In Portainer I tried to setup MACVLAN with IPv4 and IPv6, so that Pi-Hole and Unbound can receive stable addresses and receive all IP traffic. However, when trying to create a network based on my configuration, I get the following error message.
invalid gateway address fd07:****:b70e/64 in Ipam configuration
The IPv6 ULA is exactly the one, I have assigned to the Fritzbox router. I have restarted the Synology and the router but the error message persists. Can you please help me to find the mistake? Many thanks in advance.
I agree. It is not a Pi-hole issue. I have posted this here as a section of Pi-hole users also use a Synology/Docker/Portainer/Macvlan setup and hoped to get some further instructions.
Thanks for pointing out that Docker only supports IPv4 out of the box. I assumed that Portainer would activate IPv6 during installation as it also provides the option to enter IPv6 network addresses but this is possibly not the case.
For now, I have reactivated an old RaspberryPi and it handles now all my IPv4 and IPv6 traffic. Thanks for your support, @Bucking_Horn !
