This method should solve your issue:
$ gem install --http-proxy http://201.187.107.19:8080 rails
Note, the IP address and the port number refers to a proxy. You should search for a proxy list and use one of the proxies there.
This is sample site with proxies: http://www.cybersyndrome.net/pla5.html
Use gem install rails -v=2.3.11
or gem install rails --version=2.3.11
