I have firmware version 1.7.5.6-5 loaded into my ASUS WL-500b and switched into "Client Mode" (for accessing to internet provided by Wi-Fi) by this commands:

nvram set 13_x_ClientMode=1
nvram set 13_x_IBSS=1
nvram commit

All works fine, but I cannot get packets from internet through Wi-Fi to my computers.
My questions are:
1. Supports firmware 1.7.5.6-5 "Port forwarding" from Wi-Fi to LAN?
2. Supports firmware 1.8.1.9 "client mode", so I can use it as device for Internet from Wi-Fi?

Thanx
