Re: DHCP broken on WR741ND in Bridge mode

config dhcp 'lan'
option interface 'lan'
option start '100'
option limit '150'
option leasetime '12h'
option ignore '1'
Delete the "option ignore'1'" from the dhcp lan section

I don't have that in my config

---------------------
config interface 'lan'
option type 'bridge'
option proto 'static'
option netmask '255.255.255.0'
option ifname 'eth0 eth1'
option ipaddr '192.168.1.250'
option gateway '192.168.1.1'
option dns '192.168.1.1'
Change the line to: option ifname 'eth0 eth1 br-wan'

-----------------

The 2 changes above are the only 2 differences I see in the configs

Make those 2 changes via command line vi and then reboot

Then see if DHCP works.

It could be something with your main AP - what type of router
is your main Access Point?

For my setup the main AP = Asus RT-N16
:twisted: Soylent Green Is People! :twisted:
2x Asus RT-N16 = Asus 3.0.0.4.374.43 Merlin
2x Buffalo WZR-HP-G300NH V1 A0D0 = Gargoyle 1.9.x / LEDE 17.01.x
2x Engenius - ESR900 Stock 1.4.0 / OpenWRT Trunk 49400

Made the changes. Still no luck. No DHCP on lan clients over bridge. Main router is a VDSL ZTE ZXDSL 931 VII with Broadcom 6368 chipset.

You can try OpenWRT Attitude Adjustment 12.09 and see if you can
get that to work, but I suspect it may not.

Not enough info to say it's Gargoyle because I have it working on
my setup.

You would need to test off another access point to verify.

It could be a limitation on your main DSL modem/router.
