Proxy server

A proxy server is a computer that acts as a gateway between a local network and a larger-scale network such as the Internet. In our scenario we are using Squid, the open source proxy server to get all government websites and e-governance applications in your LB network

How to install proxy server

  1. The proxy server is recommended to install in the server where VPN/KSWAN is directly connected (See B in above diagram)
  2. Download the proxy server and extract the zip file. It is customised for installing in LSGI which has KSWAN/VPN network, it will work only on Win 2000 and above. The user required administrator privilege to install the proxy server.
  3. Run “Squid-win-setup.exe”. Click on ‘Install’ button then Apply. Then it will show the installation log in shell. DO NOT CLOSE the black window, wait a while to complete the installation. The black screen will disappear after completing the installation. The Squid proxy server will install under C:\squid.  Screenshot follows
