VigorACS 3 vs. VigorACS 2
VigorACS 2, DrayTek’s popular network management software, will be discontinued at the end of 2023.
It is replaced by VigorACS 3, which has all the features of VigorACS 2 but with improvements in the frontend and backend. These include the web interface and support for SD-WAN with:
- Auto VPN (Hub-and-Spoke as well as Full Mesh)
- Auto VoIP WAN
- Traffic Control with SD-WAN Route Policy
- Application Route Policy
An additional feature is Centralised Hotspot Portal.
Existing VigorACS 2 subscribers can upgrade to VigorACS 3 completely free of charge. The VigorACS 2 licence key is fully transferrable. For more information, check out the following Application Note: Click here >>

VigorACS 3 – Network Management Software
SD-WAN policy for HQ and branch

* Vigor3910 will be SD-WAN enabled in the latest firmware version 4.3.1
VigorACS 3 is the latest version of DrayTek’s popular network management software. It supports all current DrayTek routers, access points, and switches, providing an integrated platform for network administrators to configure, provision, and monitor DrayTek devices remotely from the comfort of their offices or homes.
VigorACS 3 is the core of the DrayTek SD-WAN solution, and provides a user-friendly interface with a responsive display that automatically adjusts and arranges content to suit a variety of devices such as PCs, tablets, or phones.
Compatible Devices for VigorACS 3
Why SD-WAN
- VigorACS 3 monitors Internet-based applications (VoIP, video conferencing, media streaming, web browsing, etc.), and displays usage and performance data (latency, loss, jitter, Mean Opinion Score (MOS) given by the users, call history, etc.).
- Network administrators can refer to these data, and set SD-WAN policies to ensure traffic for the selected applications (e.g. VoIP) to be routed through the best quality interfaces.

Network diagram with SaaS and Cloud applications for branches

An example of SaaS and Cloud applications from HQ with VigorACS 3
- User experience will be optimized with the SD-WAN policies, in addition to Load Balance, Failover, and Route Policy functions.
- The SD-WAN policies can be applied to routers at the headquarter or branches (i.e. edge routers), ensuring efficient use of router capacities under the network conditions.
- VigorACS 3 complements the MPLS protocol for HQ-branch traffic, and provides flexibility for SaaS and cloud-based applications that are becoming more common in recent networks. In a way, it plays a role like an orchestrator (i.e., an arranger for a piece of music).
SD-WAN Orchestrator
Quality-Driven Dashboard
The latency, loss, and jitter of every WAN/VPN interface is measured for quality and given a Mean Opinion Score (MOS). The quality-driven dashboard helps Network Administrators see the past and present reliability of interfaces at a glance.
VoIP MOS and SLA
VoIP data packets are monitored for call quality (latency, loss, and jitter) and every call is recorded in a call history list. Network Administrators can then easily retrieve information to check call quality.


VoIP Experience Optimisation
Based on the interface quality records, VigorACS 3 can adjust the metric to make sure all edge routers always use the best-quality interface for VoIP in order to optimise the VoIP experience.
Application Visibility and SD-WAN Policy
The application visibility feature lets Network Administrators understand data usage. From which client, via which WAN, to which application, at what time.
Based on the application visibility, Network Administrators can create SD-WAN policies to send business-critical applications through the best-quality interface in order to optimise the user experience.

Benefits of VigorACS 3
Time and Cost Saving Examples for VigorACS 3
There are many benefits that VigorACS 3 can offer, including saving time when setting up VPNs, and in firmware upgrades. Below are two tables outlining time and cost savings for these in a medium network with 20 nodes, and a large network with 500 nodes.
Setting up VPNs
| Network Size | 20 nodes | 500 nodes | ||

| Cost Saving (assuming IT Admin’s rate is $150/hr) | $488 | $12,188 | ||
Client Management with Captive Portal
VigorACS 3 as Captive Portal Server
Many of the Vigor Router and VigorAP models support captive portal functions, which can be used to redirect LAN clients to VigorACS 3 to go through the hotspot login process. This function is ideal for retail, restaurants, coffee shops, and hospitality to do WiFi marketing and learn more about their clients for future marketing campaigns.


