Linux ping virtual guest from host

I just need communication between host and virual pc, both on linux

HOST PC:Fedora 17 with Oracle Virtual Box

GUEST: Debian 6 with (apache 2, php 5.3)

Open VirtualBox Manager, select your guest, open settings -> Network and change:

1. Attached to from NAT to Bridge Adapter
2. select right name of host adapter (for me wlan0) whitch is connected to internet 

start virtual pc and try ping from host or from virtual ping host.

and for me virtual pc apache test
