Iptables/netfilter is what you want : read
http://www.linuxguruz.com/iptables/howto/iptables-HOWTO.html
and of course
www.iptables.org

Here is an iptables file(attached) that can be used as a template to get started.

Change the IP addresses to fit your actual situation. Please don't use mine, they won't work for you.

This file uses NAT, Natural Address Translation to provide the services you want to deliver. It also opens up port 21 for ftp 23 for telnet(a no no), and 80 for web hosting.

All of the services you are talking about are provided by this machine to the network in my offices.

Just though I'd give you a leg up.

Hi,

if you want web proxy service you could use squid for example.

If you are not THAT familiar in using linux, you could install webmin which helps you through the configuration of several daemons and applications.
