how can I define network groups like "any but some networks", to use for example in Firewall Rules and SNAT/DNAT configurations to exclude some networks?
Define a new Deffinition under Deffinition/networks add hosts or network seggments.
Make after this a new Deff. (Networkgroup) and put in the deffinition you've made before.
Now you can use them in rule's and Snat/Dnat rules.
