          At system>general, use one DNS from WAN, one from WAN2. Then add a static route at system>static routes to <dns of="" wan2="">/32 to your wan2 interface with gateway <wan2 gateway="">. That should fix it.</wan2></dns>

              the gateway of WAN2. You can see it at status>interfaces.

                Thanks, I got it working now.

                I dont have 3 WANS at the moment, but would it be possible to do policy based with 3 WANS using pfsense.  I ask because in system->general, there is only spots for two dns servers.

                thanks,
                Zack

                  In general yes. Unless the 2 lines with the dns server fail simultaneously you would be ok. I think you can add a 3rd, 4th, … DNS through hidden config.xml settings too (download your config.xml and duplicate a dns setting and add another dns server there).

                    Hi
                    i ve the same problem than described above .
                    :P

                    I ve made a load balencer pool based on 2 wan (static IP )
                    Load balencer work very well , (i ve putted rules in wan and wan2 for emule , then high id )

                    I m using opendns (that give me 2 dns adress , opendns work very well , better than mines isp ones  ::) )
                    then i ve filled first DNS field in :

                    System > general >  two dns server's field  and unchecked the "Allow DNS server list to be overridden by DHCP/PPP on WAN
                    "

                    and not in the dns forwarder , …..

                    Then , when 1 wan is unplunged , the total group is down ?!  ???

                    an idea ?

                      Gulgux,

                      What do you mean by " the total group is down" ? Do you mean that you cannot browse or that the link is down (and you cannot ping the gateway of the second link that is up?

                      If you cannot  browse then may be it is due to DNS server not being accessible. You need to make a static route so that the second DNS server is connected to via the second Link.

                        exactly , can't have a dns resolve in fact .
                        the second member in the group seem to be still working (emule traffic is okay )

                        then , yes,  dns problem …
                        i will try to put a static route , then i must put a static route on wan2 ?

                        regards

                          system>static routes:
                          add a route like "Interface OPT-WAN, subnet <dns-server at="" opt-wan="">/32, gateway <opt-wan-gateway>Then male sure you use this DNS at system>general as one of your dns servers (one from WAN and one from OPT-WAN).</opt-wan-gateway></dns-server>
