I know of two that run on those systems.  The first is commertial
called TIA.  The second is freeware called SLuRP (or is that SLiRP).
They both are fairly good, with a slight nod going toward SLiRP for
being true BSD 4.4 Lite-2 kernel TCP/IP in userland.  Both also offer
NAT support because you had to do that in the SLIP/PPP emulation game
because some protocols (ftp, talk, irc, etc) are not firewall
friendly.
