From my experience if forwarding the port 7777 does not work at all even if you did everything right try making a new port in range from 1000-5000. For example instead of making a server like this... 120.0.0.0:7777 use 120.0.0.0:1234 of course you would then have to forward the port 1234 but if the port 7777 does not work at all it is most likely something is blocking it...
