Ok, technically ipx is considered a routable protocol. However,
Internet routers are typically not configured to handle IPX/SPX and
hence it can't go anywhere.
Plus, you simply don't bind ipx to your external interface. In my
example, the inside clients would run tcpip for internet based traffic
and run all of the file sharing on ipx which is guaranteed not to mix
with the outgoing tcpip (barring a misconfiguration that is).
