Port Forwarding

The Port Forwarding feature allows incoming traffic (from the Internet) to be forwarded to a

particular computer or device on the MiFi 4620L's wireless network. Normally, incoming traffic from

the Internet is blocked.

You need to use Port Forwarding to allow Internet users to access any server you are running on

your computer, such as a Web server, FTP server, or E-mail server. Also, for some online games, Port

Forwarding must be used for the game to function correctly. The Port Forwarding screen has the

following sections:

•

Port Forwarding

(See

Port Forwarding

on page 77.)

•

Custom Applications

(See

Custom Applications

on page 78.)

•

DMZ

(See

DMZ

on page 79.)

Port Forwarding

The Port Forwarding feature forwards incoming traffic from the internet to a particular connected

device. To use any of the common server applications listed, follow these steps:

➊

Select the

Enable Port Forwarding

check box.

➋

On the Port Forwarding section of the Port Forwarding screen, type the computer's IP

Address in the

IP Address of Connected Device

field beside the

Application

name.

➌

Enable the corresponding

Application

on this screen by selecting its check box.

➍

Save your changes by clicking

Save

.

Tell the person or company that needs port forwarding to connect to the MiFi 4620L's IP address (by

default, this is

http://admin.mifi

or

). Connection requests are forwarded to the IP

address specified in step 3.

IMPORTANT

When no longer needed, Port Forwarding should be disabled on this screen

by de-selecting its check box, and saving change(s) by clicking

. Leaving applications

enabled unnecessarily creates a security risk.

incoming traffic on that port range.

•

Destination IP Address

incoming traffic to be forwarded.

79

Port Ranges

You can define up to six port ranges for each application. Each port range has the following options:

•

Start Port

— Type the beginning of the range of port numbers used by outgoing traffic

for this application. Use as many rows as necessary to define the required number of port

ranges. Unused rows can be left blank.

•

End Port

— Type the end of the range of port numbers. If the port is a single port instead of a

range, type the same value for both the Start Port and the End Port.

•

Protocol

— For each port range (each row), select the protocol (TCP, UDP, or both) used by

that port range.

You can define all of your applications before you click

to save your changes. Use the

Ports

and

Hide

links as necessary to open and close the Port Definition Panel so you can define the ports for

each application as needed.
