There is a firewall on both sides but I have had the client side
firewall off for the purpose of this test and the server side firewall
isn't blocking any outbound activity.

Possibly as best evidence (as mentioned in my original post and I feel
bad that in my last reply I didn't include my original post and all
replies), I have made one successful backup of this client using this
config but only when trying to backup less than the full partition.  In
the successful case, it was a 3G directory.  Yet every time I've tried
to back up the full partition (17G), I can't get past a successful
estimate even when increasing the etimeout from 900s to 2600s.  I would
conclude from the successful case that the firewall is not
interferring.

Thanks for suggesting the possibility.

Paul
