Using IPv6 Dynamic Prefix in Firewall Rules

[mloiterman]

I believe 2.5.2 has introduced a new feature that will allow one to use the currently assigned IPv6 Prefix in firewall rules. The idea being that the rule would automatically populate the new prefix if it changes.

This seems like a nice feature, but I can’t find any documentation on how to actually implement the variable in a firewall rule.

The 2.5.2 release notes just say that it’s there and point back to the redmine feature request. Am I missing something?
