i have the same Problem .
here is my setup :-
I have an ISA 2004 Server SP 2, ( but i do not know if its setup as a Proxy Server or as a firewall), and a Fortigate firewall.
the ISA Server Work as Secure NAT or NAT Client for the Fortigate.
the Fortigate - Internal IP Address is :- 192.168.1.100 / 24 .
The ISA Server Has 2 Nic as the Following :-
1- First Nic have this IP ( 172.16.1.3 / 16 , No GW ), and its Connected to OUR LAN.
2- Second NIC Have this IP ( 192.168.1.22 / 24 , GW 192.168.1.100 , DNS 18.104.22.168 ). this is ISP DNS.
3- All the Clients Gateway is 172.16.1.3
4- All the Clients are configured to work as Web Proxy client , and not Firewall Client . " by putting the ISA internal IP on Proxy server in the Web Browser " .
The ISA is ISA 2004 Std SP2.
My problem is that certain links on sites will not work and come up as page cannot be displayed. For example when logging into yahoo mail, I go and click the inbox and it times out. Several other sites including ebay do it as well. I believe it is a problem with "redirecting pages" and the ISA is screwing something up.
When bypassing the ISA server it works fine (while still going through the Fortigate ). So the problem lies with the ISA. Also this is a network issue and not individual machines, al machines are doing this. Any suggestions or comments? Anyone seeing this problem too?
ISA 2004 is one a WIndows 2003, SP1 machine.
