ssh delays 40 seconds

A little nudge is needed. All of a sudden, my attempts to ssh any of the 
other computers in my SOHO take 40 seconds before I am prompted for a 
password or pass-phrase. At that time I can log in and all is well. It 
is consistent in all directions.

I have made NO changes to ssh or any other config file. I don't believe 
it is dns because I can ping and connect quickly to inside and outside 
locations using x.x.x.x or www.blah.org from all computers.

I have attached the output of ssh -vvv with comments as to were the 
delay occurs. I need some help or direction as to what it all means.

I thank you

Robert

P.S I have also attached a network map.
