I've tried this with IP spoof detection disabled but I still can't seem to get it to work.

The client has both a DSL connection with a /29 and a T-1 connection with a /29. They've had the DSL for quite some time and just got the T-1. They wish to continue hosting some services on the DSL's IP block yet change their default route for outbound packets to the T-1.

I've tried disabling the spoof detection and even disabling all of the ISA services to no avail. I simply can't get responses via the T-1 when I send traffic to the IP of the DSL interface. Perhaps the T-1 ISP is dropping the packets with their own spoofing rule, but I want to make sure that all of my ducks are in a row before assuming that. Your comments will be appreciated.

Hi Kevin,

out of the box, ISA server supports only one default gateway. Therefore only one external connection. However, check out some add-in products over at http://www.isaserver.org/software/ISA/High-Avail.-&-Load-Bal./

HTH,
Stefaan
