the correct MAC Address by typing
ipconfig/all
in the Command Prompt
for Windows OS. The MAC Address should be in the format of
00:11:22:33:44:55
Note: If you change the range of the Default LAN IP from 10.1.1.254 to 192.168.1.254,
the DHCP Server will change the DHCP Start IP address to 192.168.1.1 and DHCP End IP
address to 192.168.1.5 accordingly.
Networking - Forwarding
Port Forwarding helps you to open up a
Port
in the MF-230 so that support certain
Online Games, Host a Web Server or FTP Server, and etc.
WAN Port
It shows the range of Ports for incoming data from the router’s
Public IP; should it be Open for the Port Forwarding rule.
Server IP
It shows which computer is connected to the router’s Server IP
Address for Port Forwarding.
LAN Port
This is the range of Ports that the incoming data should be
forwarded to on the LAN Side.
Protocol
The Internet Protocol that is allowed to be Port Forwarded in the
Incoming data of the WAN Side.

Apply
To Save the Port Forwarding Rule or to Save the changes that
has been done. After this, you will need to reboot the router.
Troubleshooting:
If you are not able to set Port Forwarding or make it works:
•
Make sure the Port Forwarding range in both “WAN” and “LAN” is not more or
equal to 900. For example the range must be 30000 to 30899, and not 30000 to
30900.
•
Make sure the intended computer IP for the Port Forwarding on the LAN Side is
the same IP as you set in the Web GUI
Server IP Address
•
Make sure that the intended computer has turned off any Firewall programs and
allow the Ports that have been set in the router Port Forwarding rule.
•
A Port can only be used by ONE program at a time. This means that you can only
use Port 500 on ONE computer on the router at a time. Using Port 500 on two
computers at the same time would violate the ONE program rule, and your data
would get messed up.
•
Make sure you know and set the correct Ports for “WAN” and “LAN” in your Port
Forwarding rules as this is always the common mistake.

Networking – Trigger
Port Triggering is Port Forwarding with an ON/OFF switch for the Ports that have been
forwarded. This ON/OFF switch is turned ON or OFF by data flowing out of a Trigger Port.
Port Triggering is a little more secured than Port Forwarding because the incoming Ports
are not open all the time. They are only open when a program is actively using the
Trigger Port.
Note: Most Port Triggering setups DO NOT require you to enter a LAN IP Address
to forward the incoming Ports to. This means that any computer on the network
can use your Port Triggering setup. If two computers try to use the Port
Triggering setup at the same time you will run into problems.
Name
It is an Identifier of the Port Triggering rule.
Trigger
Port
It is the range of Ports that will be triggered ON/OFF when there
is outgoing data that uses that range of Ports from your router’s
Public IP side.
Open Port
It is the range of Ports that incoming data will be forwarded to
when outgoing data triggers the Port Triggering rule in the
router.
Trigger
Protocol
It is the Internet Protocol that is allowed to be Port Forwarded in
the Incoming data of the WAN Side.

Troubleshooting:
•
Make sure that the intended computer has turned OFF any Firewall programs
and allow the Ports that have been set in the router’s Port Triggering rule.
•
A Port can only be used by one program at a time. This means that you can only
use Port 500 on one computer with the router at a time. Using Port 500 on two
computers at the same time would violate the one program rule, and your data
would get messed up.
•
Make sure you know and set the correct Ports for “Triggering Port” and
“Forwarding Port” in your Port Triggering rule as this is always the common
mistake.
•
The Port that you set for Port Triggering is constantly sending data out to WAN.
The length of time that the router keeps those Ports open needs to be taken into
account. If the router times out between the gaps of outgoing data to WAN, the
Port Forwarding connection will be severed.
EXAMPLE: What happens when you are trying to download a very large file? The router
that you have set up with Port Triggering may not keep sending data out of the trigger
Port. When that happens, the router closes the incoming Ports, and your download is
interrupted.

Networking - DDNS
Dynamic Domain Name Server (DDNS) allows you to create a host name that points to
your Dynamic Public IP or Static Public IP address or URL.
Settings:
•
Tick on the “Enable DDNS” to enable this feature.
•
On the “Service Provider” column, select the DDNS Service Provider Name that
you sign up for in this service.
•
Create an account with any service provider from the drop down list.
•
Create and customize your own host name and select the domain name of your
choice from the service provider.
•
The correct setting at MF-230 is as the screenshot below
•
Host Name setting should be the customize name like “testing” or “johnnie” or
“June”.
It should be followed by a “.” (dot) like “webhop” or “dyndns” or
“homelinux” that have to be chosen from the service providers.
•
Domain Name setting is the end of chosen domain from the website like “com”
or “net” or “org” or “cc”
•
You will also have to key in the username and password of your account on the
service provider at the MF-230 username and password field.
•
Click “Apply” and reboot your router to save the changes.
