Feature Request: Allow Manually Skipping a Matched Route Rule and Continue Matching

[Lihewin]

Why

In sing-box, route rules are strictly terminal: once a rule matches, routing stops.

Current mechanisms (selector outbound or clash_mode) only allow switching outbounds or modes, but do not allow temporarily disabling a rule itself or letting traffic continue matching subsequent rules.

This makes some common routing scenarios unnecessarily complex and inflexible.

Example: SSH Rule That Should Be Temporarily Bypassable

Route Configuration (Current)

{
  "route": {
    "rules": [
      {
        "protocol": "ssh",
        "outbound": "current_selector"
      },
      {
        "ip_cidr": ["A"],
        "outbound": "A"
      },
      {
        "ip_cidr": ["B"],
        "outbound": "B"
      },
      {
        "ip_cidr": ["/*some conditions*/"],
        "outbound": "ts-out"
      },
    ]
  }
}

{
  "outbounds": [
    {
      "type": "selector",
      "tag": "ssh_selector",
      "outbounds": ["A", "B", "ts-out", "reject"]
    }
    // ... some outbounds
  ]
}

Current Behavior

• All SSH traffic always matches the first rule
• The selector can only choose a fixed outbound
• SSH traffic cannot fall through to later rules
• To “disable” the SSH rule, users must duplicate routing logic inside the selector

---

Desired Behavior

If a special skip / bypass outbound (or equivalent mechanism) existed:

{
  "type": "bypass"
}

Then the selector could expose:

{
  "type": "selector",
  "tag": "ssh_selector",
  "outbounds": ["ssh_proxy", "bypass"]
}

Behavior:

• Selecting ssh_proxy → SSH-specific routing
• Selecting bypass → ignore the SSH rule and continue matching:

Use Cases

• Temporarily disabling protocol- or port-based rules
• Debugging routing behavior via clash API
• Avoiding duplicated downstream rules
• Fine-grained runtime control beyond clash_mode
