Looking for a good guide on getting this setup via docker and AD LDAP, any pointers?

Who's your DNS provider? I use cloudflare and powershell script and hits their API. Works well

Same but powershell. Works like a charm runs every 5 minutes

You can bound ufw rules to interfaces, so you can allow in only on the wg0 interface and not eth0 interface.

Glad it's working! I love wireguard!

Hmm do a traceroute and see where it's dying. Can you ping inside IP of the tunnel on the wireguard server? What about outside?

What did you deploy in docker, firezone or basic wireguard?

Does your phone say connected and you see both incoming and outgoing packets? Is there a firewall in place on the wireguard host (ufw maybe)?

If you have nmap available you can also check port status.

Good thing about wireguard is it's really simple. Google should get it done, if you get stuck send me a DM. I started with basic wireguard, I now run firezone in docker as I like the frontend.

I would go with wireguard VPN or something like cloudflare tunnels or tailscale. With wireguard you'll need to open up an external port and forward to your VPN host, but wireguard uses UDP so no one can probe it for responses. CF tunnels and tailscale you don't have to open up holes in your firewall which is nice.

You also have the option of using a proxy and opening up 443 publicly on your firewall, but unless you know what you're doing I'd leave that closed until you learn more.

Yes

I would get a domain name and use ddns to update your rotating IP. Then I would setup wireguard VPN in split tunnel and have your parents network tunnel back to your piholes for dns resolution.

I use cloudflare API for ddns updates but there are plenty of choices for that. If you're using cloudflare for DNS just keep in mind you can't proxy the DNS entry for the ip for your VPN host as CF only forwards traffic over certain ports and they are not configurable (on free plan anyway not sure about paid).

Don't get rid of it, install Kodi and/or Plex on it

+1 for dst nat on googles dns servers back to my piholes
