Share 3G modem internet to an access point

hello, I recently installed OpenWRT on my raspberry pi, and I can successfully connect to internet with the 3G adapter (wwan0), but i can't share the connection using an access point (wlan0).
Could you help to solve it?

That exactly doesn't work?

Accessing the internet via your AP?

yes, i think there is no dhcp and that the wwan0 interface is not bridged properly

If you've set it up as a WAN when you created it, it should be ok.

DHCP is missing might be an active choice from openwrt, there is after all only one ethernet port.
