Create Firewall Policies for Firewall Management in Nebula

A Firewall Policy consists of settings that govern the network traffic permitted on your endpoints. After reviewing your firewall rules and assigning them to Rule Groups, create a Firewall Policy to apply your Rule Groups to your endpoints based on their Nebula policy.
