Hi,
I have am not particularly technical (to say the least), so please bear with me.
I set up adguard home on Home assistant, since my firewall (firewalla gold), which does a pretty good Job in filtering ads, does not perform those on queries resolving through 3rd party VPN client, which I need for my google and alexa home, and especially my streaming services.
I have had a this unused subscription with SmartDNS proxy, which allows me to bypass georestrictions without using VPN, so I decided to set up a subnet for those, with adguard home doing the filtering, and smart DNS proxy being the upstream DNS.
I am using http with port 80 to access home assistant (I know it’s not the greatest, but it’s from inside the home and easier to access. and manage. I also tried adding another fallback upstream DNS server (1.1.1.1) to make it work, yet it doesn’t.
After configuring adguard, it gave me 3 IP addresses it would listen on after initially only giving out (as shown in the manual part of the ui only 127.0.0.1, but when setting that one as relevant subnet(router) DNS, nothing was going through. I am not sure what I did, but then several more showded up including 192.168.1.12 (the IP of home assistant server), but also 172.30.32.1 and ::1 (have no idea what that means). I have enabled firewall rules between the subnets, and specifically to 192.168.12 and since I’ve noticed I need to allow external 53 port, also 192.168.1.12:53.
At this point, queries started coming in, but nothing that I actually typed on the browser as url (just some system processes of smart home devices “talking to each other”. One strange thing I noticed, that there were many blocks that should not be there, for example, homebridge being blocked from lg tv based on filter, yet both are in my home and my goal is to block external (lg in this case) certain traffic and not from one local device to another.
I tried to tinker with the DNS settings, to add all the features for local clients, even allow clients in a list (just to try out if it helps I realize that would only limit the number of clients with access but just temporarily, I tried to change home assistant DNS from 192.168.1.1 to 192.168.1.12 and back, of course create a static IP for home assistant on lan (on HAAS side it is already static on the router) but nothing seem to change. on the subnet using adguard as its DNS server, I can not resolve any domains, they don’t appear on the network flows of my router/firewall (which is being bypassed compltetly for DNS)nor on the query log of home assistant. I can only surf on segments that aren’t using AdGuard Home DNS.
I am attaching soeme screen shots from the UI of adguard, logs, network settings home assistant and whatever I could think could be relevant and hope you can help me come up with a solution.
Would very much appreciate any help, and please try to use the “adguard home for dummies” version of your answers, since I admit to being such
