Yes. Except for a couple of standard ports that are likely already open, you need to open some more ports. Here is the list:
|TCP (HTTP)||80||Ok, you wouldn't be reading this if you hadn't this port open...|
|TCP (FTP)||21||Used from the software to download and upload tracks (while in a session)|
|TCP (HTTP)||5000||Used for exchanging setup messages between users in order to establish a connection. Will be dropped soon, but currently still used.|
|UDP and TCP||19302||Used for establishing a connection between users (for all the geeks out there, this is used for STUN)|
|UDP and TCP||3478||Used for establishing a connection between users (TURN)|
|UDP||50000 - 65535||
Very important: used for the actual audio connection between users. The range is very wide, but you can try to restrict it to 50000 - 55000.
We are currently working on reducing to a minimum the number of required ports, so please come back to this page: we will update it often!
