I was using NextDNS when I decided to get an UniFi Dream Machine (UDM) and switch to the built-in content filtering. However, I wasn’t particularly impressed with its beta feature and after using it for a few months I decided to turn back to NextDNS.
Essentially, I had SSH already enabled on the UDM so I’ve installed NextDNS with:
sh -c 'sh -c "$(curl -sL https://nextdns.io/install)"'
An error is noticed as is unable to start the service the Ubuntu (Debian) way. Well, this is UniFi OS so it can be ignored.
The prompt is awaiting for a Configuration ID to be provided but we do that below with a separate command to cover multiple IDs, so I’ve just pressed CTRL+C.
I have then set a specific configuration to match my NextDNS Configuration IDs with the different Networks on the UDM, and restarted the service:
nextdns config set -config e2h243 -config 192.168.100.0/24=sdgd12 -config 192.168.2.0/24=534567 -setup-router
This way I can view the Logs in the UI for the individual LAN devices. E.g.:
The service logs are also useful to monitor after the restart:
watch -d "nextdns log"
UniFi Dream Router update: On the UDR, in order to get to see the correct hostnames in NextDNS we also did:
nextdns config set -auto-activate -report-client-info
