Do the Ethernet WAN & LAN ports on the Airport Express work to pass through an Internet connection even when the AirPort Express itself is shut down?

I have a cable modem with a single Ethernet port, which can be used to connect it to either a computer or a WiFi router, such as the AirPort Express. Thus if the modem is connected to a wireless router and an Ethernet connection to a computer is also desired, the latter must be connected to the Ethernet LAN port on the wireless router, which passes through the Ethernet WAN connection from the modem. I want to be able to turn off the wireless router when I don't need WiFi, but still have the computer connected to the Internet via Ethernet. Some wireless routers pass the connection from their Ethernet WAN port (connection from a modem) through to the Ethernet LAN port even when the device is itself not running. Is this true of the AirPort Express?
