Connect your Router with your WAN-Router Device (modem, switch, ... )
root@OpenWrt:~# opkg update
root@OpenWrt:~# opkg install relayd

root@OpenWrt:~# opkg install luci-proto-relay
root@OpenWrt:~# opkg install wpad

root@OpenWrt:~# /etc/init.d/relayd enable

set ip Address of the LAN to something different
root@OpenWrt:/etc/config vi network
config interface lan
        option ifname   eth0
        option type     bridge
        option proto    static
        option ipaddr   10.0.1.1 
        option netmask  255.255.255.0

Connect to Luci with your browser to 10.0.1.1


Go to network, wifi make a scan

Create a new Interface "stabridge" in the Interface section.
use the "relay bridge" protocol

Relay between networks WWAN and LAN.

check
lan/wwan is set to IP address in a different net
interface stabridge is set to relay between lan/eth0 and wwan/wlan0
wlan0/wwan is interface is assigned

change Firewall rules
