NAT Prerequisites

Before configuring NAT, verify that the following prerequisites have been met:

• A registered IP address has been obtained for each public interface on the server.
• TCP/IP has been enabled for and bound to two interface boards (the public and private interfaces).

  If your Novell BorderManager 3.7 installation was successful, this prerequisite has already been satisfied for at least one board.

• For interfaces that have TCP/IP enabled, IP packet forwarding has been enabled or static routing has been enabled to use a static routing table.

  To enable IP packet forwarding from the server console, load INETCFG, select Protocols > TCP/IP and change the status of IP Packet Forwarding from Disabled End Node to Enabled Router.

  To configure static routing from the server console, load INETCFG, select Protocols > TCP/IP, enable LAN Static Routing, and select LAN Static Routing Table to enter static routes.

• An Internet Service Provider (ISP) connection has been configured with enough bandwidth for the number of users on your network.

  If the Novell BorderManager 3.7 server does not provide the connection to the ISP, ensure that the server has a static route configured or that the router to the ISP is in the routing path of the Novell BorderManager 3.7 server.

NOTE:  It is assumed that all clients that will use the NAT-enabled interface as a default route to the Internet have already been configured with a TCP/IP stack and an IP address. The IP addresses can be registered or unregistered addresses.
