[Xen-users] Nat for ipv4 & bridge for Ipv6 - Configuration?

[Bernard Dufresne <bernard.duf@xxxxxxxxx>]

Hi, i use Xen 4.4 on Debian 8, i wonder how i can create a NAT for Ipv4 since i have one IPv4 ip & bridge for Ipv6 since i have plenty of them.

On my dom0, i d like private Ipv4 ips & public Ipv6 ips. Thank you. 

Please find below my configuration files that does not work for sure. Notice the ipv6 ips here are all private ones for testing.
