OpenVPN to Vigor Router by using the self-generated certificate

Vigor Router support generating certificates for OpenVPN since firmware version 3.9.4. This article demonstrates how to create OpenVPN from different clients to Vigor Router with the self-generated certificates.

1. Create a remote dial-in user profile: Go to VPN and Remote Access>> Remote Dial-in User, click on an available index to edit the profile.

2. Edit the profile as follows:

Check Enable

For Allowed Dial-In Type, check OpenVPN Tunnel

Give it a username and a password

Click OK to save

3. Go to VPN and Remote Access >> Remote Access Control and ensure OpenVPN Service is enabled.

4. Confirm the time is correct on the router via System Maintenance >> Time and Date page.

5. Go to VPN and Remote Access >> OpenVPN >> OpenVPN Server Setup,

• Enable TCP Mode or UDP Mode, depends on which transfer protocol you would like to use for OpenVPN connections
• Customize the TCP Port and UDP Port if you want

6. Generate certificates

• Choose Router generated certificates
• Click GENERATE
• Click OK

7. Go to OpenVPN Client Configuration page:

Choose the WAN that allows OpenVPN connection for Interface

Select the Protocol you would like to use

Give a Config filename

Click Export to save the VPN configuration file, and send it to the OpenVPN client devices, or Send it by Email

The value of UDP Ping means if no packets have been sent for at least n seconds, the router will ping remote over the TCP/UDP channel. It has two intended uses:

Compatibility with stateful firewalls. The periodic ping will ensure that a stateful firewall rule which allows OpenVPN UDP packets to pass will not time out.

 To provide a basis for the remote to test the existence of its peer.

The value of UDP Ping exit means after n seconds pass without reception of a ping or other packet from remote, OpenVPN will exit.

For example, when the UDP Ping exit is set to 60, OpenVPN will exit within 60 seconds if its peer disconnects.

8. Go to VPN and Remote Access >> SSL General Setup, and select openvpn server certificate as the server certificate.

You may use any OpenVPN Client App for the connection. All you need to do is import the configuration file exported from the router, and enter the username and password when being asked for credentials.
