Router DMZ host several FTP setup simple diagram

First, determine the following network parameters of the server (to be used later)
[Native address], [gateway address], [subnet mask], [bedroom IP address]

1, open the Start menu, select Run, input cmd and enter;
2, in the Open Command Line window input Ipconfig/all and enter, you can see similar to the following figure results:


3. Write down [native address], gateway address, and subnet mask as shown above.
The above three parameters on your machine may be different from the above picture, but the general [native address] is similar
192.168.X.Y, [gateway address] is similar to 192.168.x.1, [subnet mask] is generally
255.255.255.0
4, in order to set up the DMZ host, we can not use the DHCP function of the router, you need to manually specify [native address].

In the network Connection entry in Control Panel, right-click on the local connection to select Properties, and you can get the following figure:

Select Internet Protocol (TCP/IP) and click Properties to get the following dialog box:

Fill in the parameters as shown above, where the IP address fills in the 192.168.x.y, the subnet mask fills in 3 of the [subnet]
Mask], the default gateway fills in the [gateway address] obtained in 3, and the others are filled in as shown.
5, as for [bedroom IP address], you can send a post on the BBS, and then look at the post at the bottom of the IP address displayed

Is your bedroom's [bedroom IP address] ^_^

Second, set up the DMZ host
The following settings take the Tp-link R402 router as an example, the other routers are set up much the same as the DMZ
1
Say different, such as Tenda is the permeability Area menu item. 1, open the browser, enter [gateway address] and return,
1, open the browser, enter [gateway address] and return, you will see the following figure:

2. Enter the username and password on the map (note the case), enter the router Setup interface as follows:

3, according to the picture on the left menu to find the DMZ host, fill in parameters and click to save;

Third, FTP server-side settings
The following only takes Serv-u as an example, because it is easier to get (comic), and two is because it compares

Simple, most beginners use this.
Only the settings related to the DMZ are explained here, and other settings refer to other tutorials in the essence area.

1, as shown in the following figure, select a field below the left field menu, fill in the relevant parameters on the right and save;

The FTP port address recommends that you fill out a 21-and-larger port number, such as 2121, 8021, and so on.

2, as shown in the following figure, select settings below the field and select Advanced page on the right, fill in the relevant parameters and save

At this point, your FTP should be accessible to everyone, the address format is as follows:

ftp://user:password@[bedroom IP address]:[ftp port]

(User and password are the username and password of the account that you set up in Serv-u, [bedroom IP address] in one, 5
, [FTP port] is the port number set in three, 1)

For example, a router is similar to a telephone switch in a unit.
Each extension can be called, but if someone wants to call in, only know the switchboard number is not, do not know the extension can not be transferred to a specific part of the machine. Usually we hear the hint is "please dial the extension number, please dial 0", do not know the other extension number, we have to dial 0, dial 0 to go to a specific extension, this part of the router is equivalent to the DMZ host.
The common home Internet router is the equivalent of a less functional telephone switch. By default, only dial out is supported, that is, browsing the web, e-mailing, and so on. But if you want to build a Web page, let other people to visit, or provide other services for the extranet, or want to be through NetMeeting by other people outside the network can not be called, because the access information to the router after the block blocked, the external network of computers can not contact the intranet computer. The default state is only one-way communication.
The easiest way to do this is to enable the DMZ host. All information sent to the router's external network address is forwarded to the specified DMZ host by the router.
Of course, a better approach is to set the forwarding rules as needed.
