Advanced ClashX Configuration Tips: Unleash Maximum Potential

Why Advanced Configuration

While ClashX works out of the box, advanced configuration enables finer control, higher performance, and smarter automation. This article shares practical advanced tips to help you become a ClashX configuration expert.

These tips are suitable for users already familiar with ClashX basics and can significantly improve daily usage experience.

Policy Group Optimization

Understanding Policy Group Types

ClashX supports multiple policy group types, each suitable for different scenarios:

Creating Smart Policy Groups

By combining different policy types, you can build smarter proxy strategies. Here's an example configuration:

proxy-groups:
  # Main selector
  - name: "🚀 Proxy Select"
    type: select
    proxies:
      - 🇭🇰 Hong Kong Node
      - 🇺🇸 US Node
      - 🇯🇵 Japan Node
      - DIRECT

  # Auto SelectHong KongFastest node
  - name: "🇭🇰 Hong Kong Node"
    type: url-test
    url: 'http://www.gstatic.com/generate_204'
    interval: 300
    use:
      - HK-Servers

  # Streaming (Failover)
  - name: "🎬 Streaming"
    type: fallback
    url: 'http://www.gstatic.com/generate_204'
    interval: 300
    proxies:
      - 🇭🇰 Hong Kong Node
      - 🇺🇸 US Node

Policy Group Nesting Tips

Policy groups can be nested to create hierarchical structures:

• First Layer: Group by region (Hong Kong, US, Japan)
• Second Layer: Group by purpose (streaming, gaming, downloads)
• Third Layer: Master controller (manually choose which policy)

Advanced DNS Configuration

DNS Pollution Issues

DNS pollution is a common issue affecting network access. Proper DNS configuration can prevent resolution errors and improve access speed.

Optimizing DNS Configuration

Recommended: use split DNS configuration - domestic DNS for domestic domains, trusted DNS for foreign domains:

dns:
  enable: true
  ipv6: false
  enhanced-mode: fake-ip
  fake-ip-range: 198.18.0.1/16

  nameserver:
    - 119.29.29.29
    - 223.5.5.5

  fallback:
    - tls://1.1.1.1:853
    - tls://8.8.8.8:853

  fallback-filter:
    geoip: true
    geoip-code: CN
    ipcidr:
      - 240.0.0.0/4

fake-ip vs redir-host

Choose the appropriate DNS enhancement mode:

DoH / DoT Encrypted DNS

Use encrypted DNS for enhanced privacy:

• DoH (DNS over HTTPS): Encrypt DNS queries via HTTPS
• DoT (DNS over TLS): Encrypt DNS queries via TLS
• Recommended services: Cloudflare (1.1.1.1), Google (8.8.8.8)

Rule Customization

Rule Priority

Understanding rule matching order is crucial. ClashX matches rules from top to bottom, applying the first matching rule.

Common Rule Examples

Here are some practical custom rules:

rules:
  # Ad blocking
  - DOMAIN-SUFFIX,ads.google.com,REJECT
  - DOMAIN-KEYWORD,analytics,REJECT

  # Force Direct
  - DOMAIN-SUFFIX,apple.com,DIRECT
  - DOMAIN-SUFFIX,icloud.com,DIRECT

  # StreamingRouting
  - DOMAIN-SUFFIX,netflix.com,🎬 Streaming
  - DOMAIN-SUFFIX,youtube.com,🎬 Streaming

  # CN websitesDirect
  - GEOIP,CN,DIRECT

  # Other traffic via proxy
  - MATCH,🚀 Proxy Select

Rule Set References

Using rule sets simplifies configuration and keeps it updated:

rule-providers:
  reject:
    type: http
    behavior: domain
    url: "https://cdn.jsdelivr.net/gh/Loyalsoldier/clash-rules@release/reject.txt"
    path: ./ruleset/reject.yaml
    interval: 86400

  proxy:
    type: http
    behavior: domain
    url: "https://cdn.jsdelivr.net/gh/Loyalsoldier/clash-rules@release/proxy.txt"
    path: ./ruleset/proxy.yaml
    interval: 86400

rules:
  - RULE-SET,reject,REJECT
  - RULE-SET,proxy,🚀 Proxy Select

Automation Configuration

Subscription Conversion Services

Use subscription conversion services to auto-optimize configurations:

• Auto-add rule sets
• Auto-group nodes
• Auto-update configuration
• Custom configuration templates

Configuration Preprocessor

Use ClashX's configuration preprocessing for advanced customization:

script:
  code: |
    def main(params, *args):
      # Auto add latency test
      for group in params["proxy-groups"]:
        if group["type"] == "url-test":
          group["url"] = "http://www.gstatic.com/generate_204"
          group["interval"] = 300
      return params

Scheduled Tasks

Combine with macOS cron or launchd for automation:

• Scheduled subscription updates
• Scheduled node latency tests
• Scheduled configuration backups
• Scheduled log cleanup

Performance Tuning

Reducing Latency

Optimize latency through these configurations:

Reducing Resource Usage

Optimize ClashX resource usage:

• Disable unnecessary logging (log-level: warning)
• Reduce rule count, use rule sets instead
• Disable unused proxy protocols
• Regularly clean cache and log files

Network Optimization
