🧭 1. Introduction: Why Upgrade the WireGuard Traffic Routing Solution?

In the early stages of setting up a self-hosted VPN, the common architecture usually consists of:

• WireGuard Server (Vultr)
• WireGuard Client (local device)
• Direct connection for domestic traffic / proxy for foreign traffic based on AllowedIPs

This solution seems simple and effective initially, but as usage time increases, several practical issues gradually emerge:

• Ports are easily blocked
• Traffic routing rules rely on IP ranges, making maintenance complex
• Clients require frequent synchronized configuration changes

❗ The Core of the Practical Issue

It is not that WireGuard is unusable, but rather:

❗ WireGuard’s design leans more toward a “point-to-point tunnel” rather than an “intelligent traffic routing system”

💡 Recommended Base Deployment Environment (Vultr)

For the underlying infrastructure of this solution, we recommend using:

👉 Vultr VPS as the base WireGuard node

Reasons:

• Deploying WireGuard is very simple
• Stable global node coverage
• Suitable as a standard VPN exit server

👉 Recommended configuration:

• Starting from 1 vCPU / 1GB RAM
• Ubuntu 22.04 / 24.04

👉 Official deployment link: Vultr

🧱 2. WireGuard Four-Stage Evolution Model (Summary of Real-World Practice)

The entire self-hosted WireGuard VPN system can be summarized into 4 stages:

🧱 Stage 1: WireGuard + AllowedIPs Routing (Basic Solution)

🔧 Architecture

WireGuard Server + WireGuard Client
AllowedIPs = 0.0.0.0/0 + GeoIP 排除

WireGuard Server + WireGuard Client
AllowedIPs = 0.0.0.0/0 + GeoIP 排除

⚠️ Practical Issues

The biggest problem at this stage is not configuration, but operational stability:

• VPS ports are frequently blocked
• After each block, you need to:

👉 Simultaneously modify:

• Server WireGuard port
• Client WireGuard port

📌 Key Reality

It is not a “one-time recovery”, but a cyclical process:

Change port → works for 2–5 days → blocked again → change again

❌ Core Flaws

• High maintenance costs on both ends
• Relies on IP rules (AllowedIPs)
• Not compatible with CDN / dynamic IP networks

🔧 Stage 2: iptables Multi-Port Forwarding (Server-Side Optimization)

🔧 Architecture Optimization

Introduce on the server side:

• iptables multi-port forwarding mechanism

✔ Improvements

Compared to Stage 1:

• ❌ No longer need to frequently change the WireGuard server port
• ✔ Multiple backup ports can be configured
• ✔ Quick switching to restore connection

⚠️ Key Change

When a port is blocked:

👉 Only need to modify the client port to restore the connection

📌 Essential Optimization

❌ Remaining Issues

• Clients still require manual port changes
• Routing still relies on IP rules
• Limited censorship resistance

🧠 Stage 3: WireGuard + Clash Verge Rev / FlClash (Modern Routing Solution)

🔧 Architecture

✔ Core Changes

• WireGuard: solely responsible for network connectivity
• Clash: responsible for intelligent traffic routing

✔ Advantages

• Supports DOMAIN / GEOSITE routing
• Automatic rule updates
• No longer relies on IP ranges
• Better adapted to CDN networks

⚠️ Current Issue (Real Situation)

If the server still uses the Stage 2 structure:

👉 After a port is blocked:

• Clients still require manual port changes

❌ Essential Issue of Stage 3

Clients still incur manual maintenance costs

🧠 Recommended Environment for Modern Routing Solution

This solution is applicable to:

• Vultr VPS
• Or other international cloud servers

👉 Recommended stable nodes for Clash routing:

• Vultr (Recommended)
• DigitalOcean (Alternative)

✔ Core Upgrades Compared to Stage 3

✔ Core Advantages

• 443 WebSocket tunnel
• Reduces the probability of port blocking
• Long-term stable operation
• Does not rely on frequent port changes

⚠️ Real Experience Notes

It should be noted that:

• Wstunnel configuration complexity is significantly higher than WireGuard
• Higher client configuration requirements (Clash / FlClash)
• High initial debugging costs

But in the long run:

✔ Stability is significantly better than a pure WireGuard architecture

🚀 Advanced Stability Solution (ZgoCloud)

For scenarios requiring higher stability, this solution has been migrated to:

👉 ZgoCloud VPS

Features:

• Multi-region data centers (Japan / US / Hong Kong, etc.)
• Superior network routes
• More suitable for long-term stable operation
