We've recently installed the above with two ADSL lines (seperate static IPs) on WAN 1 and 2. These have been set to Load Balance with autoweight. No load balance rules have been set but with both lines connected response times from the internet go through the floor (>3000ms for a Ping!).

As soon as we disconnect one line, things go back to normal response but of course we've now halved our potential throughput.

So it appears the two WAN ports are fighting over connections - any ideas how to stop this?

TIA.
