Odd Multi-Wan problem

  • Let me start by explaining my setup:


    2 WAN Connections

    DSL 1 static IP
    T1 3 static IPs

    2 Servers with 1:1 NAT connections to 2 of the T1 IPs.

    Everything works great as long as the T1 is the WAN interface but I would like to switch the DSL to the WAN so I can do PPPoE and squid over the DSL for local web traffic. When I make the switch, some traffic can no longer access the servers behind the firewall. Is there something else I need to do that I am overlooking when I am using 1:1 on the OPT1 interface.  All of the access rules/Virtual IPs/1:1 Nat options seem to be correct since most clients don't have any problems.  I have tried everything I can think of and this is kind of a last resort.



  • what IPs have problems accessing your sites?  Do they end in .224-239?

  • The two that I just tested that didn't work end with .232 and .234. Are you saying this could be a mask related issue?

  • Excellent.  Thank you very much for the reply. I'll give it a shot tomorrow. I didn't think it was anything I was doing wrong.
