Hi Jay:
I was looking around my "database" of messages in the ISA Server List,
working around the issue of configuring multiple subnets in the external
interface of an ISA Server 2000; so that I can route all traffic to one
network destination by one ISP and all the other traffic to the other ISP.
So I found this answer of you. But I have a doubt about this answer.
You said: " Add a route on your ISA server for only the 222.222.222.0
network."
I need to know: Where to add this route? Windows 2000 routing table?
Thanks in advance
Lic. Alexey Fernandez Suarez.

They're wrong. It's actually pretty easy to do.
If I understand you correctly, all traffic should go through one ISP, except
that traffic destined for x.y.z.0 network. This might be useful if you
wanted to dedicate an entire ISP bandwidth to a private remote office vpn
for example.
Join both ISP networks and your external nic into a switch.
Add a second IP address to your external nic.
Leave the default gateway on the primary IP.
Add a route on your ISA server for only the 222.222.222.0 network.
We've had this configuration with a failover script for 2 years. Actually
with 5 remote offices vpn'd to external firewalls.
