LAN set to Track IPv6 Interface WAN but no global IPv6 address on LAN

[gothbert]

Hi,

I had this working once but I am unsure if I screwed up the configuration or the update from 17.1.1 to 17.1.2 was the cause. I am now on 17.1.3.

Details:

Configuration in web interface is
WAN interface: Basic, Directly send SOLICIT, DHCPv6 Prefix Delegation size 64, Send IPv6 prefix hint
LAN interface: Track IPv6 Interface WAN, IPv6 Prefix ID 0

WAN interface gets 64bit prefix from upstream stateless DHCPv6 server:

Code: [Select]

inet6 2a02:908:x:x:x:x:x:f83 prefixlen 64 autoconf
LAN interface only has link-local address

Code: [Select]

inet6 fe80::1:1%em0 prefixlen 64 scopeid 0x1
LAN interface does not get an IPv6 address from the delegated prefix.

The following reports may or may not be related:

Any ideas other than filing an issue?

Best regards
