Conditional forwarding on UDM Base

Hi guys

im very new to NextDNS and so far it’s working really well, so much so that I’m moving over to it from Pihole.

my network has 4 Vlans

Vlan 1 - 10.0.0.1/24 - were UDM is located

Vlan 10 -10.10.0.1/24 - Home Network, pc’s, iPads etc

Vlan 20 - 10.20.0.1/24 - Guest Network

Vlan 30 - 10.30.0.1/24 - IOT Network

when I installed the NextDNS Client on my UDM, I Entered my Client ID and all devices on all Vlans are appearing in the logs correctly

but now the question.

how can I change the config on my UDM so that each vlan is assigned a different ClientID?

i have read the wiki document here https://github.com/nextdns/nextdns/wiki/Conditional-Configuration but I’m struggling with how I would set this up on the UDM, what commands to type into the UDM after login into it via SSH

i have created the additional networks in my NextDNS dashboard, which my 4 Vlans would use

any help would be gratefully received 

kind regards

Steve
