I have converted this to a discussion as this does not appear to be an issue with AdGuard Home. I setup a test environment with a fresh install of AdGuard Home within Docker, and enabled IPv6 for a default bridge network. Prior to completing this, I received the same error you did. After enabling IPv6, the issue disappeared. |

The Mikrotik router has no option to configure the Docker daemon or to set up the default IPv6 bridge network. The container interface was configured with an IPv6 gateway, but somehow it was not set as the default gateway inside the container.

I realized that the router's container interface was configured with an incorrect IPv6 address and netmask, Thank you for your attention. |

Prerequisites
I have checked the Wiki and Discussions and found no answer
I have searched other issues and found no duplicates
I want to report a bug and not ask a question or ask for help
I have set up AdGuard Home correctly and configured clients to use it. (Use the Discussions for help with installing and configuring clients.)
Platform (OS and CPU architecture)
Linux, ARM64
Installation
Docker
Setup
On a router, DHCP is handled by the router
AdGuard Home version
0.107.48
Action
Tested upstream servers and IPv6 was unreachable.
# ping 2800:3f0:4004:807::200e PING 2800:3f0:4004:807::200e (2800:3f0:4004:807::200e): 56 data bytes ping: sendto: Network unreachable
Expected result
Remote IPv6 addresses should be reachable.
Actual result
All remote IPv6 addresses are unreachable.
Additional information and/or screenshots
I've set up an ADH container on my Mikrotik router and it works fine for IPv4 addresses, but not for IPv6.
As a result, I can't reach any IPv6 upstream DNS servers.
The container has a valid IPv6 under the router.
I can ping LAN IPv6 addresses, but not remote ones.
Then I realized that the container does not have a default IPv6 gateway set up.
Only if I manually add the default route, it can reach IPv6 addresses.
However, if the router is rebooted or the container is reset, the default route is lost.
My assumption is that it should have set the default route dynamically.
Any idea why it is unable to add the IPv6 default route?
