Smoothwall is a fine Linux distribution that is perfectly suited for your
goal, that is, if you have an old machine laying around somewehere. It will
then act as a stand alone firewall between the RED zone (the internet) and
the GREEN zone (your then protected network).

In my setup, I wired the GREEN nic to a hub.

Given a third nic, you also have the option to implement a DMZ.

Apart from the DHCP server, the system also has an intrusion detection
system, a web proxy, a caching dns, port forwarding possibilities,

Best of all: it's freeware!
