use Squid : it is a high-performance proxy caching server.

OR
You can do this with IPTABLES rules too if u like to learn new things:

You need to have "rOOt access.

1) edit the file:
/etc/sysctl.config
add a 1 to the ip_forward like so:

net/ipv4/ip_forward = 1

save and close file.

2) at the prompt type:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Then at the prompt again type:

/etc/init.d/iptables save
or
service iptables save

Restart the network services, like so:

/etc/init.d/network restart
or
service network restart

All this is done on the firewall machine.

The eth0 is the network interface pointing to the Internet not your local network

This will let all pc on the local net to get online and the main pc will masquerade the internal IP address to look like the request is comming from the firewall pc.

Hope this helps.
