I have ISA 2000 running on windows 2003 server. 1) I've seen articles mostly deal with ISA servers with just two NICs. What happens if I add more than two NICs and attach public addresses and/or private addresses? Does ISA automatically assume it's in a trihomed DMZ setup? What I want to accompolish is add another NIC to my dual homed(?) ISA server, bind a private IP number and treat the traffic from this card as if it comes from untrusted network (not include the new IP in LAT). 2) Can I have more than one internal NIC? 3) What makes the ISA to think it's setup for trihomed DMZ?
