Not 7000? (for fileserver access)

It should be port 7002, but you said you already allowed that. Can you
'pts ex lschimmer' ? If you look at a wire dump of udp traffic, it
should be pretty easy to see what's not getting through. You should see
some packets being periodically sent, with nothing coming in the reverse
direction. And for the above example, I'd expect the client to be trying
to contact port 7002 on one of the dbservers.
