How can I keep my forwarded port secure? (kbin.earth)

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

Then using something like fail2ban to block bad acting connections is far more effective and you even get a security benefit out of it.

Also, when a few scripts try to connect via ssh DDOS your router then something is messed up. Either a shitty router from 20 years ago or you have a Bandwidth lower than 100kbps.

I have fail2ban running on the server itself, also it was a lot more than “a few scripts”
