Hi all, I am behind CGNAT, but my ISP router is allocating real IPv6 addresses to my devices that can be exposed. I have a Proxmox and I have installed Wireguard on an LXC container and configured it to listen to the IPv6 address.

I was wondering if I need to do something else to protect my Wireguard installation? I have exposed only the default UDP port to the outside and port scanners are not working on UDP ports as far as I know. Shall I do something else to protect my installation or the attack vector is already minimal and doesn't require further hardening? What's your opinion?

I did basically the same a few months ago, works really well in combination with DDNS.

Just make sure to keep WireGuard up to date from time to time to get rid of any potential vulnerabilities :)
