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.
