AN EXPLANATION ABOUT OPEN AND CLOSED PORTS // 2008-03-04
If your Port 26900 is OPEN, you can LEAD a session and everyone will be able to connect to you.
If the Leader’s Port is OPEN and your Port is CLOSED and another musician wants to join, you may be blocking that third or fourth musician from joining the session.
BUT… even if Port 26900 is “Closed”, you can still connect to another musician over eJamming if your modem or router supports Network Address Translation (known as NAT). eJamming will attempt a NAT negotiation with the other musicians connecting to a session. If NAT negotiation succeeds, you will be able to join a session, or players will be able to join your session, even if you’ve failed the Port Test.
In case NAT negotiation fails to connect you to other musicians in a session, you can always manually forward port 26900 to your computer. We have worked with the website www.portforward.com to set up specific instructions to port forward port 26900 for eJamming on almost every model of router out there.
Once you’ve joined a session, it no longer matters if your port is open or closed to hear each other. The Port information only tells you if there will be problems connecting to a Session.
