Mark,

After review the debug output. It seems there is a
problem
at the other end of the L2TP tunnel cause the time
out that
is why it was not able to establish a connection. I
am
sure if I am interpret it correctly and not quite
sure
what to do with it. Please advice.

Look for the ===> Missed 5 keepalives
