I hate to be the first to say "works for me", but it does! :)

I have (or have had) many VMs in Virtualbox, both Windoze and various
flavors of Linux, as well as one or two other things. I always set
them up as bridged and they "just" work.

Can't think of what might cause it, but you might want to look at
/var/log/messages, etc., on both the guest and the host. Make sure
the vbox kernel module(s) is(are) installed. I don't think the vbox
tools for the client would have anything to do with this, but it won't
hurt to check that they are properly installed.

Good luck!
