🧭 1. Introduction: Why do you need to upgrade the WireGuard diversion plan?

In the early practice of self-built VPNs, the common architecture is usually:

• Wireguard Server (Vultr)
• Wireguard Client (local device)
• Realize domestic direct connection / foreign travel agent based on allowedips

This approach seems simple and effective at the beginning, but gradually exposes several real problems as the usage time grows:

• Ports are easily blocked
• The shunt rule depends on the IP segment and the maintenance is complicated
• The client needs to frequently synchronize and modify the configuration

❗ The essence of practical problems

Not WireGuard is not available, but:

❗ Wireguard’s design is more ‘point-to-point tunnel’ than ‘intelligent shunt system’

💡 Recommended Deployment Environment (VULTR)

In the infrastructure of this scheme, it is recommended to use:

👉 Vultr VPS as the WireGuard base node

Reason:

• Deploying WireGuard is very easy
• Global node coverage is stable
• Suitable as a standard VPN export server

👉 Recommended configuration:

• 1 vCPU / 1GB memory start
• Ubuntu 22.04 / 24.04

👉 Official deployment entrance:vultr

🧱 2. Wireguard four-stage evolution model (real practice summary)

The entire WireGuard self-built VPN system can be summarized in 4 stages:

🧱 Stage 1: Wireguard + AllowedIPs (basic scheme)

🔧 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 problem

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

• VPS ports are often blocked
• Each time you need to be blocked:

👉 Modify simultaneously:

• Server WireGuard port
• Client WireGuard port

📌 Key reality

Instead of ‘recovery once’, it’s a looping process:

Replacement port → available for 2-5 days → blocked again → replace again

❌ Core flaws

• High cost of maintenance
• Depends on IP rules (allowedips)
• Not suitable for CDN / dynamic IP network

👉 Related practices:

• 【Deactivate the full process of Wireguard VPN from LetsVPN to self-built (with pit guide)]
• 【Wireguard VPN configuration optimization: domestic website direct connection, foreign traffic go to VPN (actual measurement is effective)]
• 【Wireguard domestic direct connection + foreign tunnel configuration and perfect solution (available for actual measurement)]
• 【Wireguard self-built VPN is unavailable by accident]

🔧 Stage 2: iptables multi-port forwarding (server optimization)

🔧 Architecture optimization

Introduce on the server side:

• iptables multi-port forwarding mechanism

✔ Improve points

Compared to stage one:

• ❌ Don’t modify the WireGuard server port frequently
• ✔ Multiple alternate ports can be configured
• ✔ Quickly switch to restore connection

⚠️ Key changes

When the port is blocked:

👉 Just modify the client port to restore the connection

📌 Essential optimization

❌ Still a problem

• The client still needs to manually change the port
• Splitting still depends on IP rules
• Limited resistance to blockade

👉 Related practices:

• 【Self-built WireGuard solution port is frequently blocked, the ultimate minimalist solution (nanny level can be reproduced)]

🧠 Stage 3: Wireguard + Clash Verge Rev / Flclash (modern shunt scheme)

🔧 Architecture

WireGuard Server（Vultr）
        ↓
Clash Verge Rev / FlClash（客户端）

WireGuard Server（Vultr）
        ↓
Clash Verge Rev / FlClash（客户端）

✔ Core changes

• WireGuard: only responsible for network connection
• Clash: Responsible for intelligent shunting

✔ Advantages

• Supports Domain/GeoSite shunts
• Automatic update rules
• No longer relying on IP segments
• More suitable for CDN network

⚠️ Current Problem (Real Situation)

If the server still uses the phase two structure:

👉 After the port is blocked:

• The client still needs to manually modify the port

❌ Three essential problems of the stage

There are still manual maintenance costs on the client

🧠 Recommended environment for modern diversion schemes

This scheme applies to:

• vultr vps
• or other international cloud servers

👉 Recommended stable nodes for Clash shunts:

• vultr(recommended)
• DigitalOcean (alternative)

👉 Related practices:

• 【ZGoCloud + Wstunnel + Wireguard speed up 4 times, Clash Verge Rev automatically splits and 443 port anti-sealing actual combat]

🚀 Stage 4: ZGoCloud + Wstunnel + Wireguard + Clash (Ultimate Stability Scheme)

🔧 Actual architecture

✔ Compare the core upgrade of stage three

✔ Core advantages

• 443 WebSocket Tunnel
• Reduce port blocking probability
• Long-term stable operation
• Does not depend on frequent port modification

⚠️ Real experience description

It should be noted that:

• WSTUnnel configuration complexity is significantly higher than WireGuard
• Higher client configuration requirements (clash/flclash)
• High initial commissioning costs

But in the long term:

✔ Stability is significantly better than pure Wireguard architecture

🚀 Advanced Stability Program (ZGoCloud)

In scenarios with higher stability requirements, this scheme has been migrated to:

👉 ZGoCloud VPS

Features:

• Multi-regional data centers (Japan / USA / Hong Kong, etc.)
• better network line
• More suitable for long-term stable operation

• Simple
• easy to deploy
• Low cost

🔴 Advanced program (stability priority)

WireGuard + Wstunnel + Clash

WireGuard + Wstunnel + Clash

Features:

• Strong anti-blocking ability
• more stable
• Complicated configuration

💰 Five, Vultr / ZgoCloud use advice

The scheme can be deployed in:

• vultr(Basic plan)
• zgocloud(Advanced Stability Program)

📌 Recommended configuration

• 1 vCPU / 1GB RAM start
• Ubuntu 22.04 / 24.04

🎯 Six, summary

WireGuard itself is fine, but in a modern network environment:

❗ It is more suitable as a ‘transport layer’ rather than a ‘stratch layer’

✔ Final recommended architecture:

• WireGuard: Responsible for the connection
• Clash: Responsible for intelligent shunting
• Wstunnel: Responsible for High Stability Anti-Blocklock (Advanced)
