I’ve just completed this tutorial on creating basic rules within Check Point Smart Dashboard. We will run through creating a network object, adding NAT to it, adding a rule to allow our network object access to the external network. We will then create an object for a windows server that will allow us to PAT remote dekstop through to it. We will verify our rules in SmartView Tracker by viewing the allowed traffic.
