Easy way to verify expression elements

Version 3

    With expression element it's possible to create complex IP address element, but the expression element itself doesn't have tool to verify what expression currently translates to. Luckily there's Network Details tool in the policy view which is the good way to verify that your expression matches the intended addresses:

     

    1. First create your expression

     

    2. When expression is ready, add it to rule in firewall policy and select correct firewall from the drop-down menu as without selecting correct engine, the alias elements won't get translated correctly:
