Chapter 11 NAT Forwarding

Modem router’s NAT (Network Address Translation) feature makes the devices in the LAN use the same public IP address to communicate in the internet, which protects the local network by hiding IP addresses of the devices. However, it also brings about the problem that external host cannot initiatively communicate with the specified device in the local network.

The modem router can use a forwarding feature to lớn remove the isolation of NAT và allow external mạng internet hosts to lớn intuitively communicate with the devices in the local network, thus enabling some special features.

pokeht.vn modem router includes four forwarding rules. If two or more rules are set, the priority of implementation from high khổng lồ low is Virtual Servers, Port Triggering, UPNP & DMZ.

This chapter contains the following sections:

•Translate Address and Port by ALG

•Share Local Resources over the mạng internet by Virtual Server

•Open Ports Dynamically by Port Triggering

•Make Applications không tính phí from Port Restriction by DMZ

•Make Xbox Online Games Run Smoothly by UPnP


1. Translate Address và Port by ALG

ALG (Application Layer Gateway) allows customized NAT (Network Address Translation) traversal filters to lớn be plugged into the gateway to tư vấn address and port translation for certain application layer “control/data” protocols: FTP, TFTP, H323 etc. Enabling ALG is recommended.

Visit http://tplinkmodem.net, và log in with the trương mục you mix for the router. Go to lớn Advanced > NAT Forwarding > ALG.

*

•PPTP Pass-through: If enabled, it allows Point-to-Point sessions to be tunneled through an IP network and passed through the router.

•L2TP Pass-through: If enabled, it allows Layer 2 Point-to-Point sessions lớn be tunneled through an IP network and passed through the router.

•IPSec Pass-through: If enabled, it allows IPSec (Internet Protocol Security) lớn be tunneled through an IP network and passed through the router. IPSec uses cryptographic security services to lớn ensure private and secure communications over IP networks.

•FTP ALG: If enabled, it allows FTP (File Transfer Protocol) clients và servers khổng lồ transfer data via NAT.

•TFTP ALG: If enabled, it allows TFTP (Trivial tệp tin Transfer Protocol) clients và servers to lớn transfer data via NAT.

•H323 ALG: If enabled, it allows Microsoft NetMeeting clients to lớn communicate via NAT.

•SIP ALG: If enabled, it allows clients communicate with SIP (Session Initiation Protocol) servers via NAT.

•RTSP ALG: If enabled, it allows RTSP (Real-Time Stream Protocol) clients & servers lớn transfer data via NAT.

2. Nói qua Local Resources over the mạng internet by Virtual Server

When you build up a vps in the local network and want to tóm tắt it on the internet, Virtual server can realize the service and provide it to lớn the mạng internet users. At the same time virtual server can keep the local network safe as other services are still invisible from the internet.

Virtual hệ thống can be used for setting up public services in your local network, such as HTTP, FTP, DNS, POP3/SMTP & Telnet. Different service uses different service port. Port 80 is used in HTTP service, port 21 in FTP service, port 25 in SMTP service và port 110 in POP3 service. Please verify the service port number before the configuration.

I want to:

Share my personal website I’ve built in a local network with my friends through the internet.

For example, the personal website has been built on my home PC (192.168.1.100). I hope that my friends can visit my website. The PC is connected khổng lồ the modem router with the WAN IP address 218.18.232.154.

*

How can I do that?

1.Assign a static IP address khổng lồ your PC, for example 192.168.1.100.

2.Visit http://tplinkmodem.net, & log in with the tài khoản you phối for the router.

3.Go lớn Advanced > NAT Forwarding > Virtual Servers, click Add.

*

4.Click Scan, & choose HTTP. The external port, internal port and protocol will be automatically filled with contents. Enter the PC’s IP address 192.168.1.100 in the Internal IP field.

5.Click Save to save the settings.

*
Tips:

1.It is recommended khổng lồ keep the default settings of Internal Port và Protocol if you are not clear about which port & protocol khổng lồ use.

