Re: [Xen-users] Networking change in Xen unstable

["John Fairbairn" <webmaster@xxxxxxxxxxxx>]

Hello,
  i would think that all you would need to so if thats the error you get
is to enable ip forwarding in the dom0 kernel. Generally that is done
with

echo "1" > /proc/sys/net/ipv4/ip_forward

if memory serves, I believe you have to reboot for this to take effect.

 Hope this helps you out some.
