ahh i really dont know how you must make the links of IP host if you play a server with IP. someone who see that post maybe help us? :/
no you need just to keep it open nothing else. no need to change it place anywhere.
look as you told me you play a server with IP and you dont have any idea how to make the right IP for both Walker + server. soo i think when you run your walker its not cracked. i mean when you in and you want be sure if its really work it should show msg at walker that it works.
at Official server it works 100% because no need to change IP i have tryed it and Interlude Server with patch and it worked there too very well. now i am looking that problem with IPs :/
