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
Save
. Leaving applications
enabled unnecessarily creates a security risk.

for this application. Use as many rows as necessary to define the required number of port
ranges. Unused rows can be left blank.
