I'm really new to this and I know it has something to do with vpns. I don't want to leave my computer on all the time because of the bills. Would love some help, thanks!
Buy a VDS from NFO and create your own gameservers, don't host it off your computer or expect to crash 24/7 and for your internet to go down since your ip is the host and anyone can see that.
If you created a server on your computer is not a problem the only problem that can i have his when you are your computer the server turns off I advise you to go to a special host gmod or I buy a machine dedicate
