Straight into Pihole with Cloudflare upstream

This happened to my server last winter, got scanned and some random tried to join the server, luckily I had whitelist enabled.

Changed ports from default and haven’t had a problem since.

ddns also works and it’s free

If you can post your conf files for both pcs it would be a good start. (Censor your wan obv)

Did you use a third party service to set up WireGuard like pivpn or tailscale? Can you normally ssh between pc’s while local? Did you enable port forwarding for wireguard traffic on your router?
