Issues with 22.03 DHCP

Clap · June 2, 2023, 11:39am

Currently using OpenWRT ver 22.03.5 on a 4gb raspberry-pi4b
I'm hoping someone is able to help me with why my DHCP isn't serving any leases to my lan... I have posted my settings below for my network,dhcp, and logs from dnsmasq on restart.

it appears to be capable of serving my guest network but not my lan (though the guest network will decide to lose internet capabilities while still being able to serve addresses)
(i have to manually set the address' on my pc to even access the router)

I have, stubby, bcp38, mwan3,sqm installed as well if those can cause conflicts (they didnt seem to have any conflicts prior to this update~. )

maybe due to:

I think dnsmasq restarting does that.

the interfaces appear to be active asfaik

config interface 'lan'
        option device 'br-lan'
        option proto 'static'

        option gateway '192.168.0.1'
        option broadcast '10.71.71.255'

The gateway here is wrong. Is this device the router or is there another gateway?

Clap · June 2, 2023, 1:33pm

The gateway has been corrected thank you so much for catching that, however the DHCP lease still refuses to function for the lan device I dont understand how the guest device has a dhcp lease but my lan is... not getting a lease

You have list interface ‘br-guest’ , you need list interface ‘br-lan’ too?

eduperez · June 2, 2023, 1:55pm

Perhaps because you instructed DNSMASQ to only serve a specific interface?

mk24 · June 2, 2023, 2:38pm

Yes either add br-lan to the list in the main config dnsmasq block or (preferably) remove any interface list-- which by default causes dnsmasq to listen on all interfaces (then e.g. for wan, it can be disabled with option ignore 1 or option dhcpvX disabled)

Clap · June 3, 2023, 12:32am

Thank you guys so much, that fixed the lease not being served!

I dont know how I even missed that, it used to automatically put the lan into the list prior to this update iirc.

Thanks again
