Hi there,
I have opened config.xml and am wondering what this actually means:
<opnsense>
<system>
...
<ipv6allow>1</ipv6allow>
...
Obviously it will allow ipv6. But I'm really not sure where to find it in the gui or what it actually does.
I'm asking because I recently ran into this problem:
https://forum.opnsense.org/index.php?topic=38631.msg189107#msg189107
(tl;dr Default gateway for IPv4 disappeared after upgrade)
Also in System: Gateways: Configuration this appeared:

and could not be deleted for some reason. After clicking on bin icon, it just did nothing.
After a week it happened again randomly after a reboot.
So I decided to compare my config.xml with the default one.
One of the many differences in my config was<ipv6allow>1</ipv6allow> and I am not sure if this could be related to the problem.
I also find this overflow in my config:
<gateways>
<gateway_item/>
</gateways>
So I deleted it. And the undeletable undefined gateway disappeared.
Not sure if my problems are solved now or if it could happen again. Also not sure if its a bug in opnsense 24.1 or if I am just dumb bfu.
Thanks everyone for any advice!

This will enable pf to process IPv6 traffic.
Related setting in GUI is Firewall>Settings>Advanced>Allow IPv6.
