Access to IPv6 link-local stopped working with 24.7

Hi!
I updated today from 24.1.10 to 24.7.1. At a first glance everything worked smooth and I was happy and very pleased.
But it turned out that with release 24.7 I was no longer able to get any connectivity to IPv6 link-local addresses from the OPNsense box itself. I can not ping, telnet or access any IPv6 link-local address on my network. I require IPv6 link-local addresses for several services e.g. HAProxy as I use "Track IPv6 Interface" on all interfaces on my OPNsense box that's why I don't want to deal with changing prefixes.
In the live view of firewall logs I can see the packages pass (ICMP and telnet to port) but I don't get any response back. Ping from a Windows machine to an IPv6 link-local address works with not problem.
I am not sure if I missed something in the release notes and I am not an IPv6 expert. It just worked in the past.
Any help is really appreciated!
Attached you can find some screenshots.
Thanks and best regards
Ingo

You are using the proper scope id with these addresses? E.g. fe80::dead:beef:dead:beef%igb0?

For ping I certainly did. Besides this I never cared about the scope in link-local. Shouldn't it work without scope
Are you able to ping a IPv6 link-local address on your network? Than there must be something wrong in my setup

That is not entirely the same thing. Try this:
Code:
[Select]
ping6 fe80::9209:d0ff:fe25:7309%igb1
This is different from your:
Code:
[Select]
ping6 -I igb1 fe80::9209:d0ff:fe25:7309
Link-local addresses are not well suited for use with DNS names. Either use GUAs or ULAs for that.
