1. EXPLANATION
1.1. IP Network and Address
The IP networks the NX-300 can use include Local Area Networks (LAN) used in small-scale areas, such as
within or on the premises of a company, and the Internet, which covers a wide area over remote distances.
LANs differ from the Internet in the IP address to be used.
Local IP address (private IP address): This address is used and can be freely set within the LAN.
Global IP address: This is the only address that is used to access the Internet.
To use the unit through the nternet fixed global addresses
must be acquired and assigned to it or the router if it is used.
hen a connection is made from nit to nit in the figure the local address can be used. o ever hen
a connection is made from Unit C to Unit A, the global IP address must be used.
The fixed global address must be assigned to the units connected via the nternet.
Consult with network management personnel or the ISP (Internet service provider) concerning the acquisition
of a fixed global address.
