TCP/UDP Open server

Hi,

I have a question for my KalOnline server. I would like to open my server for playing with few friends and I would like to know how can I open it? I need to open my port with 30001 for TCP and 50003 for UDP, then I need to adjust my inbound rules & outbound rules on my firewall? If somebody can help me with this, that would be appreciated.

Thank you very much for your help!
