Re: Wireless Firewall Settings

Hi,

I'm afraid that's incorrect.

Messenger decides what port it's going to use, opens and forwards -that- port (actually
there's two of them), and then sends the request to the contact.

When the voice/video/file transfer/et al is over/cancelled, it removes the port entry.
