Hi Paul.
One thing seems very weird from your ifconfig, and that may explain 
some of the problems:

 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
         tunnel inet 68.23.23.11 --> 64.86.88.11
         inet6 2001:5c0:8fff:fffe::d6 --> 2001:5c0:8fff:fffe::d6

The two tunnel endpoints above are the same. It's not that surprising 
to see a point to point connection fail if it points to itself.

According to the server, 2001:5c0:8fff:fffe::d7/128 should be the 
client endpoint and ::d6 the server. Was the template/linux.sh script 
modified recently? That may explain why the wrong endpoints are 
assigned.

Otherwise, the only other way to pinpoint the problem would be to 
manually run the TSP client in verbose mode (tspc -vvv) and send us the 
log.
