Trying to use zerotier to connect to adguard instance remotely on android for DNS

Hello,

I’m currently running an instance of adguard as well as zerotier as dockers on unraid. Zerotier is running in “host” network mode and adguard is running as a “br0” network and has it’s own private local ip. I can use zerotier just fine to access my other dockers but not adguard because it has it’s own ip. I’m using a unifi dream machine as the router/firewall if that’s relevant.

How can I access adguard remotely using zerotier? Specifically I’d like to use the adguard instance over zerotier as my DNS server for my android phone so I can have adblocking no matter where I am. I think I might need to setup a static route but I can’t quite wrap my head around how it works or if I’m on the right track. Any help would be greatly appreciated. Thanks!
