Packet rules concepts

Packet rules comprise both network address translation (NAT) rules and IP filtering rules. These two rules run at the IP layer of the TCP/IP stack and help protect your system against potential risks that are commonly associated with TCP/IP traffic.

To better understand how packet rules work, you need to be familiar with the following concepts and how they apply to your system:
  • Packet rules versus other IBM® i security solutions
  • NAT
