packets based on IP Address, Ports or Protocols. Packet filters perform these duties based on a set of configurable rules called Policies. Packet filtering is the original and the most basic type of firewalling and most routers provide packet filtering. Disadvantages of packet filtering however ...
This deep inspection can look at things like packet payloads and which application is being accessed by the packets. This allows the firewall to enforce more granular filtering rules.
