This is not a dumb WLAN client. A WLAN client does ordinarily just have one MAC address (the address of the WLAN interface).
Thus you can't just bridge the WAN port with the WLAN client network. You either have to NAT the traffic or use WDS (3-address-mode) or
ARPNAT. Both WDS and ARPNAT are not standard-compliant and the access point needs to support it. Have a look at the Wiki for that.

If that's okay for you that's the easiest way to go. Use Multiwan if you want to use multiple networks.
