Hello all,

I am currently in the testing phase for ISA server 2004, and have run into abit of a problem. I would greatly appreciate some help as to where i'm going wrong.

My setup is 2 Nic cards, one internal on the 172.16.0.0 network and the other interface on the public network. There is no DMZ.
Web browsing external websites work fine, but the issue is internal resources.

I get the following error :
Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL). (12202) when accessing internal systems using their IP address, it works fine when using hostname though.

In the Directly access these servers or domains section,
I have tried adding hostname and or IP address of each server but i'm still getting the same error. If i disable web proxy and use the firewall it work no problem.

Any ideas?

Thanks
