Using the Configuration Menu
If you have an FTP server that you wanted Internet users to
access by WAN port 2100 and only during the weekends, you
would need to enable it as such. FTP server is on LAN computer
192.168.0.30. FTP uses port 21, TCP.
Name: FTP Server
Private IP: 192.168.0.30
Protocol Type: TCP
Private Port: 21
Public Port: 2100
Schedule: From: 01:00AM to 01:00AM, Sat to Sun
All Internet users who want to access this FTP Server must connect to it from port
2100. This is an example of port redirection and can be useful in cases where there
are many of the same servers on the LAN network.

Using the Configuration Menu
Some applications require multiple connections, such as Internet gaming, video
conferences, Internet telephony and others. These applications have difficulties working
through NAT (Network Address Translation). Special Applications makes some of these
applications work with the DI-724U. If you need to run applications that require multiple
connections, specify the port normally associated with an application in the “Trigger Port”
field, select the protocol type as TCP or UDP, then enter the public ports associated
with the trigger port to open them for inbound traffic.
The DI-724U provides some predefined applications in the table on the bottom of the
web page. Select the application you want to use and enable it.
Note: Only one PC can use each Special Application tunnel.
Name:
Enter a name for the Special Application Rule, for example
Game App, which will help you identify the rule in the future.
You can also select from a list of common applications, and the
remaining configuration values will be filled in accordingly.
Trigger Port:
Enter the outgoing port or range of ports used by your application.
[6500-6700]
Trigger Type:
Select the outbound protocol used by your application. [Both]
Public Port:
Enter the port or range of ports that you want to open up to
Internet traffic. [6000-6200]
Public Type:
Select the protocol used by the Internet traffic coming back
into the router through the opened port range. [Both]

Using the Configuration Menu
Port Fowarding
Advanced > Port Fowarding
Multiple connections are required by some applications, such as internet games, video
conferencing, Internet telephony, and others. These applications have difficulties working
through NAT (Network Address Translation). The Port Forwarding section is used to open
multiple ports or a range of ports in your router and redirect data through those ports to a
single PC on your network. This feature allows you to enter ports in various formats.
Name:
Give the Port Forwarding entry a name that is meaningful to
you, for example Game Server. You can also select from a list of
popular games, and many of the remaining configuration values
will be filled in accordingly. However, you should check whether
the port values have changed since this list was created, and
you must fill in the IP address field.

UDP Ports to Open:
Enter the UDP ports to open. [6159-6180, 99]
Firewall Rule:

Using the Configuration Menu
Dynamic
Fragmentation:
This option should be enabled when you have a slow Internet
uplink. It helps to reduce the impact that large low priority network
packets can have on more urgent ones by breaking the large
packets into several smaller packets.
Automatic Uplink
Speed:
When enabled, this option causes the router to automatically
measure the useful uplink bandwidth each time the WAN
interface is re-established (after a reboot, for example).
Measured Uplink
Speed:
This is the uplink speed measured when the WAN interface was
last re-established. The value may be lower than that reported
by your ISP as it does not include all of the network protocol
overheads associated with your ISP’s network. Typically, this
figure will be between 87% and 91% of the stated uplink speed
for xDSL connections and around 5 kbps lower for cable network
connections.
Uplink Speed:
If Automatic Uplink Speed is disabled, this options allows you
to set the uplink speed manually. Uplink speed is the speed at
which data can be transferred from the router to your ISP. This
is determined by your ISP.
Connection Type:
By default, the router automatically determines whether
the underlying connection is an xDSL/Frame-relay network
or some other connection type (such as cable modem or
Ethernet), and it displays the result as Detected xDSL or
Frame Relay Network.
