      @hoba:

      In your special case you can remove the static routes for the dns servers as they are directly in the subnet of your WAN interfaces. Does it work then?

      I will attempt to try this later on tonight.
      Thanks hoba

        hey everyone
        I have got my network setup as i described earlier, except i have use ISP dns servers, not my linksys routers,  and all is working properly on the LAN, however, if i try to loadbalnce on an OPT interface, I lose DNS resolution.  DNS forwarder is turned on.
        My static routes are fine, traceroute shows proper gateway, netstat -rn shows both dns servers properly.  and like i said everything works on the LAN interface but not the OPT.  Any ideas on that one?

          What version? This sounds a lot like a multi-WAN NAT bug that was fixed in 1.2, if you're not running 1.2b1 you should.

                  Must be a configuration issue. It's working fine here and for a lot of other people. Try to rebuild from scratch following closely the documentation.

                    OK I have rebuilt from scratch now like 10 times following the guide to the word, and still having the same issue.  DNS resolution does not work on the OPT interfaces with the DNS forwarder turned on when the gateway is set to the load balancer.  If i set the gateway to the default then DNS works fine.  On the LAN interface DNS works fine with the load balancer.. I don't know what to do.  Its driving me crazy.

                    I am at a total loss for what to do.  It seems like this should be working. I have even gone to the lengths of replacing all hardware, except for my 4 port NIC.  That NIC has the LAN and 3 OPT interfaces

                      Eric, post your configs. Preferably screen shots of your loadbalancer and lan rules. Your network diagram with ip addresses would also be useful in case of misunderstanding.

                        anything else? i'll be happy to post, i would really like this to work properly.

                        Thanks guys
