udm-utilities 
A collection of things to enhance the capabilities of your Unifi Dream Machine or Dream Machine Pro.
Contributing
Pull Requests welcome! If you use this functionality to do new cool stuff to your UDM/P please send a PR and share it with the community!
Custom Kernel
If you want to do a custom kernel with wireguard support, multicast, multipath routing that is now a possiblity. Please see the repo and please use at your own risk. This a much larger change than anything in this repo.
Custom Podman Builds for UDMP-SE
https://github.com/boostchicken/udm-utilities/actions
Extract the zip to the root of your device! Look at the assets on the Podman workflow.
General Tools
on-boot-script
Do this first. Enables init.d style scripts to run on every boot of your UDM. Includes examples to run wpa-supplicant/eap-proxy and/or ntop-ng on startup. Follow this readme.
It enables complete customization of your UDM/P and fills the gap that config.gateway.json left behind.
podman-update
Updates Podman, conmon, and runc to a recent version. This allows docker-compose usage as well.
container-common
Apply this after on-boot-script. Updates container defaults to maintain stable disk usage footprint of custom containers. Prevents logs filling up UDM storage full.
python
If you need python3 on your UDM, generally not recommended, can always use it in unifi-os container.
UDMP Persistence SSH Keys Script
https://github.com/fire1ce/UDMP-Persistence-SSH-Keys
Script to presist ssh keys after reboot
VPN Servers / Clients
wireguard-go
Run a Wireguard client/server on your UDM/P. Utilizes wireguard-go, not linux kernel modules. The performance will take a hit due to that.
WireGuard kernel module for UDM/P
https://github.com/tusc/wireguard-kmod
Uses a prebuilt linux kernel module, without the need to move to a custom kernel.
OpenConnect VPN
https://github.com/shuguet/openconnect-udm
OpenConnect VPN Client for the UniFi Dream Machine Pro (Unofficial).
split-vpn
https://github.com/peacey/split-vpn
A split tunnel VPN script for the UDM with policy based routing. This helper script can be used on your UDM to route select VLANs, clients, or even domains through a VPN connection. It supports OpenVPN, WireGuard, and OpenConnect (Cisco AnyConnect) clients running directly on your UDM, and external VPN clients running on other servers on your network.
DNS Providers
Install a DNS server that functions as a network-wide ad and tracker blocker, and which can also securely proxy encrypted DNS requests to an upstream DNS provider. Begin by following the instructions to setup on-boot-script and dns-common. Then, follow the guides below to setup either Pi-Hole, NextDNS, or AdGuard Home.
dns-common
Base configuration for DNS server containers, both IPv4 and IPv6. Utilizes MacVLAN CNI plugins to completely isolate the network stack.
run-pihole 
PiHole w/ DoH Image
Run Pi-hole on your UDM with podman. Also contains custom image for Pi-hole with cloudflared.
PiHole with DoTe 
Desigened by: https://github.com/chrisstaite/DoTe/
Alternative to mine which uses DoTe
AdguardHome
Run AdguardHome on your UDM with podman.
Cloudflare DDNS
Update your cloudflare domains from your UDM with podman.
Cool projects you can use with this
multicast-relay
https://hub.docker.com/r/scyto/multicast-relay
This is a docker container that implements https://github.com/alsmith/multicast-relay to provide mDNS and SSDP on a unifi dream machine. It will likely work on any multi homed host.
ntopng
https://github.com/tusc/ntopng-udm
Much better network stats for your UDM/P! Install this docker container and create an on_boot script to make sure it's always running.
LetsEncrypt SSL Certs
https://github.com/kchristensen/udm-le
Provision and renew LetsEncrypt SSL certs from your UDM/P.
https://github.com/alxwolf/ubios-cert
Similar to udm-le, adding different providers for SSL/TLS certificates (LE, ZeroSSL, BuyPass) and DNS API (all-inkl.com) currently not supported by [LEGO]https://go-acme.github.io/lego/dns/.
Unifi API Browser
https://hub.docker.com/r/scyto/unifibrowser
This is a docker container that implements https://github.com/Art-of-WiFi/UniFi-API-browser to provide a graphical tool to inspect the data structures available via the unifi API. Great if you are using the REST API for your own purposes and want to explore. Works with multiple controller versions.
Unifi UDM-Pro auto fan speed
https://github.com/renedis/ubnt-auto-fan-speed
A shell script with the goal to make the UDM-Pro silenced while still having good thermal values. It stops the build in service that monitors the thermal values, fan speed and connection of a HDD/SSD. After that it sets the thermal/fan chip (adt7475) to automatic mode. Once that is done it changes the thermal and fan values specified in the script.
Jumbo Frames
https://github.com/kalenarndt/udmp-jumbo-frames
Make your Jumbo frames work!
rclone
Run rclone container with Web GUI for offsite backups.

https://github.com/fire1ce/UDMP-Failover-Telegram-Notifications
Use telegram bot to be notified of a wan failover with local account
Unsupported / No longer maintained
