Henan router Vpn function setting detailed graphics and text tutorial? Before introducing how to use the router's Vpn function, let's first understand what Vpn is. Virtual private network is called virtual private network in English and virtual private network in Chinese. As the name implies, a virtual private network is a private network built on the mutual [US virtual machine leasing] network. It can establish a special communication line between two or more internal networks connected to the Internet in different places through a special encryption communication protocol. This private network only exists logically, and there is no actual physical circuit. Vpn is a remote access technology, which is simply to establish a private network on the public network for encrypted communication. Ordinary home users are not familiar with Vpn, so here is an example to illustrate how to use this function.

Take the wins7 system as an example to illustrate the steps:

1. Enter the "Network and Sharing Center" - click "Create a new connection or network" - select "Connect to the work area" - [Taiwan Expressway Server] - select "Use my Internet connection (Vpn)".

2. Enter the IP address of the server virtual private network in "Internet address", and then click "Next". Because the IP address of the router wAn port often changes, the DDN (Dynamic Domain NAME) function can map the dynamically changed IP address of the router wAn port to a fixed domain name. If ddns is enabled on the router, we only need to fill in the domain name in the "Internet address" position.

3. Next, after setting the user name and password of the virtual private network server (such as administrator) in the router, click Create.

4.4 Post. The Vpn connection is successful. Enter "FTP://Server IP Address: Service Number Port" in the browser or "My Computer" to access home computer data, for example: ftp://192.168.0.104:21 。

How often are Hong Kong, advanced defense and servers backed up? Whether website data is stored in a virtual machine or a physical server is always important in data backup. No matter how perfect the server is, there will inevitably be sudden problems such as hardware failure, network interruption, hacker attacks, etc. Therefore, in order to prevent data damage caused by sudden events, it is safer to backup data in advance. In order to make data backup. Users can backup general types of data in the following four ways :

1. File backup: transfer files and folders to another device

2. Version level or version control backup: supports file level and block level backup to copy information on the device, which is conducive to timely recovery in case of errors.

3. Server level backup: create the image of the client server to recover data in the event of a catastrophic failure.

4. Block level backup: faster than normal file backup. Block level backup can copy every piece of information on the device for recovery in case of serious errors.

Under normal circumstances, Hong Kong servers combine traditional version control with server level backup by using file or block level backup. This backup can be done regularly. Whenever the storage files on the host [benefits of virtual machine] change significantly, it is better to back up them once or several times a day. If it is a version backup, the best way is to create one during the update. In this way, when the software has problems, you can go back and rebuild it. Therefore, no matter what kind of server you are running, for different data file backup requirements, adopting appropriate methods can effectively improve the integrity of data backup, and the backup frequency depends on business requirements and functional requirements.
