The best way to do this is with an external "link aggregator".
ISA doesn't support multiple external interfaces (the second will be seen as
"spoofed").
You can avoid the spoof alerts by following the instructions here:

But you'll want to disable that setting once you switch over.

Subject: [isalist] Multiple ISPs
http://www.ISAserver.org
We are in the process of changing T1 providers. We have not discontinued
service from the original provider yet. My hope was that we could have both up
while the DNS changes were propagating. The line from each provider comes into
a separate NIC on the ISA 2000 machine (running on Windows 2000). Each NIC is
set up with the appropriate IP addresses. However, people trying to reach our
websites from outside are sometimes able to get in and sometimes not. (It
seems to be a problem mostly for those who still see the old IP addresses.)
Is there something special I should do in the ISA settings to allow the use of
two ISPs? (I believe I have set up the correct web publishing rules. However,
I really don't know that much about networking, so things get a bit confusing.
I still don't see why access would be intermittent.)
Thanks.
