Media Not Playing Over Internet

I've got another problem. Maybe bushman4 can help me again
I've setup subsonic, forwarded ports on my router, added exceptions to Windows Firewall, and it works great on my LAN. However, when I access subsonic over the internet, off my LAN, I have a problem.
Subsonic loads, all my media is indexed with cover art, everything looks great. But nothing will actually play. The flash player displays the length of the song, but won't actually start to play...
