Br-lan.10 stopped working

Installing and Using OpenWrt

I am wondering why my br-lan.10 stopped working, no internet connection from the related wifi and ping to 8.8.8.8 fails.

Other wifi and netowork work just fine.

From and eth cable on a lan port og my ex8300

 ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
92 bytes from 192.168.10.1: Destination Port Unreachable

connecting to the br-lan.10 lan

Well usually our standard question is as always!

What did you do just before it stopped working? Or more precise, what did you do between the last dhcp address change and when it stopped working?

Or to speed up the process, give us your network and dhcp config file!

So what i did before it started to break is to do a TimeMachineBackup to my nixos server where I also host the pihole.

OpenWRT its on an ea8300

this is my dhcp:

root@OpenWrt:~# cat /etc/config/dhcp

	option domainneeded '1'
	option boguspriv '1'
	option filterwin2k '0'
	option localise_queries '1'

Let’s see your complete 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:
grafik
Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

If this is a /24 network, this is invalid. The limit is too high. Max of 155 here.

Guys, I figure it out with your hints!

I did a mistake of naming the interface 10lan in network and lan in dhcp.

it bothered me that lan is at the end :smiley:
