I have installed UFW on Ubuntu 14.04. I used following commands to enable a port:
sudo ufw allow 9384/tcp
When I used the status command (sudo ufw status) it shows me that port is open for both IP4 and IP6.
To Action From -- ------ ---- 9384/tcp ALLOW Anywhere 9384/tcp (v6) ALLOW Anywhere (v6)
When I try to connect Shoutcast it keeps trying to connect to server on port 9384 and eventually disconnects itself. If I turn off the UFW then shoutcast works all fine (connects and streams).
netstat -alpn | grep :9384 tcp 0 0 0.0.0.0:9384 0.0.0.0:* LISTEN 18235/sc_serv
Is there anything specific I should be doing?
