Is the IP address of your router or your other machine? – Majenko May 27 '11 at 9:32

When running with Bridged mode networking it is as if the guest OS is a completely separate computer on the network and nothing at all do to with the Host OS.

You should treat the guest as if it were a separate computer and configure the networking accordingly.

The default gateway and DNS settings should point to your Internet router, not the host computer.

Better still, if your using DHCP on your network, use that to configure the guest automatically.
