10.3 Port Forwarding Screen

Use this screen to forward incoming service requests to the server(s) on your local network and set a
default server. You may enter a single port number or a range of port numbers to be forwarded, and the
local IP address of the desired server. The port number identifies a service; for example, web service is on
port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support
more than one service (for example both FTP and web service), it might be better to specify a range of
port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request that does
not have a server explicitly designated for it is forwarded to the default server. If the default is not
defined, the service request is simply discarded.

DESCRIPTION
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).
Select Enable to activate NAT. Select Disable to turn it off.
NAT loopback allows local users to use a domain name to access a server on the local
network. A packet sent to the public (WAN) IP address is always forwarded to the default
gateway (the LTE Device). With NAT loopback enabled, the LTE Device uses the WAN
interface's IP address as the packet's source address and treats the packet as if it came
from the WAN interface. The packet then can be forwarded to the local server according
to the port forwarding rule.
Select Enable to activate NAT loopback. Select Disable to turn it off.
Click Cancel to begin configuring this screen afresh.
Click Apply to save your changes back to the LTE Device.
