[SOLVED] DHCP6 Gateway is shown as disconnected in 24.7

[Patrick M. Hausen]

One more hint, in CLI the WAN interface doesn't show any IPv6 address at all.

How exactly are you checking? ifconfig? With a common DTAG line the WAN interface is pppoe0.

Hi Franco, hi Patrick,

sorry for the confusing statement. ifconfig shows the automatically assigned and the VIP address in the CLI as described. The automatically assigned one is shown as detached.

What was meant was that after logging on to the CLI, only the IPv4 is displayed in the overview of interfaces for the WAN interface and no IPv6.

Incidentally, the gatway and the monitoring have been running stably since yesterday evening. However, I have not yet rebooted to see if this changes the configuration of the WAN_DHCP6 gateway.

Good morning,

I did a reboot meanwhile, the gateway settings are retained. gateway is shown online and the monitoring works. I'm still not sure, if this workaround with the VIP Ipv6 address in the gateway config is ok or not.

Also no idea why the automatic assigned IPv6 is detached, which maybe the reason that the gateway is offline / monitoring doesn't work.

If I can provide any logs let me know.

Stupid question:  Is patch 287c13beb still necessary to apply if one installs 24.7_9? 

I've been waiting a bit to upgrade to 24.7, but as I do a fair bit with IPv6, was watching this thread closely.  I'll probably be waiting a few more days before doing any installations anyway, but, wasn't sure if this patch is already included in one of the Hotfixes or not.

Not a stupid question. Yes, 287c13beb must be reinstalled, but I'm 95% sure it will be included in 24.7.1.

Since we have some kernel issues with FreeBSD 14.1 as is I'd recommend waiting for 24.7.1 which will ship a new kernel and getting confirmation that the upgrade path points to it as well as that will take a day more than the initial 24.7.1 release announcement and you can't see that from the upgrade changelog for technical reasons.


Cheers,
Franco

Is this still a known issue? I'm on 25.1.8 and have the same problem.
I get a static IPv4 address and IPv6 prefix from my provider.

My WAN settings:
IPv4 Configuration Type: PPPoE
IPv6 Configuration Type: DHCPv6
Request prefix only & Send prefix hint are both checked

Clients are able to connect to websites via IPv6 and my servers are reachable via IPv6 from the internet. Also IPv6 Ping via Interfaces > Diagnotics is working.

But if I want to Enable Gateway Monitoring the gateway is "Offline" and the Gateway monitor isn't starting with this error in the log:

Code Select Expand

/usr/local/etc/rc.syshook.d/monitor/20-recover: The required WAN_DHCP6 IPv6 interface address could not be found, skipping.

Routes are there:

Code Select Expand

ipv6 default fe80::ded2:fcff:fe24:dd60%pppoe0 UGS NaN 1492 pppoe0 WAN
ipv6 2606:4700:4700::1111 fe80::ded2:fcff:fe24:dd60%pppoe0 UGHS NaN 1492 pppoe0 WAN
I also tried the give the gateway an IPv6 address from within my prefix without luck. If I uncheck "Request prefix only" the gateway still gets an fe80 address.
