Turn PirateBox to Access Point

Hi.

I've made a PirateBox with MR3040 and customized OpenWrt image.

My PirateBox itself can connect to Internet. I can ping websites and get their real IP address from PirateBox shell. But the devices that connected to PirateBox can't reach to the Internet.

Is it possible to use PirateBox as an access point? What I mean is sometimes I just want to plug an ethernet cable to my MR3040 and turn that connection to wireless. I don't want to reach piratebox.lan I want to reach the Internet. (I'd be verry happy if both works in the same time but my priority is connecting to Internet).
