Maybe I'm just being stupid, but, having followed this how-to and got all my DomUs up fine I couldn't get them to network using the instructions on creating a NATted network.
Until I found http://wiki.kartbuilding.net/index.php/Xen_Networking
and I noticed the instructions for setting the netmask in the DomUs was different. The Howtoforge version says to set them as 255.0.0.0 whereas what worked from the Kartbuilding one linked to above was 255.255.255.0
Does that make sense? Is there just a typo in the Howtoforge version? Or must there be some other difference somewhere I've not noticed?
