Cloning MAC address to WAN

[Soler]

Hello, I'm having a problem cloning the MAC address to the WAN interface. Reason I would like to do so is because I have two routers while testing out Openwrt. When I switch routers, I would like to avoid resetting the cable modem each time whichi is in the basement.

I followed the following instructions in the open wrt faq:
To enable MAC address cloning in OpenWrt on the WAN interface you have to set the wan_hwaddr NVRAM variable.

nvram set wan_hwaddr="aa:bb:cc:dd:ee:ff"
nvram commit
After that reboot your Wrt router.

reboot
Now check the MAC address on the your WAN interface with the ifconfig command. Your WAN interface should have the MAC address which you set in the NVRAM variable above.

When I do a nvram get wan_hwaddr returns the MAC address I want but doing an ifconfig displays the original router MAC. Anyone get this to work?
