Docker Network and DNS-Rebind-Protection question


Recommended Posts

Posted (edited)

Hi, I just updated from 6.11.5 to 6.12.10 and because of the macvlan problems changed "Enable Bridging" to "No" and "Host access to custom networks" to "Enabled".

Most of my containers use bridge as network, DuckDNS uses host.

Since br0 is no longer available I use custom:bond0 for AdGuard and NPM, with each container getting it's own IP.

Is this a "correct" way of doing this or could this cause problems in the future?

When using br0 I couldn't access AdGuard when connected via VPN but now I can, why is that?

I just set up NPM with DuckDNS pointing to my local IP and I read online that the FritzBox should block that because of the DNS-Rebind-Protection unless an exception is specified.

In my case it works without. Does that mean DNS-Rebind-Protection doesn't work for some reason?

Thanks for your help :)

 

 

Edit: The DNS-Rebind-Protection can't work because I have set a custom DNS on my phone. When disabling it and using the router configured DNS it blocks it.
