FOSDEM was great

Actually this solution works for up to XEN 3.1.3:
$IPTABLES -t raw -A PREROUTING -i xenbr0 -j NOTRACK
when you have a soho-xen-server and want to forward traffic to a domU in a NATed environment and bridged Xen
even when they are on the same subnet
Kudos goes to james Bulpin
and CONFIG_IP_NF_RAW =y in the kernel
Full forwarding to Xen guest
$IPTABLES -t nat -A PREROUTING -p tcp –dport 20000 -j DNAT –to 172.14.1.50:80
$IPTABLES -t raw -A PREROUTING -i xenbr0 -j NOTRACK
where 172.14.1.50 is the domU
