The "traditional office" is no longer the sole hub for productivity. Remote work has firmly established itself as a strategic necessity, driving business continuity and operational flexibility. However, this shift introduces complex security challenges. How can employees securely access internal servers, shared files, and sensitive corporate applications from home or while traveling without exposing the organization to data breaches and cyber espionage?
This is where Virtual Private Network (VPN) technology becomes your indispensable first line of defense, creating an encrypted tunnel that protects vital data from its point of origin to the corporate network. Globally recognized as a pioneer in networking solutions, DrayTek delivers an integrated ecosystem that bridges robust hardware with user-friendly software through the Smart VPN Client, providing users with a seamless, secure, and highly stable connection to DrayTek Vigor routers.

Business Value: Operational Use Cases
Deploying this architecture within your organization does more than just secure a connection; it enables your remote workforce to operate exactly as if they were physically present at headquarters. It grants secure access to:
-
Internal Servers: Manage databases and proprietary applications securely without exposing them to the public internet.
-
Shared Files: Seamlessly exchange large documents and assets across Network-Attached Storage (NAS) or local file servers.
-
Corporate Systems (ERP/CRM): Monitor production lines, track sales pipelines, and manage HR operations in real-time from anywhere in the world.
Prerequisites: Downloading and Initial Preparation
To guarantee a smooth setup process free of technical hurdles, please complete the following preliminary steps:
-
Download the Software: Always ensure you download the official and latest version to benefit from the most recent security patches. You can download the client directly from the official DrayTek portal here:
-
Router Readiness: Verify that your Vigor router has a stable internet connection and is configured with a reachable Public WAN IP so external client devices can locate and connect to it.
-
Handling Dynamic IPs: If your corporate internet plan lacks a Static IP, you should enable the DDNS (Dynamic DNS) service on the router. This assigns a permanent domain name (e.g., company.draytek.me) that automatically tracks your changing public IP, allowing remote users to connect via the domain name rather than changing numeric IPs.
Part 1: Configuring the DrayTek Vigor Router (Server-Side)
Securing your remote gateway begins inside the router management console to prepare it for handling incoming connection requests. Follow these steps precisely:
Step 1: Enable Remote Access Permissions
-
Log into your DrayTek Vigor router’s web management interface via your browser.
-
Locate the SSL VPN Service option and check the box to enable it. This protocol is highly recommended for its perfect balance of simplicity and strong encryption over its designated port.
Step 2: Create Employee Accounts (User Profiles)
To maintain strict access control and auditing trails, a distinct profile must be generated for each remote user:
-
From the sidebar, navigate to: VPN and Remote Access $\rightarrow$ Remote Dial-In User.
-
Click Add to create a new user profile.
-
Define Connection Type: Under the Allowed Dial-In Type section, check the box exclusively for SSL Tunnel.
-
User Credentials: Enter a secure Username and Password for the designated employee.
Note: You cannot use "admin" as a username for a VPN account. This username is strictly reserved for core router administration via HTTPS. Using it for VPN connections presents a security vulnerability and is automatically rejected by DrayTek systems.
Part 2: Configuring the Smart VPN Client on Windows
With the router prepared, we now move to the employee's machine (using Windows as our reference platform) to configure the client software:
-
Launch the Client: Open the Smart VPN Client application you installed earlier.
-
Add a New Connection: From the main dashboard, click the Add button to initiate a new VPN Profile.
-
Input Connection Details: Complete the configuration window using the following parameters:
-
Profile Name: Assign a recognizable identifier for the network (e.g., Company_HQ_VPN).
-
Type: Select SSL VPN Tunnel from the protocol dropdown menu.
-
IP or Hostname: Input your company's static WAN IP address or the configured DDNS hostname.
-
Username & Password: Enter the exact credentials created for this user on the router in Part 1.
-
Fast SSL: Check the box to enable Fast SSL. This optimizes data throughput and reduces network latency without compromising encryption standards.
-
Click OK to save the profile.
Part 3: Initiating and Managing the Connection
Your secure digital pathway is now fully configured and ready for launch:
-
Trigger the Connection: On the main application interface, select the VPN profile you just created and click the Connect button.
-
Identity Verification: A prompt will appear asking to confirm your credentials. Verify that your username and password are correct, then click OK.
-
Authentication Phase: The client will establish an encrypted handshake with the Vigor router, validating credentials and securing the digital tunnel.
-
Successful Connection: Once established, the connection status within the application will shift to a green "Connected" state.
You are now securely linked to your company’s internal network. You can access shared network drives, interact with local servers, and execute your daily workflows remotely with the exact same capabilities as an on-site employee all while staying completely shielded from external cyber threats.
