24.1 Legacy Series / Slow DNS response times (Unbound DNS + Adguard Home) - how to fix?
« on: May 22, 2024, 08:29:10 pm »
I am experiencing issues with slow DNS response times (Unbound DNS + Adguard Home).
1. I have Adguard Home running in a container in Proxmox on its own VLAN xx.
2. In Adguard Home, I have defined Upstream DNS servers to 192.168.1.1:5353, and I have also defined Private reverse DNS servers to 192.168.1.1:5353.
3. In OPNsense, I have changed the Unbound DNS port to 5353.
4. In Services: Unbound DNS: DNS over TLS, I have defined: 1.1.1.1, 1.1.1.3, 149.112.112.112, and 9.9.9.9.
5. In System: Settings: General, I have set the DNS Server to the IP address of my AdGuard Home container.
6. Similarly, I have set the IP address of my AdGuard Home container under each interface in Services: ISC DHCPv4.
In Unbound statistics, I get:
Recursion time (average): 0.081140
In Adguard Home, I get an Average processing time of 82 ms.
Running OPNsense 24.1.7-amd64
AdGuard Home Version: v0.107.49
Do you have any suggestions on what I can do to reduce the response time?
