Proxy on Ubuntu

[niharuce]

Presently I am using windows Vista with CCProxy for internet connection sharing on my network on which 5 clients are working.
I am planning for migrating to Ubuntu. Is there any way I can use to be the internet server in my network(with restricted access facility)?

I could not understand you properly. I assume you are asking for gateway and restriction facilities. For that forget Ubuntu and use the ready made packages available like Pfsense, smoothwall, ipcop or else if you wanna filter out only some IPs then you can use some shell scripting.
