Server blocking LAN responses over Wireguard VPN
I'm trying to setup Wireguard to use as a VPN on my server using this guide. I currently run Pihole on the same machine.
| LAN | 192.168.1.* |
| WG | 10.14.0.* |
| WG Server Addr | 10.14.0.1 |
| WG Client Addr | 10.14.0.10 |
The handshake succeeds, and I can even ping IP addresses. However, it doesn't receive DNS responses. I checked in Wireshark and see the following:
| WAN Client IP -> | Server IP | [Wireguard] |
| WG Client IP -> | Server IP | [DNS Request] |
| Server IP -> | Server IP | [DNS Request] |
| Server IP -> | Server IP | [DNS Response] |
| WG Server Addr -> | WG Client Addr | [DNS Response] |
| WG Client Addr -> | WG Server Addr | [ICMP Port unreachable] |
I'm admittedly pretty inexperienced when it comes to routing, but I've been at this for days with no success. Any help would be greatly appreciated.
Edit
I now realize that it would have been relevant to mention
