When you create a NAT static mapping, the Diva 2440 routes all traffic for the protocol you
specify to the designated computer. This includes traffic normally handled by the Diva 2440
itself. Only one computer on the internal LAN can be designated to receive the traffic for a
specific protocol. This means, for example, you cannot create multiple web servers; all web
traffic must be sent to one computer on your LAN.
Creating Static NAT Mappings
1.
Launch the web configuration interface.
2.
From the main menu, click ‘Advanced Settings’, then click ‘NAT Static Mappings’.
3.
For each server that you want to define, specify the following parameters:
• ‘Protocol’: The protocol that remote computers will use to access the server.
• ‘Server port’: The port number that the protocol will use on the server.
• ‘Server address’: The IP address of the computer that will act as the server. The
server address must be on the same LAN as the Diva 2440 (or must be reachable
via the LAN).
4.
Click ‘Save’.
Specifying a Default NAT Server
When the Diva 2440 receives incoming datagrams containing protocols it is not supposed to
accept, the datagrams are discarded. For example, if an incoming datagram contains an FTP
request, and no FTP server has been defined using a static mapping, th e datagram is
discarded.
