Analysis on virtual server settings of tengda Wireless Router

Tengda wireless router virtual server-port field ing

Start port ~ End port: the service port segment provided by the mapped Intranet host.

Intranet IP Address: the IP address of the computer that acts as the server in the LAN.

Protocol: Contains TCP, UDP, and all. If you are not sure about the protocols used, you can select all.

Enabled: only when this option is selected can the rules set for this entry take effect.

Delete: All the setting parameters of this item are cleared. In "common service port", common protocol ports are listed. You can select one of them and select a serial number in the ID, click "fill in" to automatically add the port to the list. You can also manually add ports not listed in common server ports.

For example, if you want to share some large files with friends outside your LAN, but the file is too large to transfer, you can build your computer into an FTP server, then, use the port field ing function of the tengda wireless router to allow your friends to access these files on your computer. Assume that the static IP address of the FTP server, that is, your computer, is 192.168.0.10, if you want your friends to access this server through the default port 21 and use the TCP protocol, follow these steps:

1 .. on the port field ing page, Enter ID Start port and ID end port 21. You can also select "FTP" in "common service port number ", enter port 21 in the corresponding setting box.

2. Enter 192.168.0.10 in the Intranet IP field, select TCP protocol, and select enable.

3. Illustration:

4. Click OK.

When your friends access this FTP server, simply enter ftp://xxx.xxx.xxx.xxx: 21 in your browser. Among them, xxx. xxx. xxx. xxx is the IP address of the WAN port of the tengda wireless router. If the IP address of the WAN port of your router is 172.16.102.89, enter ftp: // 172.16.102.89: 21 in the browser.

Note: If the configured port includes a virtual server with the Service port of 80, set the "remote WEB management" item in the "Security Settings" menu to a value other than 80, for example, 8080. Otherwise, a conflict occurs, resulting in unavailability of the virtual server.

Tengda wireless router virtual server-DMZ host

After the DMZ host is set in the LAN, the computer will be completely exposed to the WAN, which can achieve two-way unrestricted communication. Adding a client to DMZ may cause insecure local networks. Therefore, do not use this option easily .)

DMZ Host IP Address: Enter the IP address of the LAN computer on which you want to set the DMZ host.

Enable: Click to enable and disable the DMZ host.

For example, you can set a computer with the IP address 192.168.0.10 in the LAN as a DMZ host to implement bidirectional communication between the computer and another host on the Internet.

Note: When the host is set to a DMZ host, the computer is completely exposed to the Internet, and the firewall does not work for the host.

Tengda wireless router virtual server -- UPNP settings

UPnP (General plug-and-play network protocol). With the UPnP protocol, hosts in the LAN can request a router to perform specific port conversion, allows external hosts to access resources on internal hosts as needed.

Enable

DMZ Host IP Address: Enter the IP address of the LAN computer on which you want to set the DMZ host.

Enable: Click to enable and disable the DMZ host.

For example, you can set a computer with the IP address 192.168.0.10 in the LAN as a DMZ host to implement bidirectional communication between the computer and another host on the Internet.

Note: When the host is set to a DMZ host, the computer is completely exposed to the Internet, and the firewall does not work for the host.

Tengda wireless router virtual server -- UPNP settings

UPnP (General plug-and-play network protocol). With the UPnP protocol, hosts in the LAN can request a router to perform specific port conversion, allows external hosts to access resources on internal hosts as needed.

Enable UPnP: Click to enable and disable UPNP.

Note: This function takes effect only in Windows XP/Windows ME Operating System (Note: The system must be integrated or Directx 9.0 is installed) or in applications that support UPnP.

Virtual servers may be unfamiliar to common network users. If you do not know how to set them, it will be difficult to use this function. I hope this article will relieve you of some troubles.
