Proxy Server CCProxy lets all computers on the LAN access Internet through one single Internet connection. Just need to install Proxy Server CCProxy on the server which can access Internet directly and the other PC clients can connect to the Internet through the proxy software. It will provide you a cost-effective Internet connection sharing solution without losing ease of use and peace of mind.
Hope your problem will be solved, let me know if I was of any help or not.
