I have installed ISA Server (integrated mode) and have disabled the firewall service since I only need the cache capabilities for websense. I have two network cards in and its sitting behind a firewall-1 firewall. (The NIC IP addresses are 192.168.04 and 172.16.4.2) I have both network addresses in my LAT. When I tried taking one off, I lost my connection to the server entirely. The main problem is, from clients on the 172.16.4.0 network, I'm not able to ftp (isa as proxy)out. Can anyone help please !!!!!!!!!!!!!!!!!!!!!!!!!!!
