  I am with you.  Nothing here would seem to explain the 
  difference.  No '206' like in the other entry.


  Try accessing the image directly from both the LAN and WAN.
  Do not go through the scripts.  What do you see?

  View the page source for the page returned from accessing the site
  from the LAN and from the WAN.  What is different?

  What does mmenu1 do?  The parameters being passed in are different
  between what the log shows for LAN access and WAN access.  Whether
  this is significant depends upon what the parameters are for?
