How do I change my PiHole Ethernet Interface

How do I change my PiHole Ethernet Interface?

I just set up my first pihole system but accidentally clicked on the wlan0 interface during the automatic install. Is there any way I can change it to eth without re-installing?

Run pihole -r and select reconfigure. Then select the correct interface and IP.

I updated today and now I’m finding my PiHole is not serving DNS to anything on my LAN subnet, but does appear to work when I connect via PiVPN.

I believe this is because the update seems to have changed my PiHole Ethernet Interface from eth0 to tun0. How do I correct this?

In the admin console go to Settings > DNS. Select Listen on all interfaces and save at the bottom of the page.

To reiterate anyone that is hesitating running pihole -r (like I had to do this past weekend) it doesn't wipe the install, just allows you to make changes. I originally hesitated doing it because I thought I would have to start over fresh.

One-Step Automated Install - get started quickly and conveniently may install Pi-hole using the following command:

code :     curl -sSL https://install.pi-hole.net | bash

Or

Uninstall Pi-Hole :

code :     pihole uninstall
