### Clash 的配置建议
|
||||
|
||||
请确保 `PROCESS-NAME,ua3f,DIRECT` 置于规则列表顶部，`MATCH,ua3f` 置于规则列表底部。
|
||||
|
||||
可以在 `PROCESS-NAME,ua3f,DIRECT` 与 `MATCH,ua3f` 之间按需加入自定义加密代理规则。如果上述 2 条规则之间加入 DIRECT 规则，请确保匹配该规则的流量属于非 HTTP 协议流量。
|
||||
- Clash 建议选用 Meta 内核。
|
||||
- 请确保 `PROCESS-NAME,ua3f,DIRECT` 置于规则列表顶部，`MATCH,ua3f` 置于规则列表底部。
