allow internet access to VLAN6 but block access to other local IPv6 networks?

[skywalker007]

I need a quick inspiration:
On IPv4, i can easily create a rule that allows internet access to a certain VLAN and excluding access to other local networks by inverting the destination.
With IPv6 (track interface), I don't have static networks. How would I craft a rule to achieve the same which would work with any IPv6 network assigned to the other interfaces?

thanks, Till

Ignore the question.
It works with a group of the default alias networks
