My setup:

DSL Broadcom Atheros
LAN - OpenWrt - - - - wifi - - - OpenWrt2 - LAN
Wifi 192.168.1.1 192.168.2.1
aka 192.168.1.2 (to OpenWrt)

I have DHCP for both handled by OpenWrt, and wol on OpenWrt can wake hosts on both.

Basic setup:

OpenWrt

/etc/config/network lan section:

#### LAN configuration
config interface lan
        option type     bridge
        option ifname    "eth0.0"
        option proto    static
        option ipaddr    192.168.1.1
        option netmask    255.255.255.0

config route OpenWrt2
        option interface lan
        option target   192.168.2.0
        option netmask  255.255.255.0
        option gateway  192.168.1.2

/etc/config/dhcp lan section

config dhcp
        option interface    lan
        option start     100
        option limit    150
        option leasetime    12h
        # Give DHCP addresses to OpenWrt2 clients
        option 'options'        '-F lan,192.168.2.100,192.168.2.150,255.255.255.0,12h'

/etc/config/wireless is unchanged from original (AP mode, wds2).

OpenWrt2:

/etc/config/network lan and wan section:

config 'interface' 'lan'
        option 'type' 'bridge'
        option 'ifname' 'eth0.0'
        option 'proto' 'static'
        option 'ipaddr' '192.168.2.1'
        option 'netmask' '255.255.255.0'

config 'interface' 'wan'
        option 'ifname' 'eth0.1'
        option 'type' 'bridge'
        option 'proto' 'dhcp'
        option 'hostname' 'OpenWrt2'

/etc/config/wireless:

config wifi-device wifi0
        option type atheros
        option channel '2'
        option disabled '0'
    
config wifi-iface
        option device wifi0
        option network  wan
        option mode     sta
        option ssid     ssid
        option encryption       'psk2'
        option key      'key'

/etc/config/firewall:

config defaults
        option syn_flood    1
        option input        DROP 
        option output        ACCEPT 
        option forward        DROP 

config zone
        option name        lan
        option input    ACCEPT 
        option output    ACCEPT 
        option forward    ACCEPT
        option masq 1 

config zone
        option name        wan
        option input    ACCEPT 
        option output    ACCEPT 
        option forward    ACCEPT 
        option masq        1

DHCP is off:

/etc/init.d/dnsmasq disable

Two new files:

/etc/init.d/dhcrelay:

#!/bin/sh /etc/rc.common
# Copyright (C) 2006 OpenWrt.org
START=60

start () {
        dhcrelay -i br-lan -i br-wan OpenWrt
}

stop() {
        killall dhcrelay
        sleep 1
        killall -9 dhcrelay
}

/etc/init.d/udp-proxy: (for WOL proxy from OpenWrt when LAN host is connected to OpenWrt2)

#!/bin/sh /etc/rc.common
# Copyright (C) 2006 OpenWrt.org
START=50

start () {
        udp-proxy 40000 192.168.2.255
}

stop() {
        killall udp-proxy
        sleep 1
        killall -9 udp-proxy 
}

udp-proxy C program is available here http://www.vttoth.com/tunnel.htm

Hope this helps someone

sorry been a bit busy with the hurricane lately just got power back recently (I'm in Houston). Haven't tried upnpd but I think I need it for bittorrent. Interesting question will have to check...

Thanks you! Thanks you! Thank you! I have the same setup and have been having the hardest time finding out how to configure it correctly.

I did it with local dhcp(no dhcrelay), and without masq on second router.
