Adding policies with virtual IPs

Use the following procedure to add a policy that uses a virtual IP to forward packets.

To add a policy with a virtual IP

Go to Firewall > Policy.

Select the type of policy that you want to add.
• The source interface must match the interface selected in the External Interface

list.

• The destination interface must match the interface connected to the network with

the Map to IP address.

Use the following information to configure the policy.

Select OK to save the policy.

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.
