I just setup a minecraft server on an old laptop, but to make it acessible i needed to open up a port. Currently, these are the ufw rules i have. when my friends want to connect, i will have them find their public ip and ill whilelist only them. is this secure enough? thanks
`Status: active
To Action From
22/tcp ALLOW Anywhere Anywhere ALLOW my.pcs.local.ip`
also, minecraft is installed under a separate user, without root privlege
no. The default port is fine. Changing the default port does nothing for security. It only stops some basic crawler, when you are scared by crawler, then you should not host anything on the internet.
The volume on 22 will be a lot higher than a non default port. With 22 open my router was basically getting DDOS’d at times
