So im currently working on setting a simpel server up with a game server using port 30110 and 30120, but i clearly getting dossed like crazy, how is the best way to protect against this, like i have used the following tables.
Apache Full ALLOW Anywhere
3389/tcp DENY Anywhere
OpenSSH LIMIT Anywhere
30110 ALLOW Anywhere
30120 ALLOW Anywhere
4489/tcp LIMIT Anywhere
But for what i can understand here is that its open no matter what, not waiting for a service or anything... what is the best approach to open them so users can connect but no DDOS/brute attacks cant happen?
Im using Ubuntu 22.04
Thanks in advace!
