one more hint, the veth0[ab] needs some tuning...
here is the black magic generated by the external forwardization process on 
my side:

ip link add veth0a type veth peer name veth0
ip link set veth0 name veth0b
ip link set veth0a up multicast on promisc on mtu 8192
ethtool -K veth0a rx off
ethtool -K veth0a tx off
ethtool -K veth0a sg off
ethtool -K veth0a tso off
ethtool -K veth0a ufo off
ethtool -K veth0a gso off
ethtool -K veth0a gro off
ethtool -K veth0a lro off
ethtool -K veth0a rxvlan off
ethtool -K veth0a txvlan off
ethtool -K veth0a ntuple off
ethtool -K veth0a rxhash off
ethtool --set-eee veth0a eee off
ip link set veth0b up multicast on promisc on mtu 8192
ethtool -K veth0b rx off
ethtool -K veth0b tx off
ethtool -K veth0b sg off
ethtool -K veth0b tso off
ethtool -K veth0b ufo off
ethtool -K veth0b gso off
ethtool -K veth0b gro off
ethtool -K veth0b lro off
ethtool -K veth0b rxvlan off
ethtool -K veth0b txvlan off
ethtool -K veth0b ntuple off
ethtool -K veth0b rxhash off
ethtool --set-eee veth0b eee off
