Description

Bug #4436 disable prefix delegation requests when no tracking interface is defined. This causes a regression in combination with Network Prefix Translation in a dual-WAN setup and a Unique Local Address range on the LAN interface: pfSense requests prefix delegation from both WAN interfaces, and uses NPT to perform translation for the ULA addresses on the LAN toward the respective delegated prefixes, e.g. for load balancing or failover purposes.

In the scenario, the prefix delegation on the WAN interfaces is required, but there is no tracking interface, because the LAN interface needs to be static IPv6 with the ULA addresses.

I have such a set-up, and upgrading from 2.2 tot 2.2.1 broke IPv6 for this reason.

Can we have more control over prefix delegation, so that we can re-enable it in scenarios like this one?
