Hello i am Grim Reaper and I am going to show you how to get your game online if you have no router(just connected to the modem…)
First open up your control panel and look for something similar to this:
Then open it, and goto Exceptions tab and click on the Add Program button, and choose your server
NOTE:This will allow your server to go pass your firewall and connect to the internet.
When done adding your exception for your server, click on the Add Port button and type in your port.
It should look like this:
Port: 4001 or something
IP: 192.168.X(your ip…)
Then select TCP.
and do it again but this time select UDP
NOTE:When having both exceptions, it will allow other players who use wifi to connect.
And play and enjoy!
