After purchasing QNAP NAS, many users are not familiar with how to remotely access QNAP NAS in an external public network environment, but this is very necessary. Therefore, this tutorial shares how to realize remote access to the QNAP NAS connected to the home intranet, without the need for a public network IP, and without setting up a router, simply through [cpolar intranet penetration] (cpolar - a safe intranet penetration tool ) to fulfill.
1. QNAP installs cpolar intranet penetration
Note: QNAP needs to be an X64 CPU, we can achieve it by installing the docker version
Enter App Centrer, download the container toolcontainer station
Enter Container Station, then select Create, then search cpolar, find the cpolar image, and click Install
Configure the network during installation, click to open advanced settings
Change the network mode to host, then click create
After creation, you can see the cpolar container in the list
Open the browser and access QNAP ip+:9200, you can access the cpolar web UI management interface, and log in with the cpolar email account
2. Intranet penetration
2.1 Create a tunnel
After cpolar is successfully installed, we can create a tunnel to map the internal network port, and we will get the corresponding public network address, so that we can log in remotely to access the QNAP management interface outside.
The QNAP management interface port is 8080 by default, so let’s create a http protocol tunnel and map the QNAP port 8080. Click Tunnel Management on the left dashboard - Create Tunnel:
- Tunnel name: can be customized, be careful not to duplicate the existing tunnel name
- protocol: http
- Local address: 8080
- Domain name type: choose a random domain name for free
- Region: Selected by default
click创建
After the tunnel is successfully created, click on the status on the left - online tunnel list, you can see that the tunnel just created has generated a corresponding public network address, copy it
2.2 Test public network remote access
Copy the public network address and open the browser to access, and the login interface appears to indicate success
3. Configure a fixed second-level subdomain name
Since the address created above is a random address, the address will change within 24 hours. For a better user experience, you can fix the http public network address and configure a fixed second-level subdomain name for it. The address will not change randomly, and the bandwidth will be improved at the same time.
It should be noted that to configure a fixed second-level subdomain name, you need to upgrade cpolar to the basic package or above.
3.1 Reserved second-level subdomains
Open the official website of cpolar ( www.cpolar.com ), log in to the background, click Reserve on the left, and find the reserved second-level subdomain name. Let’s reserve a second-level subdomain name for remote access to QNAP NAS
- Region: Select China
- Second-level domain name: customizable
- Description: Remarks, which can be customized
click保留
After the cpolar second-level subdomain is reserved, we will copy it down
3.2 Configure the second-level subdomain name
Go back to the web ui management interface of QNAP cpolar, click the tunnel management on the left dashboard - tunnel list, find the remote tunnel we just created, click edit on the right
Modify the tunnel information, and configure the successfully reserved second-level subdomain name into the tunnel
- Domain name type: select a second-level subdomain name
- Sub Domain: Fill in the reserved second-level sub-domain name, in this example
wlt
click更新
After the tunnel update is successful, then check the online tunnel list. At this time, you can see that the public network address has changed to the second-level subdomain address we set, and then copy the address
4. Use fixed sub-domain name for remote access
Access the fixed second-level subdomain name on the browser, and the login interface will appear to indicate success, and then we can remotely manage our QNAP service, and now the public network address will not change randomly.
