> Chapter 9 - Firewall > Firewall objects > Addresses


Firewall addresses define sources and destinations of network traffic and are used when creating policies. When properly set up these firewall objects can be used with great flexibility to make the configuration of firewall policies simpler and more intuitive. The FortiGate unit compares the IP addresses contained in packet headers with a security policy’s source and destination addresses to determine if the security policy matches the traffic.

The addresses in the FortiGate unit can include:

  • IPv4 addresses
  • IPv6 addresses
  • IPv4 Address Groups
  • IPv6 Address Groups
  • IP Pools
  • Virtual IP Addresses
  • Geography based addresses
  • Wildcard addresses and netmasks
  • Fully Qualified Domain Name addresses
  • Multicast addresses
