Port Range Forwarding
To forward a port, enter the information on each line for 
the criteria required.

wish to give the application. Each name can be up to 12 
characters.
Start~End  Port  Enter  the  number  or  range  of  port(s) 
used by the server or Internet applications. Check with the 
Internet application documentation for more information.

TCP, UDP, or Both.
To IP Address  For each application, enter the IP address 
of  the  computer running  the  specific  application.  If  you

Triggering
The  Port  Range  Triggering  screen  allows  the  Router  to 
watch  outgoing  data  for  specific  port  numbers.  The  IP 
address of the computer that sends the matching data is 
remembered by the Router, so that when the requested 
data returns through the Router, the data is pulled back 
to  the  proper  computer  by  way  of  IP  address  and  port 
mapping rules.

Port Range Triggering
Application  Name  Enter  the  application  name  of  the

and ending port numbers of the triggered port number 
range. Check with the Internet application documentation 
for the port number(s) needed.
Forwarded  Range  For  each  application,  enter  the 
starting  and  ending  port  numbers  of  the  forwarded 
port  number  range. Check  with  the  Internet  application

Applications and Gaming > DMZ
The  DMZ  feature  allows  one  network  computer  to  be 
exposed  to  the  Internet  for  use  of  a  special-purpose 
service  such  as  Internet  gaming  or  videoconferencing. 
DMZ hosting  forwards all  the  ports  at the  same  time to 
one PC. The Port Range Forwarding feature is more secure 
because it only opens the ports you want to have opened, 
while DMZ hosting opens all the ports of one computer, 
exposing the computer to the Internet. 
Applications and Gaming > DMZ
DMZ
Any computer whose port is being forwarded should have 
its DHCP client function disabled and have a new static IP 
address assigned to it because its IP address may change 
when using the DHCP function.
Enabled/Disabled  To  disable  DMZ  hosting,  select 
Disabled.  To  expose  one  PC,  select  Enabled.  Then 
configure the following settings:
Source IP Address  If you want any IP address to be the 
source, select Any IP Address. If you want to specify an IP 
address or range of IP addresses as the designated source, 
select and complete the IP address range fields.
Destination  If  you  want  to  specify  the  DMZ  host  by  IP 
address, select IP Address and enter the IP address in the 
field provided. If you want to specify the DMZ host by MAC 
address, select MAC Address and enter the MAC address 
in the field provided.
