UniFi Home Network

In 2020 I decided to switch for the core network backbone of my home to switch to Unifi .

Hardware

• USG-3P
• US-16-150W
• 2x UAP-AC-Pro
• UAP-AC-LR

USG Dnsmasq (DHCP and DNS)

USG is actually running EdgeRouter OS. See Documentation for how to use cli commands together with the unifi controller.

mca-ctrl -t dump-cfg > config.gateway.json

Main reason for switching to configuration on file basis was that I wanted to use UGS as DHCP and DNS service provider for my network. Therefore I am using dnsmasq and UGS and configure hostnames and fixed IP addresses via config.gateway.json.

UniFi Network Application on K8s

At my homework a majority of services is runnning on microk8s . There for of course I wanted to have the UniFi Netwwork Application also hosted on K8s. I am utilizing a helm chart from the [kah][k8s@home] project.

A few remarks regarding learnings I made:

• For pairing of controller with the UniFi devices it is important that the ports of the network application are reachable from outside the cluster.
  • Using metallb as LoadBalancer: Reserving an IP range within the main subnet of my home network to avoid any more complex gateway based routing.
  • Seperating the TCP and UDP endpoints in two services
  • Make sure the two services are bound to the same loadbalancerIP (see doc )
• As metallb is already in place I decided to not use nginx-ingress (downside: the SSL certificate as created by UniFi network aplication is used).
