RED: Notify of Duplicate Networks
While playing around with RED, we've recently had the problem that we accidently used a network 192.168.x.x/24 for the RED network that was already used for another VPN connection. That caused some trouble because we could not find why we did not get a connection through RED.
So it would be great if Astaro could implement a feature that checks if a network is already used somewhere (VPN, routing, etc.) and throws out a warning if someone uses it elsewhere.
