Run PiHole on your UDM

Features

1. Run PiHole on your UDM with a completely isolated network stack. This will not port conflict or be influenced by any changes on by Ubiquiti
2. Persists through reboots.
3. PiHole persists through firmware updates. The on-boot script does not. If you update your FM setup on-boot again and everything should work.

Requirements

1. You have setup the on boot script described in this repo (https://github.com/boostchicken/udmpro-utilities/tree/master/on-boot-script)

Customization

• Feel free to change 20-dns.conflist to change the IP address of the container. Make sure to update all ip references and the iptables rules in on_boot.sh. The IP address can be anywhere from x.x.x.3 to x.x.x.254. .1 is reserved for the gateway and .2 is reserved for the macvlan bridge.
• If you don't want to use vlan5, just replace br5 with br(vlanid) in on_boot.sh and 20-dns.conflist, also update all the ips accordingly

Steps

1. On your controller, make a Corporate network with no DHCP server and give it a vlan. All examples assume vlan 5.
2. Install the CNI plugins with install-cni-plugins.sh
3. Copy udm-files/20-dns.conflist to /mnt/data/podman/cni (or a place of your choosing and update on_boot.sh symlink). This will create your podman macvlan network
4. Update your on_boot.sh to include the commands in udm-files/on_boot.sh. You can leave out the iptables rules if you don't want to DNAT all DNS calls to your PiHole
5. Execute on_boot.sh
6. Run the pihole docker container, be sure to make the directories for your persistent pihole configuration. They are mounted as volumes in the command below.

 podman run -d --network dns \
    --name pihole \
    -e TZ="America/Los Angeles" \
    -v "/mnt/data/etc-pihole/:/etc/pihole/" \
    -v "/mnt/data/pihole/etc-dnsmasq.d/:/etc/dnsmasq.d/" \
    --dns=127.0.0.1 --dns=1.1.1.1 \
    --hostname pi.hole \
    -e VIRTUAL_HOST="pi.hole" \
    -e PROXY_LOCATION="pi.hole" \
    -e ServerIP="10.0.5.3" \
    pihole/pihole:latest

6. Set pihole password

podman exec -it pihole pihole -a -p YOURNEWPASSHERE

6. Update your DNS Servers to 10.0.5.3 (or your custom ip) in all your DHCP configs.
7. Access the pihole like you would normally.
