Xen users - Apr 2009 - domU and NAT

Hi All,

I managed to configure NAT on dom0 but this does not work properly.
Outgoing traffic from domU is seen with the original domU ip address
instead of the dom0 ip address and the requests can''t get back to the
domU.

ip_forward is enable (1)

Any hints?

Thanks,
Jan

I figured out MASQUERADING was not set.

The following rule needs to be set:

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE


Thanks,
