example, the source address of an outgoing packet, used within one network to a
different IP address known within another network.

to set your VSG to map multiple local IP addresses to one global IP address. This
is the default selection.
Select Disable to deactivate NAT.

subscribers do not have to change their network settings. This feature is activated
by default.

Select this option to assign private IP address to a network device (such as the e-
mail server). NAT will translate the private IP address to the public IP address on
the WAN.

Select Unlimited to allow each user to use any number of sessions at a time.
