1. Use Let's Encrypt Certificate for your DDNS Domain

Vigor Router support importing a Let's Encrypt certificate from its web user interface. It makes the process of generating, signing and importing the certificate very easy. This document will show how to apply a Let's Encrypt for the router's domain.

2. Schedule a Router Reboot

Vigor routers offers time schedule function, which Network Administrator can use it to reboot the router during non-business hours for example. This article shows an example of schedule a reboot every work day

3. Activate DrayDDNS Service for a Free Hostname

Since firmware version 3.8.7 on DrayOS models, and 1.4.0 on Linux models, a free DDNS service - DrayDDNS is provided to every Vigor Router. Each device can register for one hostname at the domain, and it works for all the WAN interfaces. This article will demonstrate how to set up the DrayDDNS service on your router.
(Note: Vigor2925 series support DrayDDNS since version, and Vigor2862 series support it since 3.8.5)

4. Renew License Key for WCF Service

This article demonstrates how to add a new license key for the router's WCF service.

5. Get Notified About Connection Loss by Email

Vigor Router can send the email to notify the network administrator for the events including

  • WAN disconnect / reconnect
  • VPN disconnect / reconnect
  • Temperature Alert, when the temperature detected by the attached thermometer out of the defined range
  • WAN budget, when reaching the WAN budget limit
  • Central VPN Management: CPE offline, CPE config backup / restore fail, CPE firmware upgrade fail, and CPE VPN profile setup fails
  • High Availability, when the WAN of primary router failed and the secondary router take over, configuration sync between primary and secondary router fail, and one of the routers becomes unstable

Note that the options available vary between models. This article shows how to configure the router to send Email notification for WAN and VPN disconnect/reconnect for example.

6. Use High Availability in Active-Standby Mode (For Vigor3900 and Vigor2960)

In the following paragraph, we will demonstrate how to set up the Active-Standby mode High Availability.

7. Use High Availability in Hot-Standby Mode

High Availability (HA) is a feature that allows the network administrator to another router to the network for hardware redundancy. In Hot-Standby Mode, The primary and secondary router share the same WAN source; however, usually, only the primary is online. When the primary router goes down, the secondary comes up, dial up the same WAN line, and continue to provide Internet service to LAN clients.

8. Access a Vigor130 in Bridge Mode

This article describes how to access the management page of a Vigor130 operates in bridge mode. When in bridge mode, a Vigor130 cannot be accessed directly since it acts as a modem; however, if the Internet service is using VLAN tag, we can create a un-tagged virtual WAN interface linked to the LAN of Vigor130 on the Vigor Router and access the management page of Vigor130 from the virtual WAN.

9. Upload Firmware to the Router via TFTP

Vigor Router supports Trivial File Transfer Protocol (TFTP), which provides a method to send firmware file to the router without logging into the router's management page. This article demonstrates how to turn the router into a TFTP server, and how to upload a file to the router by a Windows PC and a Mac.

10. Manage the Router from the Internet

Vigor Router offers remote management access; however, it is disabled for security reason. If you would like to manage the router from the Internet, follow the steps below.

11. Hot-Stanby Mode vs. Active-Standby Mode

High Availability (HA) is a simple solution for business downtime caused by hardware failure. When HA is enabled, the network administrator can have a second router on the network to deliver full routing services during the downtime of the main router. Virtual IP is used for LAN clients' gateway IP, so there is no configuration change required when the backup router takes place.

DrayTek High Availability (HA) feature offers two modes, Hot-Standby and Active-Standby, this article explains the difference between them.

12. Use Dynamic DNS (DDNS) for Router's Access

Dynamic DNS service is the solution when you want to access the router from the Internet, but it has a dynamic IP address. You can sign up for a Dynamic DNS service and register a hostname for the router. With Dynamic DNS setup, the router will update the server its current WAN IP address to the Dynamic DNS server periodically.

13. How to login my Vigor Router

This article shows how to access the router's web-based management interface when it's in the default configuration.

14. Use a Unique Self-Signed Certificate on the Router

Due to security concerns, it is strongly recommended to have a unique private key on each device for self-signed SSL. This article shows how to generate a unique self-signed certificate then replace the default one on Vigor Router.

15. Transfer the Router and License Key to Another MyVigor Account

Before handing over your Vigor router to a new owner, remember that if the router has been registered with your MyVigor account, you should also transfer the router to the new owner's MyVigor account. Please follow the instructions to transfer Vigor Router and its license to a new owner.

16. How do I limit IP to access the management interfaces of router

If there are multiple subnets on the router, Network Administrator may set up LAN-based or IP-based access control at system maintenance >> management to prevent un-authorized LAN clients from logging into the router and change the router's settings.

17. Use Bonjour on Vigor Router
