Problems with bridged network

[fratermine]

Hi everyone I have recently installed virtual box 4.0
I have Windows 7 guest o.s. and Ubuntu 10.10 host o.s.
I selected bridged network as networking mode
ubuntu receives an ip address like it's in the LAN like the host o.s. but i can't ping eth0 on ubuntu and i can't ping network adapter on windows
Do you know someone where is the problem?
thank you

You profile has Windows as host and Ubuntu as guest but you state the reverse here.
If the host is Windows check for firewall issues. If the host is Ubuntu then post the results of ifconfig -a from the Ubuntu terminal as well as ipconfig /all from the Windows command window.

Hi Perry
you are right
i have windows 7 hosts and ubuntu 10.10 guest
so i don't need to install a bridge on ubuntu using bridge utilities?
from windows i can ping ubuntu with no problem!
i will see for firewall
thanks
