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 policies.
You can add multiple IP pools to any interface and select the IP pool to use when
configuring a firewall policy.
You can enter an IP address range using the following formats.
• x.x.x.x-x.x.x.x, for example 192.168.110.100-192.168.110.120
• x.x.x.[x-x], for example 192.168.110.[100-120]
