How do I open all the ports for ALL of the ips on my dedicated server. I opened all the ports for the main ip that I RDP (Terminal Connection) into, but I can't seem to open the ports for the other ips that I got from my dedicated server provider.

Do you know how I can open the ports for the other three ips I have?

P.S. The ips are all on the same machine
