Source	Select the source address from which users can access the server.
Destination	Select the virtual IP.
Schedule	Select a schedule as required.

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.

For example, if you add an IP pool to the internal interface, you can select Dynamic IP pool for Ext->Int policies.

You can add multiple IP pools to any interface but only the first IP pool is used by the firewall.
