(Keeping it in the list) That configuration works because of the setting you chose in the HTTP redirector. The disadvantage to that is that your client browser won't be able to authenticate because the HTTP redirector does not pass the authentication through to the web proxy service. If you want user authentication, you have to set the proxy information in the browser.

I read other your response to one of ISA Group that it is same to my trouble too. You explained 4 items, therfore I configure my ISA same to your commands but I have to setup my proxy in IE5 too, if I interested to active my Firewall. In previouse configure in Extention - Http Filter properties I selected first Item not 3th item "SecureNat Clients ..." (that you explain in item 3 in your mail) and my clients in LAN could access to Internet w/o any new configure of IE5 or Proxy on IE5. Now, please let me know that we are wrong in configuration or we need to more new setup of ISA Server for Access to Internet throgh IE5 Browser w/o putting any proxy setting. Best Regards Babak Dashti
