Hi John,
I have one as incoming and the other as outgoing for right now. My
internal isa goes to a different outgoing ISA. I did this as I move to
new IP address. Would it be possible to have 2 nics for all machines in
the DMZ and have different gateways per nic?
Thank you,
Joseph

That will work except the servers in the DMZ need to have a gateway
configured. Unless you configure with 2 gateway IPs, they will only
communicate through 1 ISA.
