ISA requires two interfaces (external can be dial-up) if you expect ISA to:
1. handle protocols other than HTTP(S) and FTP (download).
2. act as a firewall
3. support Firewall Client or SecureNAT connections

Hi ...

Could you please clarify the following?

1) If the ISA server is not directly connected to the Internet i.e if it has
to go through another firewall (internet gateway which gives access only to
the ISA server's IP) and a router, and all other workstations are in the
same LAN Subnet, is it still mandatory that the ISA Server has to have two
NICs?
By the way, the ISA is serving only as a Caching proxy server.

Please suggest

Arun
