Russell,

   I checked the IP address and used the current one each time.

   Thanks for the pointer to tcptraceroute.

   Could the problem be that I no longer use port 22 for ssh? Before I left I
tested the ssh connection using the high port number on the LAN and it
worked flawlessly in both directions.
