Description

I have a 6rd connection over PPPoE to CenturyLink. I have IPv6 configured on LAN interface to track the WAN, plus 4 (out of 6 total) VLANs are configured to track the WAN. After rebooting, none of the internal interfaces have an IPv6 address assigned.

However, I always have a valid IPv4 and IPv6 address assigned on WAN. I can ping out from pfSense to both IPv4 and IPv6 addresses.

It seems that all I have to do to restore IPv6 connectivity on the internal interfaces is "Save" and "Apply" the WAN interface settings (without making any changes). There seems to be a variety of related problem reports online, none of which seem to have consistent symptoms or solutions. For example:

Reviewing my 'system.log', it seems the internal interfaces are configured early, before the PPPoE.

I found a condition in interface_6rd_configure() that prevents re-configuration while the system is still booting.

        /* configure dependent interfaces */
        if (!platform_booting()) {
                link_interface_to_track6($interface, "update");
        }

If I remove the platform_booting() condition such that link_interface_to_track6() is called at boot time, then rc.newwanip assigns the internal interface IPv6 addresses:

Probably my change is not ideal for all configurations, but hopefully this is a solid data point. I see no downsides in the logs or the system functionality. I'm willing to test variations if a more general solution exists.
