HI, You require only one NIC for ISA in cache Mode. The default Gateway for ur cache should be a Firewall or Router etc.Iam running cache server with one NIC.Its not recommended with two NIC for cache server(especially when placing at the edge of Network). According to ISA docs.

You need at least two NICs, or you may be bothering by the error log on W3SVC while the cache function may still works. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: g.vinay@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
