I notice that my mac looks at the firewire bus and sees it as a
possible connection (fw0). Does anyone know of a firewire ethernet
connector that works? Can't find any...

thanks

They're not necessary. FireWire networking works over FireWire cables,
without adapters. It provides no real advantage over 1000BaseT (Gigabit)
Ethernet and causes some difficulties when using storage devices on the
same bus, so nobody uses it for networking.

You don't do ethernet via FireWire, at least not that I've seen. What
your machine is showing you is that you can do IP over FW and that's
accomplished with a normal FW cable.

FWIW, IPv4 over FireWire is described in RFC 2734:
