Description

I notice that configuring DHCP-PD starts a dhcpd server on the tracking (LAN) interface that serves up the delegated prefix; however, unlike for interfaces that are explicitly configured for DHCP, as far as I can see, no rules are added that would actually allow dhcp6 requests to pass on that interface. As a result, all my clients fall back to SLAAC.

I believe the problem is in /etc/inc/filter.inc:870:

$oc['track6-interface'] = $oc['track6-interface'];

This looks like a typo; looking at the surrounding code, it seems like the intention was for the destination to be $oic, not $oc.

The existing statement causes the 'track6-interface' entry to never be added to FilterIfList, which in turn causes the pass rules for DHCP6 traffic to not be added.
