How AnyLink Provides a Lightweight, Secure SSL VPN for Remote Work

Company wants to support remote work but does not want to buy commercial SSL VPN equipment or deal with complex OpenVPN; looking for a lightweight, secure, user‑manageable solution.

I recommended the open‑source project I have used in production for two years: https://gitee.com/bjdgyc/anylink

1. What is AnyLink? — A lightweight SSL VPN server

AnyLink is an open‑source SSL VPN server written in Go, supporting:

Standard SSL/TLS encrypted tunnels (based on TUN virtual network interface)

Multi‑user account management (Web UI for creating/disabling users)

Seamless internal resource access (Web, SSH, SMB, databases, etc.)

Cross‑platform clients (Windows / macOS / Linux)

Private deployment with full data control

Key positioning

AnyLink is not a port‑mapping tool like frp or ngrok; it gives remote devices an internal IP so they can access all intranet services as if they were on the corporate LAN.

2. Why choose AnyLink?

Reasonable advantages

Simple deployment Single binary or one‑line Docker command, no complex dependencies.

User‑friendly management Built‑in Web console to create accounts, set expiration, view online status, suitable for small‑to‑medium teams.

Lightweight client Windows client around 10 MB, automatically configures routes after connection, no manual host or port changes.

Pure internal access, no middle proxy All traffic is TLS‑encrypted directly to the server, meeting enterprise security requirements.

Fully open source, Gitee hosted Transparent code, fast domestic download, suitable for data‑compliance‑sensitive teams.

3. Typical use cases

Operations staff SSH into internal servers from home. Developers remote access GitLab/Jenkins/Databases. Finance staff securely connect to ERP systems. Branch offices connect to headquarters intranet, replacing traditional hardware VPN. Note: AnyLink is not for “scientific internet” or bypassing network restrictions; it is an enterprise‑grade internal network access tool.

4. Quick start (Docker deployment)

# Start server listening on port 4430
version: "3.8"
services:
  anylink:
    container_name: anylink
    restart: always
    privileged: true
    environment:
      - IPTABLES_LEGACY=on
    ports:
      - "443:443"
      - "8800:8800"
      - "443:443/udp"
    volumes:
      - /sj-data/web/vpn/conf:/app/conf
    image: bjdgyc/anylink:latest
    command: ["-c=/app/conf/server.toml"]

Additional commands to pull the image, generate passwords, JWT secret, and view configuration options are provided.

After starting, visit http://your-server-IP:8080 to initialize the admin account, then create user accounts in the Web UI and download the appropriate client.

5. Final thoughts

Securely “open the intranet” is a capability.
In the era of remote work, “can we safely access the intranet” has become a basic skill for developers and operations.

Try an open‑source tool like AnyLink to regain control, keep data out of third parties, enjoy fully autonomous configuration, and incur almost zero cost.
