Hello,
when I try to configure the DHCP server in LUCI under Network / Network Interfaces / LAN Interface / Edit / DHCP Server, the setup fails with the following error:
See the Attachment.
My OpenWRT version is "openwrt-24.10".
What else can I do?
I don’t read f
German, but let’s simply look at the config.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):

There are a ton of issues in your config -- it doesn't look like proper (official) OpenWrt syntax. Did this really come from openwrt.org? And why are you using a snapshot?
My recommendations:
- Install a proper stable release version (current stable: 24.10.4)
- Reset your config to defaults and start from scratch. As I mentioned, there are many things that are incorrect here, and it will take longer to fix the problems than to start over.
Meanwhile, I think your problem is here:
Specifically, the ra_lifetime line has an = sign which should not be there.
But... aside from that, there are major issues that are best addressed with a fresh start.
Does this mean I need to download a basic system with the necessary packages from the following website? https://firmware-selector.openwrt.org/?version=24.10.2
Okay, I know my IPv6 configuration is faulty. This is a new topic for me. Do I then have to recreate the entire network and firewall rule configuration?
Yes, that's the best way... but please be sure to get 24.10.4.
If you have any packages that you need installed, you can build a custom image that contains them, or you can install them after you write the image to your disk.
Yes, it would be a good idea to re-create it. You don't need to use bridge-VLANs when you are dealing with individually routed ports. Instead, you can use direct dotted notation (i.e. eth0.100).
I didn't look at your firewall config, so I don't know if there are any complex rules there, but given the nature of the issues in your current config, probably best to start over.
Pro-tip: add just one additional network (along with the associated DHCP and firewall configs), and test it at that point. You're also welcome to request a review to ensure you've done it correctly. If there are any issues, it will be much easier and faster to fix just one network than to worry about what looks like literally a dozen in your config above. Then, you take the syntax and use that as your recipe for all of the others.
