Uh.  So qemu can't be the culprit since it doesn't receive anything :)

So it's supposed to be using 10.0.2.3 I guess. Just to make sure, you
could try

/initrd/bin/nslookup www.google.com 10.0.2.3

Do you get output when pinging 10.0.2.3?
(you won't get ping answers, but that's fine, qemu should still be able
to see the requests coming in)

Also, just to make sure: you don't have firewalling rules, do you?
