From Seth:

There is a problem where pfSense itself can not reach the ipv6 internet [with a DHCPv6 WAN] leading to issues with anything that attempts to load remote ipv6 content causing issues in dns, http etc. This could be the DHCP6 client setting the routes too strict, or the firewall rules itself on pfSense are too strict to get out. This might be specific to the dhcp6 client setup.

When I tried this, my WAN received a prefixlen of 128, not sure if that's related.

Split off from #2347

Make sure that we configure the track interface from the DHCP6 wan, correct typo.

A few launch improvements so that configuring the DHCP6 client on the WAN it immediately kicks in.
With the fixed rc.newwanipv6 it should immediately spring to life.

#1 Updated by Seth Mos about 8 years ago

Just tested a upgrade from a 2.0.2 VM to 2.1, configured WAN for DHCP6 and LAN as track, prefix id. 0
Does not bring up a DHCP6 address on the WAN or a prefix on the LAN.

Reboot the router with those settings and it comes up without issue. Maybe firewall rules for DHCP6 not being applied yet?

At some point this was fixed or some other change fixed it, as it still shows /128 prefix but it works fully now. A router behind a PD setup gets a DHCPv6 WAN IP and also has full IPv6 connectivity outbound.