Robust Multilingual Splash Page
Intuitively customise the splash page to meet business needs. Live preview provides a “what you see is what you get” experience of splash page editing. Supporting 20 different languages, restaurant/hospitality business owners can speak their customers’ language.
Terms and conditions, and marketing terms are also available, with the option that users must click on the checkboxes to get Internet access. Bandwidth limit, time quota, and device management can also be applied to client devices.
Hotspot Client Analytics
Besides the splash page, VigorACS 3 also provides a detailed analytics view, where business owners can gain an in-depth understanding of new customers, return customers, visiting frequency and which branches have been visited…etc. Further marketing campaigns can then be made accordingly.

Estimating VigorACS Storage Requirement
The storage requirement can be calculated by considering the number of nodes and the features in use.
- Influx DB data for device info (required): 20 MB per node
- Syslog (optional): about 48 MB per node, per day
- CFG backup for Vigor2962 or Vigor3910 (optional): about 250 KB per node
- CFG backup for DrayOS Routers (optional): about 25 KB per node.
For example, managing 500 DrayOS Routers with Syslog and CFG Backup daily for 1 month, the
required storage size will be:
- Influx DB data: 20 MB x 500 nodes= 10 GB
- Syslog: 48 MB x 30 days x 500 nodes = 720 GB
- CFG Backup: 25 KB x 30 days x 500 nodes = 375 MB
→ Total storage required: 10 + 720 + 0.375 = 730.375 GB

- Influx DB data for device info (required): 20 MB per node

- CFG backup for Vigor2962 or Vigor3910 (optional): about 250 KB per node
- CFG backup for DrayOS Routers (optional): about 25 KB per node.
For example, managing 500 DrayOS Routers with Syslog and CFG Backup daily for 1 month, the
required storage size will be:
- Influx DB data: 20 MB x 500 nodes= 10 GB
- Syslog: 48 MB x 30 days x 500 nodes = 720 GB
- CFG Backup: 25 KB x 30 days x 500 nodes = 375 MB
→ Total storage required: 10 + 720 + 0.375 = 730.375 GB

SD-WAN Orchestrator
Quality-Driven Dashboard
The quality of every WAN/VPN interface is measured by latency, loss, and jitter. The quality-driven dashboard helps Network Administrators check the reliability of interfaces at a glance.
VoIP MOS and SLA
Every VoIP call is also monitored by MOS, latency, loss, and jitter. With a call history list, Network Administrators can easily retrieve information for calls with poor quality.


VoIP Experience Optimisation
Based on the interface quality records, VigorACS 3 can adjust the metric to make sure all edge routers always use the best-quality interface for VoIP in order to optimise the VoIP experience.
Application Visibility and SD-WAN Policy
The application visibility feature lets Network Administrators understand data usage. From which client, via which WAN, to which application, at what time.
Based on the application visibility, Network Administrators can create SD-WAN policies to send business-critical applications through the best-quality interface in order to optimise the user experience.

Client Management with Captive Portal
VigorACS 3 as Captive Portal Server
Many of the Vigor Router and VigorAP models support captive portal functions, which can be used to redirect LAN clients to VigorACS 3 to go through the hotspot login process. This function is ideal for retail, restaurants, coffee shops, and hospitality to do WiFi marketing and learn more about their clients for future marketing campaigns.


Robust Multilingual Splash Page
Intuitively customise the splash page to meet business needs. Live preview provides a “what you see is what you get” experience of splash page editing. Supporting 20 different languages, restaurant/hospitality business owners can speak their customers’ language.
Terms and conditions, and marketing terms are also available, with the option that users must click on the checkboxes to get Internet access. Bandwidth limit, time quota, and device management can also be applied to client devices.
Hotspot Client Analytics
Besides the splash page, VigorACS 3 also provides a detailed analytics view, where business owners can gain an in-depth understanding of new customers, return customers, visiting frequency and which branches have been visited…etc. Further marketing campaigns can then be made accordingly.
