Share Local Resources in the Internet by Virtual

Server

When you build up a server in the local network and want to share it on the Internet,

Virtual Server can realize the service and provide it to the Internet users. At the same

time virtual server can keep the local network safe as other services are still invisible

from the Internet.

Virtual server can be used for setting up public services in your local network, such as

HTTP, FTP, DNS, POP3/SMTP and Telnet. Different service uses different service port.

Port 80 is used in HTTP service, port 21 in FTP service, port 25 in SMTP service and port

110 in POP3 service. Please verify the service port number before the configuration

.

friends through the Internet.

For example

, the personal website has been built in my home PC

(192.168.1.100). I hope that my friends in the Internet can visit

my website in some way. The PC is connected to the modem

router with the WAN IP address 218.18.232.154.

Tips:

1.

It is recommended to keep the default settings of

if you

are not clear about which port and protocol to use.

2. If the service you want to use is not in the

, you can enter the

corresponding parameters manually. You should verify the port number that the

service needs.

3.

You can add multiple virtual server rules if you want to provide several services in a

modem router. Please note that the

Users in the Internet can enter

Tips:

1. WAN IP should be a public IP address. For the WAN IP is assigned dynamically by

ISP, it is recommended to apply and register a domain name for the WAN by DDNS,

Open Ports Dynamically by Port Triggering

Port triggering can specify a triggering port and its corresponding external ports. When

a host in the local network initiates a connection to the triggering port, all the external

ports will be opened for subsequent connections. The modem router can record the IP

address of the host. When the data from the Internet return to the external ports, the

modem router can forward them to the corresponding host. Port triggering is mainly

applied to online games, VoIPs and video players. Common applications include MSN

Gaming Zone, Dialpad and Quick Time 4 players, etc.

Follow the steps below to configure the port triggering rules:

Tips:

1. You can add multiple port triggering rules according to your network need.

2. If the application you need is not listed in the

Make Applications Free from Port Restriction by

DMZ

When a PC is set to be a DMZ (Demilitarized Zone) host in the local network, it is totally

exposed to the Internet, which can realize the unlimited bidirectional communication

between internal hosts and external hosts. The DMZ host becomes a virtual server with

all ports opened. When you are not clear about which ports to open in some special

applications, like IP camera and database software, you can set the PC to be a DMZ

host.

Note:

DMZ is more applicable in the situation that users are not clear about which ports to open. When it is enabled, the

DMZ host is totally exposed to the Internet, which may bring some potential safety hazard. If DMZ is not in use,

please disable it in time.

make the home PC join the Internet online game without port

restriction.

For example

,

due to some port restriction, when playing the

online games, you can log in but cannot join a team with other

players. To solve this problem, set your PC as a DMZ with all

ports opened.

Assign a static IP address to your PC, for example

192.168.1.100.

Make Xbox Online Games Run Smoothly by UPnP

UPnP (Universal Plug and Play) protocol allows the applications or host devices

to automatically find the front-end NAT device and send request to it to open the

corresponding ports. With UPnP enabled, the applications or host devices in the

both sides of NAT device can freely communicate with each other realizing the

seamless connection of the network. You may need to enable the UPnP if you want

to use applications for multiplayer gaming, peer-to-peer connections, real-time

communication (such as VoIP or telephone conference) or remote assistance, etc.

Tips:

1. UPnP is enabled by default in this modem router.

2. Only the application supporting UPnP protocol can use this feature.

3. UPnP feature needs the support of operating system (e.g. Windows Vista/ Windows 7/ Windows 8, etc. Some of

operating system need to install the UPnP components).

For example

, When you connect your Xbox to the modem router which has connected

to the Internet to play online games, UPnP will send request to the modem router to

open the corresponding ports allowing the following data penetrating the NAT to

transmit. Therefore, you can play Xbox online games without a hitch.
