      I'm running pfSense 2.4.0-BETA in a Microsoft Hyper-V VM. Everything is working as expected except for IPv6.

      I get a 62 bit delegation from Comcast WAN (hn1) and I have a LAN (hn0) tracking prefix 0, a DMZ (hn2) tracking prefix 1 and a GUEST (hn3) tracking prefix 2. I purposely do not specify any DNS/subnet in DHCPv6/RA pages because I want pfSense to dynamically use the delegated interfaces subnet/IP.

      Yet every time I reboot I get the following errors in the log -> system -> routing:

      radvd no auto-selected prefix on interface hn0, disabling advertisements
      radvd no auto-selected prefix on interface hn2, disabling advertisements
      radvd no auto-selected prefix on interface hn3, disabling advertisements

      It's like the LAN, DMZ and GUEST interfaces are being initialized before the WAN, when Comcast PD hasn't happened yet.
      Infact, if I then go to status -> services and restart radvd everything starts working fine.

      Am I missing something or doing something wrong?

      Also, second problem: after RA starts working again I see the following errors in the log -> system -> routing:

      radvd received RS or RA with invalid hoplimit 1 from fe80::xxxx:xxxx:xxxx:xxx

      I have the RA set up as "Assisted" and these are all Windows clients trying to get either SLAAC or DHCPv6.

      Again, am I missing something or doing something wrong?
