10.  How to use Direct Internet Access (No Proxy) ?

 

      Please see http://www.iitk.ac.in/cc/direct.htm for details on how to set and use Direct Internet Access (No Proxy).

 

      For direct internet connection through ironport machines please see http://www.iitk.ac.in/cc/ironport_noproxy.htm for details.

  

      For direct internet access from the residential areas please consult the link: http://www.iitk.ac.in/cc/res_no_proxy.htm 

 

 

11.  I am not getting authentication page while using Direct Internet Access (No Proxy) ?

 

      This may happen because of following two reasons:

      1. The Fortigate Firewall for Direct Internet Access allows only 5 simultaneous authentication requests. In case it receives more than 5 requests, it

          treats the client machine as infected and blocks the authentication for 3 minutes. This process may repeat and you may never get authentication.

          To avoid this situation, clean your machine from all virus and worms (infections try to access the Internet in the background and generate authenti-

          cation requests), remove all the Internet applications from Startup menu and do not start multiple Internet applications simultaneously.

     2.  172.31.1.130 is not set as the Primary DNS.
