Connection to VPS only via VPN or SSH - eviltoast

Hey guys,

I finally come around and started the journey of self-hosting and decided to get a VPS. After securing it, by making login via public-key default, I installed CasaOS and instantly regretted it since it now can be reached freely from the internet. A while ago, I read that you can limit the incoming connection to only VPN and ssh. And configured a Wireguard-VPN on the server via pivpn. But the server can still be reached from the internet. So what do I have to do now? Is it even the right choice, or am I missing something? How do you guys secure your VPS?

    I agree. I have all my servers “in the open”, and only use VPN when I need to route my egress through a different geographical location. The reason I’m saying to use ListenAddress instead is because OP is already got the VPN setup, and seems like not going to change from it. No point introducing yet another piece of complexity such as firewall to the mix when their objective can be achieved with what they’re already using.
