Doing some tests with Netscaler at the moment (input welcome!), and discovered that if you have a network offering with external LB, you're not allowed to specify the CIDR later when you add a network.
Instead it seems to randomly pick a range, from I don't know where, and use that. Does anyone know where this behaviour comes from? Why does CloudStack think it is better at specifying a proper CIDR than me? Where is it getting it's range from? The saga continues -- Erik
