Chapter 5 Network Configuration
Setting a Public NAT Address for the HD3000
NAT (Network Address Translation) is a protocol in which a LAN uses one set of
IP addresses for internal communication (within an organization's private LAN)
and a different, single address for communication with a public network, such as
the Internet. In this way, a NAT helps protect a LAN from exposure to unwanted
traffic.
To hide a LAN's users from other networks, the NAT maps the private addresses to
the public address. The public address is then used to identify the local users to
remote contacts. Therefore, remote contacts use this public address to call the local
users, without knowing their actual local addresses.
In the Advanced tab, you can enter the public address (if applicable) for your
HD3000.
To define the public address for the HD3000
In the NAT IP box, enter the public address used for contacting your
HD3000 device.
Enter the public
address for your
HD3000.
