Do you use a separate Heimdall container for use with Tailscale IP
address?

Set up pi-hole as your dns server and

an-internal-dns-server
Also you can set up an exit node

I have an exit node setup, but I can't access the local IP address
when using exit node...

What exactly do I need to setup in tailscale for using pihole as dns
server?

Set it up also as a subnet router.
1. Enable IP forwarding
```
echo 'net.ipv4.ip_forward = 1' | sudo tee -a
/etc/sysctl.d/99-tailscale.conf
echo 'net.ipv6.conf.all.forwarding = 1' | sudo tee -a
/etc/sysctl.d/99-tailscale.conf
sudo sysctl -p /etc/sysctl.d/99-tailscale.conf
```
2. Advertise your subnet (in my case 192.168.0.0/24)
```
sudo tailscale up --advertise-routes=192.168.0.0/24
```
3. Enable subnet routes from the admin console

Uncheck "Override local DNS"
and set an IP for your pi-hole
https://login.tailscale.com/admin/dns

Ok, I'll give it a shot. Thanks

This not so much... any ideas?

Steps so far:

1. on Tailscale DNS page put Tailscale IP address as a global
nameserver and enabled "Override local DNS".
2. In the Pi-hole Admin page in Settings > DNS, selected permit all
origins.