2.If the service you want to use is not in the Service Type, you can enter the corresponding parameters manually. You should verify the port number that the service needs.

3.You can showroom multiple virtual hệ thống rules if you want khổng lồ provide several services from a modem router. Please note that the External Port cannot be overlapped.

Done!

Internet users can enter http://WAN IP (in this example: http://218.18.232.154) khổng lồ visit your personal website.

Tips:

1.For a WAN IP that is assigned dynamically by ISP, it is recommended lớn apply and register a tên miền name for the WAN by DDNS, go lớn Set Up a Dynamic DNS Service account for more information. Then you can use http://domain name to visit the website.

2.If you have changed the mặc định External Port, you should use http://WAN IP: External Port or http://domain name: External Port lớn visit the website.

3. Xuất hiện 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 lớn 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 returns to lớn the external ports, the modem router can forward them to lớn the corresponding host. Port triggering is mainly applied lớn online games, VoIPs and clip players. Common applications include MSN Gaming Zone, Dialpad, Quick Time 4 players, và so on.

Follow the steps below to lớn configure the port triggering rules:

1.Visit http://tplinkmodem.net, và log in with the tài khoản you phối for the router.

2.Go to lớn Advanced > NAT Forwarding > Port Triggering & click Add.

*

3.Click Scan, and select the desired application. The triggering port và protocol, the external port và protocol will be automatically filled with contents. Here we take MSN Gaming Zone as an example.

4.Click Save to lớn save the settings.

*
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 Existing Applications list, please enter the parameters manually. You should verify the external ports the application uses first and enter them into External Port field according khổng lồ the format the page displays.

4. Make Applications không tính tiền from Port Restriction by DMZ

When a PC is set khổng lồ be a DMZ (Demilitarized Zone) host in the local network, it is totally exposed lớn the internet, which can realize the unlimited bidirectional communication between internal hosts and external hosts. The DMZ host becomes a virtual vps with all ports opened. When you are not clear about which ports to open in some special applications, lượt thích IP camera & database software, you can set the PC khổng lồ be a DMZ host.

*
Note:

DMZ is most applicable when you don’t know 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.

I want to:

Make the trang chủ PC join the mạng internet online game without port restriction.

For example, Due to some port restriction, when playing the online games, you can login normally but cannot join a team with other players. Lớn solve this problem, set your PC as a DMZ with all ports opened.

How can I do that?

1.Assign a static IP address khổng lồ your PC, for example 192.168.1.100.

2.Visit http://tplinkmodem.net, và log in with the account you set for the router.

3.Go to Advanced > NAT Forwarding > DMZ and select the checkbox lớn enable DMZ.

*

4.Enter the IP address 192.168.1.100 in the DMZ Host IP Address filed.

5.Click Save lớn save the settings.

Done!

The configuration is completed. You’ve phối your PC lớn a DMZ host and now you can make a team to game with other players.

5. Make Xbox Online Games Run Smoothly by UPnP

UPnP (Universal Plug và Play) protocol allows the applications or host devices khổng lồ automatically find the front-end NAT device & send request to lớn it to xuất hiện 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 khổng lồ use applications such as multiplayer gaming, peer-to-peer connections, real-time communication (for example, VoIP or telephone conference), or remote assistance.

*
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 tư vấn of operating system (e.g. Windows Vista/ Windows 7/ Windows 8, etc. Some of operating system need to lớn install the UPnP components).

For example, when you connect your Xbox to lớn the modem router which has connected to the internet to play online games, UPnP will send request to lớn the modem router to mở cửa the corresponding ports allowing the following data penetrating the NAT lớn transmit. Therefore, you can play Xbox online games without a hitch.

*

If necessary, you can follow the steps lớn change the status of UPnP.

1.Visit http://tplinkmodem.net, and log in with the tài khoản you phối for the modem router;

2.Go to lớn Advanced > NAT Forwarding > UPnP & toggle on or off according khổng lồ your needs.
