While accessing the router via HTTPS, the browser might say the certificate given by the router is invalid. To improve this, Network Administrator could apply for a certificate from the trusted third party agent then import it to Vigor Router and use it for HTTPS Access.
Vigor3900, Vigor2960, and Vigor300B support three types of certificate:
The following steps will show how to use import a certificate for an HTTPS connection, and in this example, we will use the type "Certificate and Private Key".
1. From the Online Status page, check if the Current System Time of the router is correct.
2. Open Certificate Management >> Local Certificate page, click Upload:
3. At Local Certificate page, the imported certificate will be displayed with Status "OK" if the upload is successful.
4. At System Maintenance >> Access Control, select the certificate we just imported for Server Certificate, then apply the settings.
5. Now, access the router's HTTPS management page, and we should see the certificate information is changed. (The default certificate will show the issuer is Vigor3900)
Before uploading a certificate to Vigor3900, it is better to check the certificate file and key file with Notepad++ first. If the file format is Windows format, please convert it to UNIX format with the steps below:
1. Open the certificate with Notepad++ and the file format will be shown in the lower right corner.
2. Select Edit >> EOL Conversion >> UNIX/OSX format.3. The file format will change to UNIX.
