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!

oh, my IPv4 Upstream Gateway on LAN is (and can only be) set to Auto-detect.
I guess this is what you mean by Auto-config and everything is now set correctly.
Thanks for your help!

You might also want to have a look at the gateway config in the WAN interface, being set to Auto-Config.

Could you please tell me where I can find these settings?
I went to Interfaces > [WAN] but I couldn't find an item to set to Auto-Config.

Thanks in advance for your help.
