NAT
NAT (Network Address Translation) feature translates a private IP to a public IP, allowing multiple
users to access the Internet through a single IP account, sharing the single IP address. It is a natural
firewall for the private network.
Virtual Servers
In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program
(usually a server) incoming connections should be delivered to. Some ports have numbers that are
pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred
to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN (i.e. from other
machines on the Internet that are outside your local network), or any application that can accept
incoming connections (e.g. Peer-to-peer/P2P software such as instant messaging applications and
P2P file-sharing applications) and are using NAT (Network Address Translation), then you will
usually need to configure your router to forward these incoming connection attempts using specific
ports to the PC on your network running the application. You will also need to use port forwarding if
you want to host an online game server.
The reason for this is that when using NAT, your publicly accessible IP address will be used by and
point to your router, which then needs to deliver all traffic to the private IP addresses used by your
PCs. Please see the
WAN
configuration section of this manual for more information on NAT.
The device can be configured as a virtual server so that remote users accessing services such as
Web or FTP services via the public (WAN) IP address can be automatically redirected to local
servers in the LAN network. Depending on the requested service (TCP/UDP port number), the
device redirects the external service request to the appropriate server within the LAN network.
This part is only available when NAT is enabled.
Note:
The maximum number of entries: 64.

The following configuration page will appear to let you configure.
Interface:
select from the drop-down menu the interface you want the virtual server(s) to apply.
Server Name:
select the server name from the drop-down menu.
Custom Service:
It is a kind of service to let users customize the service they want. Enter the user-
defined service name here. It is a parameter only available when users select
Custom Service
in
the above parameter.
Server IP Address:
Enter your server IP Address here. User can select from the list box for quick
setup.
External Port
Start:
Enter a port number as the external starting number for the range you want to give
access to internal network.
End:
Enter a port number as the external ending number for the range you want to give
access to internal network.
Internal Port
Start:
Enter a port number as the internal staring number.
End:
Here it will generate automatically according to the End port number of External port
and can’t be modified.
Protocol:
select the protocol this service used: TCP/UDP, TCP, UDP.

Set up
1.
Select a Server Name from the drop-down menu, then the port will automatically appear, modify
some as you like, or you can just leave it as default. Remember to enter your server IP Address.

Press
Apply
to conform, and the items will be list in the

Remove
If you don’t need a specified Server, you can remove it. Check the check box beside the item you
want to remove, then press
Remove
, it will be OK.
ALG
The ALG Controls enable or disable protocols over application layer.

Port Triggering
Port triggering is a way to automate port forwarding with outbound traffic on predetermined ports
(‘triggering ports’), incoming ports are dynamically forwarded to the initiating host, while the
outbound ports are in use. Port triggering triggers can open an incoming port when a client on the
local network makes an outgoing connection on a predetermined port or a range of ports.
Click
Add
to add a port triggering rule.
Interface:
Select from the drop-down menu the interface you want the port triggering rules apply to.
Application:
Preinstalled applications or Custom Application user can customize the utility yourself.
Custom Application:
It is a kind of service to let users themselves customizes the service they
want. Enter the user-defined service name here.
Trigger Port
Start:
Enter a port number as the triggering port starting number.
End:
Enter a port number as the triggering port ending number.
Any port in the range delimited by the ‘Start’ and ‘End’ would be the trigger port.
