Hi Melanie, Yes looks like a UI bug. I tried through the UI with the browser in developer mode to see what was sent. The guest netmask is missing.

Creating an isolated network with CloudMonkey works perfectly using the syntax: create network displaytext=deleteme-cloudmonkey name=deleteme-cloudmonkey networkofferingid=<id> zoneid=<id> projectid=<id> gateway=172.17.1.1 netmask=255.255.252.0 networkdomain=deleteme-cloudmonkey.heinlein-intern.de Could this be a bug with 4.11? Can someone reproduce this behaviour?
