NAT
Network Address Translation (NAT) is a standard method of mapping multiple
"internal" IP addresses to one "external" IP address on devices at the edge of a
network. For the OD200, the internal (local) IP addresses are the IP addresses
assigned to local PCs by the DHCP server, and the external IP address is the IP
address assigned to the WiMAX interface.
Virtual Server
Using the NAT Virtual Server feature, remote users can access different servers on
your local network using your single public IP address.
Remote users accessing services such as web or FTP at your local site thorugh
your public IP address, are redirected (mapped) to other local server IP addresses
and TCP/UDP port numbers. For example, if you set Type/Public Port to TCP/80
(HTTP or web) and the Private IP/Port to 192.168.7.9/80, then all HTTP requests
from outside users forwarded to 192.168.7.9 on port 80. Therefore, by just using
your external IP address provided by your ISP, Internet users can access the
services they need at the local addresses to which you redirect them.
