Hello I have a LAN where users have configured their proxy settings to go through a proxy server (ISA 2000). This server is redirected/chained to another one (ISA 2004) but, of course, the request received by ISA 2004 are done from IP (ISA 2000) and username (ISA 2000). How can I change to redirect the requests form the users and see clients IP and usernames from original client at the ISA 2004? I need to know the usernames, I want to install a WebFiltering solution on the ISA 2004 and I need to know the IP and/or username from clients in order to be able to block as needed. Thanks in advance
