WAN_DHCP6 pending / unknown and dhcpv6 server not working
-
@bimmerdriver I tried a past development release of 22.05 and had the exact same issue you are experiencing. Traffic flows without any issue but the gateway shows pending. I rolled back when I noticed the issue and haven't tried since.
I also have "Do not wait for a RA" and "Request only an IPv6 prefix" selected.

@bimmerdriver and @jimp I would also add that my Gateway / Monitor IP is an fe80, link-local, address. I swear I remember having this issue a year or so ago and it was resolved with an update.

In my situation, it has always been the case the gateway address is a link-local address. That does not cause a problem on 2.6.0 and it didn't cause a problem on 2.7.0 up to the point where this regression was introduced. As I pointed out above, I think this problem is related to the missing file /tmp/hn0_defaultgwv6.

I created a new bug in redmine, https://redmine.pfsense.org/issues/13238.
-
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.

The fix on #13238 fixed the gateway with "do not wait for RA"
The DHCPv6 daemon not running was a regression from https://redmine.pfsense.org/issues/12527 and it wasn't related to "do not wait for RA".
The attached patch here should fix the DHCPv6 daemon problem. It worked for me in my lab on several systems.
Fixes for both are going to be in 22.05.

@jimp Thank you! I haven't had a chance to try yet but I will in the next day or so if I can. Thanks again for your help!

I installed the second patch and I can confirm that it fixes the dhcpv6 problem.

@jimp I backed out both patches, then upgraded to the latest snapshot. Pleased to report that both issues are resolved. Thank you very much.

Wondering if those recent changes could somehow be related to rtsold not running, IPv6 WAN (DHCP) keeps losing connectivity
-
@luckman212 What version are you on? I believe this issue was specific to 22.05 / 2.7.0
-
@nedyah700 I'm on the latest 22.05 RC snapshot: 22.05.r.20220614.1944
