Ok so let say you have 2 active servers running on the same computer, right? Now you change the two worlds to port 7171 and 7173. Now your loginport is 7171, so this means that players use your ip + port 7171, they get access to the two worlds in a login (like real tibia)right?, and after that you just select one charecter from any of the worlds and you are redirected to that world? No need to change the port to 7173 with an ipchanger?
Thanks in advance
