I have a dedicated server from 1and1 with remote access to desktop. one of the applications that I use requires to communicate to another computer on x.x.x.x:2222
whatever i do , I can't seem to be able to open port 2222. this port is required for online payments so I can't change the port as I connect to a supplier.
can someone kindly help me set this up ? I do not use any firewall (both software or hardware) apart from whatever comes with windows.
i really would appreciate a step by step help as i'm not that much expert on this.
many thanks in advance
