I use Freesco at home it's really very good.

The config is simple enough for anyone who knows enough about IP to be setting up a router anyway, no Linux knowledge is required (and indeed few Linux commands actually work)

It takes a while to boot from a floppy, and there doesn't seem to be any provision for backing the floppy up (except while the router is shut down), which is a pity (if you eject the disc, the router will start misbehaving in some respects as it needs to access this disc occasionally)

It has very low hardware requirements (8Mb 486), is pretty secure "out of the box" and works on most systems (Quite a few common ethernet cards are supported). A bit tricky to get right if you have non-plug and play ISA ethernet cards, but otherwise ok.


I run mine as a NAT router, DHCP server, DNS primary (for internal zone only!), and DNS cache. It also supports port forwarding but that's a bit ropey to set up.
