Bridged interface not getting input traffic.

I'm feeling a little alone on linux...

I got a VirtualBox machine whose bridged interface (to eth0) isn't getting traffic in. For example I ping 8.8.8.8. I got outbound traffic, but inbound traffic is not getting here.
I know is also a network problem :S, actually... I also got a really poor performance if I nat ( virtualbox-bridged-adapter-8021q-%3D-%5Bb%5Dridiculous-performance%5B-b%5D-838385/
IE:
Code:
Virtual:
ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

--- 8.8.8.8 ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 3007ms
Host:
tcpdump -n host 69.64.x6

Post the output of:

Code:
$ sudo ifconfig -a
This will help understand your bridge configuration.

Ok, I restarted the virtual machine and I started to ping the gw. I got
Code:
ping gw
gw arp: who has ip
vb arp: me at xx:xx:xx:xx:xx
....silence
So I'll rise a ticket to the switch guys, if I get no luck... any other ideas/suggestions?
