>>11103132>I open the ports required by the gameBy default, most of your ports are "closed". Ports can be "opened" by your router for certain tasks. A closed port cannot receive or send certain information. This is for the sake of security. An open port can send this information, and having a few opened ports is essential for hosting a server.
>I hope you can port forwardPort forwarding starts with logging into your router. For example, you may type 192.167.0.1 (this number depends on your router, ex. dell or rogers) into your URL bar and hit enter. This would take you to your router's login page. You must find your router's username and password. Generally it is the same for everyone and can be found by looking up "How to log into <BRAND> router". Once you're in, try to find the page related to port forwarding. When there, search up the ports needed by a specific game (in this case Terraria) and add them to the list of forwarded ports.
>I'm on linuxLinux servers are more stable than windows ones. I'm on Debian. Might be good in your case because you have shit hardware.
>Pinging my portIf a friend pings the port the game uses (can be done from a terminal in linux), they can see if it is open or closed. If it is closed, it will be impossible for anyone to connect.
>connecting to myself through my IPV4Go to this page:
https://www.whatismyip.com/https://www.whatismyip.com/Your IPV4 is there. It's what people will use to connect to you. It should look something like 88.251.88.199 or whatever. If you enter this yourself and cannot connect, it is certain that others will also be unable.
