That was fast
thank your for the warm welcome,
i read through this document since yesterday and covered only the first 30 pages now because of not much time for read right until end of the month.
I think i need a practical start hand or step by step instruction for this configuration for better understanding some things on this totally new (and much more logical) gui and working sheme.
And this is the perfect practise thing for it.
so the goal is : all the machines should at the end in the same subnet wich is (192.168.124.0/24) with a dhcp and name server like dnsmasq for it does befor and reachable from the other net wich is 192.168.220.0/24
i assume i can reset the old network settings in the vm's??
