ISA Server 2006 Web proxy issue

Avatar of Mc2102

Microsoft Forefront ISA Server
10 Comments1 Solution1595 ViewsLast Modified:
Hello,

I have the following setup

Workstation <----> ISA Server <----> VPN tunnel <-----> Sonicwall <------> Webserver

From the 'Workstation' I am trying to open a webpage which is running on the 'Webserver' vi HTTP and the page does not open. I can ping and telnet to port 80 on the workstation to the webserver. If I am in the same LAN as the webserver  I can open the page without a problem from any machine but as soon the traffic flows through the ISA server I see an error page saying that Web proxy was not able to reach the host which is of course nonsens because there is other traffic flowing through the tunnel as well. I do not want the ISAServer to do any chaching or anything - I want the ISA server to direclty forward the traffic to the webserver and that is it.

Can someone please help and let me know what I need to change on the ISA server to get that to work?

Thank you
