Internet access restrictions from the WiFi network

Print PDF

Because of a large number of indiscriminate bittorrent downloads of copyrighted material, and the subsequent legal notices that IITD received, all direct access to the internet from the WiFi network has been withdrawn with effect from August 8, 2014. Internet access from the WiFi network is now restricted to ports 21, 80, 443, 8080 and 8443 through the proxy servers. Please see the Network access and monitoring policy for details.

Proxy access through WiFI

Print PDF

From 1800 hrs on Feb 11, 2014 CSC is changing the proxy authentication mechanism for internet access when connected through the WiFi network.

When connected through the WiFi SSIDs IITD_WIFI{1,2,3} and EDUROAM, users will automatically be logged on to their respective proxy servers. Users will still be required to specify the correct proxy server in their system or web browser. The proxy server can be specified either as an automatic proxy configuration URL (such as or manual proxy configuration as proxy?? or IP-address-of-the-proxy-server:port (these parameters can be noted from the web-portal for proxy authentication). Users will be automatically logged out of the proxy server when they disconnect from WiFi.

IITD has become a part of Eduroam, a global Wifi roaming programme across academic campuses, through ERNET, India

Any faculty, staff or student of IITD visiting an academic instituion which is a member of the Eduroam programme anywhere in the world may have unlimited internet access by connecting their laptop or other mobile devices through the secure WiFi SSID called EDUROAM.  They will be authenticated by the WiFi authentication server at IITD.

In a reciprocal arrangement, any academic visitor to IITD from a partner academic institution will be able to connect to our campus-wide WiFi using the EDUROAM SSID and will have unrestricted internet access. They will be authenticated by their home institutions.

EDUROAM is available at several thousand locations in over 60 countries.

All members from IITD can connect to the EDUROAM SSID using the login uid@IITD.AC.IN and their IITD Kerberos password. They have to set their laptop/mobile to use IEEE 802.1x WPA2 Enterprise based encryption for authentication and use the EAP methods EAP-TTLS or EAP-PEAP with MsChapv2 as the inner-tunnel method. Please see IITD Campus Wifi for configuration details. The same settings will work from any EDUROAM enabled location in the world.

Mac, iPhone and iPad users can use the mobileconfig utility available at the CSC website to configure their devices for EDUROAM.

IITD users connected thrugh EDUROAM from within IITD will still have to use the IITD Proxy servers.
