So on my Motorola SBG6580 i cannot get it to port forward. I know how to port forward. i have experience doing it for multiple servers on a different router. But on this router i just cannot get it to port forward. i seached online and other people have this problem and they fixed it by leaving the external port as 0.0.0.0 and setting the start and end port as the same start and end point as the internal. the port i'm using 25565(yes minecraft). but that does not work. nothing i find online works for me and i refuse to go return the router. So can anyone help?
