Thank you again for Posting that information - My roommate and I just installed a new D-Link DGL-4500 Gaming router - works amazing; but we did run into the same streaming problem with my Sansa Connect.
I went into the “Special Applications” and added the MMS Rule and port information as described above - Works like a clock!
I have a screenshot if anyone needs it - I figured I could upload it here but I do not see how.
Anyway - Thanks again for the 3 days of Hel*P
