Possible flaw in UPnP support

Hello,
I've been using using Spotify for quite a while now and I'm mostly happy about the service. I miss a few artists/albums, but I keep my hopes up that It will get better and better :)

I have however recently seen, what i believe to be an issue with the UPnP support.
It appears that the wrong IP address is being reported to my router, generating some weird behaiviour.

A piece of the router log when spotify is started:

[INFO] Wed Mar 04 01:07:00 2009 UPnP renew entry 255.255.255.255 <-> xxx.xxx.xxx.xxx:46874 <-> 127.0.0.1:46874 TCP timeout:-1 'Spotify'

as you can see, it's being mapped to 127.0.0.1 (localhost)

Compare this to when some other applications are started.

[INFO] Wed Mar 04 00:38:25 2009 UPnP added entry 255.255.255.255 <-> xxx.xxx.xxx.xxx:21469 <-> 192.168.0.101:21469 TCP timeout:-1 'uTorrent (TCP)'

[INFO] Tue Mar 03 23:54:09 2009 UPnP added entry 255.255.255.255 <-> xxx.xxx.xxx.xxx:55927 <-> 192.168.0.101:55927 TCP timeout:-1 'Skype TCP at 192.168.0.101:55927 (792)'

Notice that these actually get mapped to my computer, not to localhost.

I might be off with this, but currently it's the only connection i can find.

The problems i get is that when i play music while on a wireless connection my router seems to block my traffic, it does however work while on a regular wired connection.

The block really seems to be connected to playing music with spotify since it happens everytime i press play (while on a wireless connection).

At the same time i would also like to request the possibility to disable upnp and make ports configurable so i can set up my own port forwarding.

Other than this, thank you for a great service :)

Regards,
Tommy
