Hi, I am consulting a company that wants to install an ISA Server on the LAN, but the addressing isn't on 192.168 or others private address. I'm tryin to install ISA as a web cache, b'se thre's also a Check Point Firewall/1 for security. Bypassin the FW question, I've tried to connect the internal network on the first LAN adapter, and the router on other side. Everything works fine, BUT ON INTERNET I LOOSE VERY WEB SITES AS THE SAME AS MY INTERNAL CLASS B NETWORK (192.160.0.0). I can't change the addressing, so I want to know how can I make this work. I think I've to reinstall ISA in Integrated Mode, and "joking" with LAT table, but I've tried and nothin' changed. I've readed around that it's possible Every help will be greatly appreciated Massimo Miccio
