I would like to know how I could make Backtrack act as an access point for wireless connections and cable.

Scenario:
I am connected to a wireless network with the computer with BT5. I want to share that network with other computers without or with wireless nic. In my usage it will be both.

I have tried to setup an AP with Gerix Wifi cracker but those a fake APs that don't work properly.

And if this can be done can I add filters that will not allow facebook to be accessed and maybe bandwith limiter etc?

Help appriciated
