Sounds like a reverse DNS problem to me.  I've seen similar long
delays in getting a connection going.  Once logged in then everything
seems fine.  In each case, I've traced the problem down to the server
not being able to reverse resolve the client's hostname.  The delay
I've seen is the amount of time it takes for the DNS lookup to timeout
so that the connection can proceed.

Regards,

Tony.
