<br>
The ping problem may be a routing problem on your host. Check if
the host has ip_forwarding enabled such that the host forwards
packages between "eth0" and "br0", that is between the bridge and
your host's physical nic. If this does not help, investigate your
routing tables and try to track your ping's package flow with
tcpdump.<div class="im"><br>
