with director2 (xdp) up and director1 (dpdk) down...

from router machine they use the correct ip source (192.168.50.2)... but i see gue encapsulation arriving on router...

root@router:/var/log# tshark -ni ens7  port not 22 and not arp and port not 547 and not stp  and not icmp
Running as user "root" and group "root". This could be dangerous.

i've found... is because libvirt create there vm with default gateway on the ssh part of vagrant, and all network are nat network with dhcp... the first ip of each network can route traffic...
with my pull request her #105 they resolve the problem.
