**The issue I am facing:**  
DNS service not running and FTL offline

**Details about my system:**  
Pi3B+ Raspbian Buster (10)

**What I have changed since installing Pi-hole:**  
I need to make network manager working for EAP wifi to be working properly.  
After installing network manager, the only way for it to work is to sudo apt purge dhcpcd5.  
I believe though that pi-hole can't work without it. Is there any other way?

Everything should work fine. You may break Raspbian by purging `dhcpcd` since that's how the entire OS is designed to handle networking, but all Pi-hole needs is a static IP address.

Hmm, I don't believe it is ok. If I try to repair my pihole, it reinstalls dhcpcd 😕 therefore it breaks the networkmanager again.

And then pihole still says DNS service not running and FTL offline

This should be fixed in Pi-hole @DanSchaper maybe you can recognize the user intentionally uninstalled dhcpcd ? Maybe add a setting to `setupVars.conf` (`DONT_INSTALL_DHCPCD`).

> [@Nickie\_emp](#):

These may be false positives. Try

```auto
sudo service pihole-FTL status

```

and

```auto
dig google.com @127.0.0.1

```

on your Pi-hole and see if especially the second command returns a valid response.

Oh cool, thank you for this!

So this changes :

to

And now I have to reinstall pihole? Or repair it?

Probably NM runs its own DNS forwarding service for caching.  
Which one ?

`sudo netstat -nltup | grep 'Proto\|:53 \|:67 \|:80 \|:547 \|:471[1-8] '`

Purge `dhcpcd5` again if want to have NM take over.  
But you have to configure a static IP through NM.

EDIT: and probably best to run `pihole -r` and select **reconfigure** when all finished/up/running.

Above is the one conflicting preventing `pihole-FTL` to bind to socket.  
Dont need the `dnsmasq` binary as `dnsmasq` is already embedded into Pi-hole's own binary `pihole-FTL`.  
You can purge `dnsmasq`.

It was already purged and NM has taken indeed over.  
And Under IPv4 Settings, under Address (optional) I have placed the Pi's IP/Subnet mask and the gateway of the router. 😉

Question: I want to bridge this from Wifi to ethernet. Wifi connects fine and I wanna bridge my lan and give the wifi's internet connected to lan to a router. The address stays the internal to the internal network. However the gateway, should now be the IP address of Pi?

I believe folks have gotten piVPN to work with Pi-hole.
