Network Address Translation (NAT)

CSD supports NAT. If a client’s address is an illegal address, or if a session is the result of another session originating from the client, the CSD will be used as a NAT machine. You use the NST table to configure NAT support. The NAT table includes the following fields:

NAT Status – Enables or disables the NAT feature.

NAT Address – The address that the CSD will assign to the client. The server will respond to this address, and the CSD will redirect the reply to the client’s original address. You can enter an array of up to seven addresses.

To enable/disable NAT:

From the CSD menu, choose NAT.
The NAT table appears.
From the NAT Status pull down list, choose the status.
Click Set.
The NAT status changes.

To enter a NAT address:

From the CSD menu, choose NAT.
The NAT table appears.
Click .
The NAT Table Insert window appears.

In the NAT table window, click .
The address(s) are added to the NAT address list.
