I asked this question in a different way in another topic query. Here I am going to try again with different wording.
This is a synopsis of the successful scenario I implemented using two DD-WRT firmware routers.
Router 1 DD-WRT) WiFi Access Point 192.168.1 11 wired to ...
Router 2 DD-WRT) WiFi Client Bridge 192.168.1.1 (with local DHCP serving 192.168.1.etc) and is a wireless client on the wan side (192.168.0.2) of
Router 3) 192.168.0.1, a WiFi router that is connected to the internet.
The Client Bridge DD-WRT set up on Router 2 is a snap though the DD-WRT web GUI interface. Under the thumb of OpenWrt I cannot for the life of me figure out how to build Router 2 and bridge 192.1.1.etc to 188.8.131.52
P.S. I would revert to DD-WRT but OpenWrt has screwed me on that too.
