It could be better documented, it really means "don't do anything IPv6
related in NetworkManager, but don't prevent anything else either".  So
NM isn't touching IPv6, but the kernel also has IPv6 autoconfiguration
capability and that's what is likely running on the interface outside
of NetworkManager.

Once I changed it to "Automatic (VPN)" the "Routes ..." knob

Now you've allowed NM to handle the IPv6 configuration on the

Here the default is for "Use the connection only for resources for

applied. I did the same already for ipv4 to avoid that all traffic
through tun0.

Sounds right.

resources for this network" enabled my connection works as expected.

If something can be done about the misleading "Ignore", that would be
