If I have AdGuard Home set up on my Flint2 - MT6000 do I need to change the DNS settings for each device (phone, desktop etc) to use AGH's DNS server address(es)? I assume no. I do not care really about setting them up as clients and logging and monitoring their traffic.
What about DoH settings in my browser? Is there any point in adding an ad blocking custom DNS server in Firefox?
Or since it is on my router already I assume that all devices on my network with use the AGH DNS and I assume that means the upstream DNS servers I set in AGH's DNS settings section, is that correct?
I also assume if I have a VPN or pseudo VPN's like iCloud Private Relay or Cloudflare's Warp or custom DNS profiles on any of my devices that will override AGH's DNS and those devices will use the DNS of the VPN's and/or the custom DNS I set per device, is that correct?
There are so many places to set DNS - router, browser, system settings - it gets confusing quick for me.
I am just trying to avoid my ISP's DNS, block ads and trackers network wide, have access to blocklists, and hide my traffic from my ISP.
There is no need to change DNS for each device/client.
Select the network card of device is DHCP, that the DNS address is supposed to be [router gateway IP], so the DNS request traffic of the device will go to the router ADG.
Please disable the browser DNS (including customized DoH, DoT, ordinary DNS, etc.). If enable, all DNS requests of the browser will go to the set DNS, not go to the router ADG.
If the client is using VPN client and it contains DNS services, all DNS requests of this client will go to the VPN, and will not go to the router ADG.
In order to avoid tracking, protect privacy, etc., you can enable VPN client and ADG on the router.
All LAN client network cards set to DHCP and disable the browser DoT/DoH, your traffic will be protected, DNS will not leak, since traffic go to the router's VPN and ADG.
On desktop at least I can set the IPv4 method to Automatic (DHCP) and the DNS to Automatic is that what you mean partially? On iOS I can just set IPv4 to Automatic and DNS to Automatic. No mention of DHCP in the wifi/network settings.
I just turned on AGH and added a few upstream DNS servers and some blocklists. And I assume - and want to confirm - that by doing that - using AGH - all devices connected to my MT6000 router and my Wifi network will use AGH and the DNS servers I put in the upstream servers section (unless I use a VPN or set DNS on the device). Is that correct?
Good to know that if I set up DNS in Firefox's DoH settings that it will override the AGH/router DNS.
Also good to know the same is true when using a VPN. There are settings/toggles in router UI page to override the VPN DNS and enforce the router DNS right?
I do not really want to - and can't currently - enable a VPN on the router. It would or could cause issues or headaches with some devices on my network and I currently only use free VPN's or pseudo VPN's like Warp and iCloud Private Relay. When and if I can afford a paid VPN I will re-consider maybe.
