There is a long list of options here:

http://en.wikipedia.org/wiki/List_of_router_or_firewall_distributions

My preferences are IPCop and Tomato Firmware, depending on the needed
complexity. IPCop will run on junk hardware and Tomato runs on several
home routers like the Linksys WRT54GL.

There are many IPCop add-ons, including DansGuardian, which is basically
a very effective porn filter. Like many/most on the list, both IPCop and
Tomato are configured via web interfaces.

Many people like SmoothWall or, for something more extensive, SME Server
or ClearOS (previously known as ClarkConnect). If you want a high
performance router, look at pfSense.
