uhm once you have opened up a port like 7777 it dont matter what your ip is as tht port remains open

for example say your ip is this one day 987.43.434:7777
and 675.65.566:7777

aslong as you got 7777 in your server.cfg that will remain the port open and so anyone can connect to it even if your ip changes

hope that made sence if it did not I am sorry!
