In the modern digital landscape, managing network traffic efficiently across multiple devices is a common challenge. Clash Verge Rev, the successor to the original Clash Verge, offers a powerful feature known as "Allow LAN." This feature allows your primary computer, which is already running a configured proxy, to act as a gateway for other devices on the same local network—such as smartphones, tablets, or gaming consoles. By enabling this, you can bypass the need to install and configure individual proxy clients on every single device, saving time and system resources while ensuring a consistent browsing experience across your entire home or office environment.

Understanding the "Allow LAN" Mechanism

Before diving into the configuration, it is essential to understand what happens when you toggle the "Allow LAN" switch. By default, Clash (the core engine) binds its listening ports (like 7890 for HTTP/HTTPS) to the 127.0.0.1 loopback address. This means only applications running on the same machine can access the proxy. When you enable "Allow LAN," Clash changes its binding address to 0.0.0.0, which instructs the operating system to listen for incoming connections on all available network interfaces, including your Ethernet or Wi-Fi adapter's local IP address.

Pro Tip: Using "Allow LAN" is significantly more battery-efficient for mobile devices compared to running a VPN or a local proxy client on the phone itself, as the heavy lifting of encryption and routing is handled by your desktop.

Step-by-Step Guide to Enabling LAN Sharing

Follow these precise steps to set up Clash Verge Rev as a proxy server for your local network. Ensure you have the latest version of Clash Verge Rev installed to avoid compatibility issues with the core settings.

Step 1: Enable the Feature in Clash Verge Rev

Open your Clash Verge Rev client and navigate to the Settings tab (usually found in the left sidebar). Under the "Clash Core" or "General" section, look for the toggle labeled Allow LAN. Switch this to the "On" position. Once enabled, you might see the "LAN IP" displayed next to the toggle, which is the address other devices will use to connect.

Step 2: Find Your Host Computer's Local IP Address

To connect other devices, you need to know the specific IP assigned to your computer by your router. Even if Clash Verge Rev shows it, it is good practice to verify it manually:

  1. Open the Command Prompt (cmd) on Windows.
  2. Type ipconfig and press Enter.
  3. Look for the "IPv4 Address" under your active connection (e.g., Wireless LAN adapter Wi-Fi). It usually starts with 192.168.x.x or 10.0.x.x.
Warning: If your local IP address changes frequently due to DHCP, your mobile devices will lose the connection. Consider setting a Static IP for your host computer in your router settings.

Step 3: Configure the Proxy on Your Mobile Device

On your iPhone, Android, or other device, go to the Wi-Fi settings and select the network you are currently connected to. Look for "Proxy" or "Modify Network" settings and change the mode from "None" to "Manual." Enter the following details:

  • Server/Hostname: The IPv4 address you found in Step 2.
  • Port: The port number configured in Clash Verge Rev (default is 7890).
  • Authentication: Usually not required unless you manually set a username/password in the YAML config.

Firewall and Security Considerations

One of the most frequent reasons why "Allow LAN" fails is the Windows Defender Firewall. By default, Windows blocks incoming connections on ports it doesn't recognize. When you enable Allow LAN, you must ensure that the Clash core binary (clash-meta or mihomo) is permitted to communicate through the firewall.

If you encounter a connection timeout on your mobile device, try the following:

Action Reason
Allow App through Firewall Ensures Windows doesn't drop incoming packets from the LAN.
Check Network Profile Ensure your Wi-Fi is set to "Private" rather than "Public" in Windows settings.
Verify Port Mapping Ensure no other software (like Skype or local web servers) is using port 7890.

Advanced Customization via YAML

For power users, you can further refine how Allow LAN behaves by editing your configuration file or using the "Merge" feature in Clash Verge Rev. You can specify which IP ranges are allowed to connect or even set up a specific authentication layer to prevent unauthorized users on your Wi-Fi from using your proxy.

Example Config for LAN Security
# Inside your Clash configuration
port: 7890
socks-port: 7891
allow-lan: true
bind-address: "*"
# Optional: Set a password for the proxy
authentication:
  - "user:password"
# Specify which interfaces to listen on
# interface-name: Wi-Fi

Troubleshooting Common Connectivity Issues

If you have followed the steps above and still cannot browse the internet on your secondary device, check these common pitfalls:

1. Subnet Mismatch

Ensure that both the host computer and the mobile device are on the same subnet. For example, if your computer is on 192.168.1.5 and your phone is on 192.168.0.10, they likely cannot communicate directly depending on your router's isolation settings. Guest Wi-Fi networks often implement "AP Isolation," which prevents LAN devices from seeing each other.

2. DNS Leaks and Resolution

Sometimes the proxy connects, but DNS fails. In your mobile proxy settings, ensure you haven't manually set a DNS that conflicts with the proxy's routing. It is often best to let the Clash core handle DNS resolution by ensuring dns: enable: true is set in your profile.

3. Software Conflict

Other VPN software or "Game Boosters" on Windows can hijack the network stack, preventing Clash from correctly binding to the 0.0.0.0 address. Disable any other network-modifying software while troubleshooting the Allow LAN feature.

Conclusion

Enabling "Allow LAN" in Clash Verge Rev is a game-changer for users with multiple devices. It centralizes your proxy management, reduces the complexity of individual device setups, and provides a seamless way to share high-speed, secure connections. By understanding the interaction between the Clash core, your OS firewall, and your local network topology, you can create a robust proxy gateway that serves your entire household. Always remember to keep your host computer secure, as opening ports to the LAN does increase the internal attack surface slightly—only share your proxy on trusted networks.
