WAN_DHCP6 gateway stuck pending with "Do not wait for RA" set
Added by Daryl Morse almost 2 years ago.

Plus Target Version:
22.05
Release Notes:
Force Exclusion
Description
My specific situation is the following:
ISP requires the following settings:
Request only an IPv6 prefix
Do not wait for a RA
WAN_DHCP6 is stuck pending / unknown indefinitely.
The file /tmp/hn0_defaultgwv6 is missing.
The ISP gateway address is link-local.
IPv6 is working, but DHCPv6 addresses are not being allocated.
This issue is discussed in https://forum.netgate.com/topic/170445/wan_dhcp6-pending-unknown-and-dhcpv6-server-not-working. This is possibly related to the M and O flags not being set in the RA message.
This issue does not exist in 2.6.0 and it was introduced into 2.7.0-DEVELOPMENT in the February 2022 time frame.
I am having the same issue in the development versions of 22.05. "Do not wait for RA" seems to be the culprit as well.

In my case, I'm pretty sure "do not wait for RA" is NOT the problem. With my ISP, if "do not wait for RA" was not working, there would be no IPv6 at all. However, IPv6 is working, except for dpinger not running and dhcpv6 not running. I suspect this is because of the missing gateway file.

I think I've spotted the problem here. In #6880 the scripts were changed around a bit and the withoutra path isn't getting the script header that should be setting the router file(s).
Try the attached patch and see if it helps for you.

Thank you for taking a look at this problem. I applied the patch. It fixed the problem of dpinger not starting, but dhcpv6 is still not starting up properly. Let me know if you need any info or log files from my systems.
- Subject changed from WAN_DHCP6 Stuck Pending / Unknown and DHCPv6 Not Working to WAN_DHCP6 gateway stuck pending with "Do not wait for RA" set
The dhcpd problem appears to be a regression from #12527 and is unrelated to this.
I have picked this back into the 22.05 branch and it will be included in the release.
- Status changed from Feedback to Resolved
Works on latest internal test snapshot.
