How To Make A Server Public

Hi i have been trying to make a server for private gmod/ Garry’s Mod to record gameplay and i have got to the point where i have the server but it will not let my friends join. I believe i did the port forwarding correctly but for some reason the server only lets me join. Can anyone help me?

Try restarting your router after you have opened your ports. Also, ensure that your software firewall is not blocking the server/your game.
