Turn on the VPN service on the router, wherever we can access the resources in the home network, and easily and securely access the data in the home network. Below, the system home will introduce how to open the router VPN service. Using the router's DMZ (Quarantine) settings or applications that use network storage, we are able to access resources on the home network over the Internet. But to ensure that communication data is not intercepted, we should use VPN (Virtual Private Network) whenever possible. Through the VPN service, we can easily and securely access the home network and handle all kinds of sensitive data. If other people want to try to intercept our network communication data, then they will only get encrypted VPN communication data, and can't really steal our data. To enable the VPN service on the router, the prerequisite is that the router needs to support this function. Secondly, if the home network accesses the Internet to obtain a dynamic Internet IP address, the router must also support the dynamic domain name (DDNS) function. Currently, most routers can support these two functions, but some routers may need to update the firmware before they can be supported. Take the ASUS RT-N16 wireless network router as an example. On the Web Settings page, click on the left side of the system management, click on the right side of the "Firmware Update" tab, click "Check" & rdquo; The button finds the new firmware. After confirming the update after finding the new firmware, the router will automatically download and update the firmware. Since most home networks use ADSL access methods with limited upload bandwidth, downloading data from the home network will be slower. When we access the home network through VPN, we must be psychologically prepared for this, and we can do some related preparations in advance. For example, when saving photos on the home network storage, the photos are properly classified and thumbnails are prepared so that we can quickly find the photos we need when accessing via VPN. In any case, accessing resources on the home network via the Internet makes VPN the easiest and safest way. Therefore, no matter whether we need it or not, we should also master the method of opening VPN service for the router. Below, we will use the ASUS RT-N16 wireless network router as an example to demonstrate the specific method of opening and using VPN services. Is there a problem with the VPN?

Note that in addition to considering the security of the password when setting the password, it must also be considered that the high-intensity password is difficult to input on the mobile device. 3 Detailed Settings Click to switch to the “VPN Details” tab to set the IP address that the VPN server can use to assign to the remote login user. Usually the router will automatically give the network segment that can be used. Finally, select the authentication method and encryption strength of the server as needed, and click the “Apply this page setup” button to save the settings. Remember to remember the authentication method and encryption method you choose to make the appropriate settings on the client. 4 Dynamic Domain Name If you get a dynamic IP address, then you need to go to “External Network
