Yes and i can log onto the server with my ipv4 as per the guides but then the guide has me log out and then log in with my ip addres which I give to the other people playing with me and that ip does not open the server currently. Last night the same address worked and had all 3 of us playing together on my server.
i figured it out. when my ipv4 address changed i needed to go into my router settings and adjust my port forwarding settings to the new ipv4. thank you all for the help. It's much appreciated.
