NAT (RFC 1631) is the translation of the IP address of a host in a packet, for example, the source
address of an outgoing packet, used within one network to a different IP address known within
another network.
Select Enable to activate Network Address Translation (NAT). Enable this feature 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.
Select this option to allow plug-and-play Internet access which means that 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.
If you activate NAT, select Enable in this field to prevent communication between subscribers. This
is the default selection.
Select Disable, to deactivate layer 2 security and allow communication between subscribers.
Use this field to set the function of the Console port on the front panel of the VSG.
