Hello Bill!!!!

I don't know if this is possible for you but heres my setup!
One ISA server which is connected to a ISP. this is our default route to the
internet. If the first server fails, we have another ISA server which has a
connection to a different ISP, to take over. The second have stong policy
and is just allowing webacces to go thru. It has worked well for us and the
redundancy is OK. I set this up in the client configuration.
I don't know if this was what you were looking for exactly. Just a thought
on how you could solve the problem if the first one goes down!
