Use Clash TUN and Fiddler Everywhere to Capture All Traffic

If you are not familiar with Clash Meta and Fiddler Everywhere, follow the link to learn about them before reading this post.

Basic Thought

• Fiddler Everywhere provide HTTP proxy endpoint
• Clash Meta allow adding HTTP proxy as proxy node

Then we have the following thought:

---
config:
    theme: default
---
flowchart TB
    n4["System Traffics"]
    n4["System Traffics"] --catch all traffic--> A
    n1["Rule Engine"]
    A["Clash Core<br>(TUN Enabled)"] --> n1["Rule Engine"]
    n1 --not from fiddler--> n2["Fiddler<br>HTTP proxy endpoint"]
    n1 --from fiddler--> n3["Internet"]
    n2 -- outgoing data has been treated as general system traffic again --> n4

Rule Settings

First create an HTTP proxy node pointing to Fiddler Everywhere HTTP proxy:

prepend:
  - name: 'Fiddler'
    type: 'http'
    server: '127.0.0.1'
    port: 34567

Based on previous settings, the actual config should be:

prepend:
  - 'PROCESS-NAME,Fiddler.WebUi.exe,🚀 节点选择'
  - 'PROCESS-NAME,Fiddler Everywhere.exe,🚀 节点选择'
  - 'MATCH,Fiddler'

Note that Clash Verge do not allow to choose proxy node like “Fiddler” directly in the UI, you may need to manually enter the node name in advanced edit mode.
