4839,NAT corrupts mac addresses leading to packet loss -> Fixed in SVN,egwspiti,,"Attached are the output of ""ping www.virtualbox.org"" and  ""tcpdump icmp -s 0 -w icmp.log"" both executed at the guest OS. ping shows a significant packet loss, while tcpdump shows that all the icmp replies were received. however, the dst mac address of the icmp replies was quite random thus leading to packet loss. the current logs are from an INTEL PRO/1000 MT Server (the same happens with the default PCnet-FAST III)
