Eicon Networks 2440 manual ‘Default NAT Server’ field

Page 54

In some cases, you may want to forward all datagrams containing unspecified protocols to a computer on your LAN. The Diva 2440 calls this computer the ‘default NAT server’.

To define a default NAT server, enter the IP address of the device that should receive these datagrams into the ‘Default NAT server’ field on the IP Parameters panel. (From the main menu, click ‘Advanced Configuration’, then ‘NAT Static Mappings’.

‘Default NAT Server’ field

Note: The Diva 2440 handles traffic with the following protocols: HTTP, Telnet, TFTP, ECHO (UDP port 7), and SNMP. Only traffic that does not contain these protocols will be forwarded to the default NAT server. To forward the aformentioned protocols you must define a NAT static mapping for each one.
