How to Configure ASUS Merlin Routers for VPN: Complete Setup Guide

Set up VPN proxy access on ASUS Merlin firmware by installing the FancySS plugin, importing a V2Ray or SSR subscription link, and selecting the appropriate routing mode.

The fanqiang repository provides a curated collection of guides for bypassing internet restrictions across multiple platforms. For ASUS Merlin router users, the project offers a self-contained tutorial that enables VPN-like proxy functionality without external scripts or manual configuration files.

Where the ASUS Merlin Guide Lives

The router-specific documentation resides in the router/ directory. According to the bannedbook/fanqiang source code, the primary file is [router/Merlin.md](https://github.com/bannedbook/fanqiang/blob/master/router/Merlin.md), which contains a complete walkthrough for installing the "科学上网" (scientific-internet-access) plugin and configuring it with subscription-based proxies.

The repository also includes [router/readme.md](https://github.com/bannedbook/fanqiang/blob/master/router/readme.md) as an index page listing available router tutorials, and [README.md](https://github.com/bannedbook/fanqiang/blob/master/README.md) providing the high-level overview linking to all platform guides.

Step 1: Install the FancySS Plugin

The Merlin firmware does not include proxy functionality by default. You must install the FancySS package from the third-party FancySS project.

1. Visit https://github.com/hq450/fancyss and locate the release matching your router's architecture (e.g., fancyss_merlin_x64.tar.gz for x64 models).

2. Open your router's web interface, navigate to Software Center, click Install, and select the downloaded archive.

The plugin integrates directly into the ASUS Merlin administration panel. No SSH access or command-line configuration is required for basic operation.

Step 2: Add Your Subscription Link

Once installed, configure the plugin with a V2Ray or ShadowsocksR subscription:

1. Open 科学上网 → 订阅地址管理 (Subscription Management).

2. Paste your subscription URL. This typically comes from a V2Ray airport service or free node list:

   
   https://example.com/subscription/abc123.txt
   

3. Click 保存并订阅 (Save and Subscribe). The plugin automatically fetches and parses all available servers.

The guide includes UI screenshots hosted on v2free.org (e.g., meilin1.png, meilin2.png) that illustrate this workflow visually.

Step 3: Select Routing Mode and Enable

After importing servers, configure traffic handling:

Mode	Purpose
大陆白名单模式 (Mainland Whitelist)	Routes only international traffic through proxy; domestic sites connect directly.
游戏模式 (Gaming Mode)	Restricts proxy to gaming traffic only; minimizes latency for other applications.

To activate:

1. Navigate to 账号设置 → 插件开关 → 打开 (Account Settings → Plugin Switch → On).

2. Select your preferred 模式 (mode) from the dropdown.

3. Pick a server from the populated list and click 确定 (Confirm).

The plugin applies rules immediately without router reboot.

Compatibility and Related Resources

The router/ directory covers multiple firmware options. While this guide focuses on ASUS Merlin, the repository also provides [router/OpenWRT.md](https://github.com/bannedbook/fanqiang/blob/master/router/OpenWRT.md) for OpenWRT-based routers.

The main README.md links to companion guides for:

• Android: V2RayNG, ShadowsocksR
• iOS: Surge, QuantumultX
• macOS: V2rayX, ClashX
• Windows: V2RayN, ShadowsocksR

Summary

• Install the FancySS plugin from the FancySS project repository—choose the correct architecture for your router model.

• Import a V2Ray or SSR subscription URL through the 订阅地址管理 interface; the plugin auto-parses server configurations.

• Select either 大陆白名单模式 for general browsing or 游戏模式 for targeted gaming traffic.

• Reference the router/Merlin.md file in bannedbook/fanqiang for full visual guidance with embedded screenshots.

Frequently Asked Questions

What subscription services work with the ASUS Merlin FancySS plugin?

Any V2Ray or ShadowsocksR (SSR) subscription URL is compatible. The plugin parses standard base64-encoded subscription formats. Free node lists and paid V2Ray airport services both function; paste the subscription link into 订阅地址管理 and click 保存并订阅 to populate the server list.

Does this require enabling SSH or running commands on the router?

No. The FancySS plugin installs through the standard ASUS Merlin Software Center, and all configuration occurs through the web-based "科学上网" interface. SSH access is only necessary for advanced troubleshooting or manual rule editing, not for basic VPN setup.

What is the difference between 大陆白名单模式 and 游戏模式?

大陆白名单模式 (Mainland Whitelist) proxies all traffic except Chinese domestic websites, balancing speed and access. 游戏模式 (Gaming Mode) restricts proxy usage to gaming applications only, leaving all other traffic direct—ideal when you need minimal latency for non-gaming activities.

Where can I find the offline package for my specific router architecture?

Visit https://github.com/hq450/fancyss and match your router's processor type. Common variants include fancyss_merlin_x64.tar.gz for x64-based routers and ARM-specific builds for other models. The bannedbook/fanqiang router/Merlin.md guide links directly to this repository for the latest releases.
