If the token ring side doesn't have a default gateway without going
through the bridge it will try to source route the packets which is
probably causing the problems you see. TR can support either 18 or
30 bytes for the source routing information, Linux only supports the
18 bytes at present. We do have a complete source routing update
waiting for the 2.4 kernel as soon as its released. If you want try
a copy now to see if it works head over to the web site and grab
a copy (www.linuxtr.net).

TR->Eth bridging is nasty at the best of times, its normally far
easy to actually route between the two rather than bridge. An old
pc sitting around doing nothing would be ideal for this.
