IP pools
An IP pool (also called a dynamic IP pool) is a range of IP addresses added to a
firewall interface. If you add IP pools to an interface, you can select Dynamic IP Pool
when you configure a policy with the destination set to this interface. You can add an
IP pool if you want to add NAT mode policies that translate source addresses to
addresses randomly selected from the IP pool rather than being limited to the IP
address of the destination interface.
If you add an IP pool to the internal interface, you can select Dynamic IP pool for
policies with the internal interface as the destination. For example, you can add IP
pools to External->Internal and DMZ->Internal policies.
You can add multiple IP pools to any interface but only the first IP pool is used by the
firewall.
This section describes:
• Adding an IP pool
• IP Pools for firewall policies that use fixed ports

The start IP and end IP must define the start and end of an address range. The start
IP must be lower than the end IP. The start IP and end IP must be on the same subnet
as the IP address of the interface that you are adding the IP pool.
