wichid you just cant run the server if u don't have .net framework 3.5,and if you don't open the ports needed none can acces the server.Im useing ruter and the server works just fine if u are doing the server just for friends you can use hamachi its realy easy you just add the hamachi ip in the Realmd.conf and there wont be need to open ports i think.btw my server is connected to internet by wi-fi so that's not the problem.
