I am running PPPoE over VLAN 6 for KPN FTTH in the Netherlands.
When looking at my "WAN" interface, I see that my MTU is set to 1508.
Under Devices → Point-to-Point → PPPoE, no MTU is set.
Under Interfaces → Overview, IGC0 (my physical NIC) shows an MTU of 1512.

I remember that at some point I had to add the physical adapter to the interfaces and set the MTU to 1512.
Was that in version 23.7?

Current output of http://pmtud.enslaves.us/
No IPv6 connectivity to http://pmtud.enslaves.us/ ! (tested at 2 locations)
Yesterday IPv6 MTU was looking ok!

Everything seems clear to me now! Thanks for the awesome support!

According to the documentation, "Identity Association" allows manual configuration. I will try that later.

Identity Association offers similar functionality like Track Interface (legacy), but without automatic ISC-DHCPv6 and Radvd configuration. It is intended for pure RA and DHCPv6 configuration using Dnsmasq or Kea/Radvd.

See the attached screenshot for the LAN settings.
I thought that when "Manual configuration" is turned off, only radvd distributes IPv6 addresses.

I am assigned a /48 prefix by my ISP.

That's why I saw that a prefix was delegated.
I'm also looking into switching to Kea or dnsmasq in the near future.

When looking in "Services - ISC DHCPv6 - Leases - Delegated Prefixes", I noticed that a prefix had been delegated.
My LAN interface is tracking the WAN interface with prefix ID "AAAA", with manual configuration turned off.

When checking /var/log/dhcpd/latest.log, I saw the delegated prefix as shown below:

How is it possible that a prefix is delegated when all related options are turned off?
The device requesting the prefix is a hardware Globalping probe.

Looks like that is working!

Thanks.

Having the same issue with the mobile view of the dashboard.

See attached screenshots.
1 menu invisible, 2 after some clicking around found the menu butten.

I am not having any troubles with the temprature.
Only posting this because Patrick asked.

Running Intel4 after running Intel3 for 1.5 weeks.
No issues so far!

Running ICMP2 kernel for 22 hours now and not seeing any reconnect from the Chromecast!
I think my Chromecast is the problem.

With icmp2 kernel i see multiple reconnects of a google chromecast "google tv" in my unifi dashboard.

Running kernel pf4 for a while now. And it looks like the reconnects are gone.

Maybe the reverts are the best for 24.7.2

Ship the fix!

And a Confirmation from my side as well!

Windows 11 pro traceroute via IPv6 AND IPv4 is working fine!

Great!

Can't help you with that.
But if more testing is needed today i can help.
