I don't think so, but I'll look into it in more detail.  I have a NAT 
router that (as I believe I have it configured) just blocks connections 
from "outside" to servers running on the LAN (except for specified LAN 
IP and port combinations).

I'll check on this.

Something I've just noticed is that the timeouts seemed to occur mainly 
in certain newsgroups.  I've manually deleted those 
from /var/spool/news/interesting.groups and performance seems to have 
improved.  When I think leafnode has caught up with the others I'll try 
putting them back into use, one at a time.

Thanks,
Adam
