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.

Note: The Eicon 1530 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.
