[BUG] Thousands connections when turn on Naive Proxy with TUN

### 操作系统/Operating System Android ### 系统版本/Operating System Version Android 10 ### App版本/App Version [v1.2.20.2304](https://github.com/KaringX/karing/releases/tag/v1.2.20.2304) [v1.2.19.2209](https://github.com/KaringX/karing/releases/tag/v1.2.19.2209) ### 描述/Describeption Hello everybody! Have some troubles with connections on my Android 10 Karing with Naive Proxy. I installed different version of Karing (1.20, 1.22 and last release) and same problem repeat. But on windows 10 or iOS I don`t have this problem with same config Naive Proxy. The problem consist of thousands connections to TUN interface. I tried to change TUN settings but still have problem. If I turn off TUN mode this config doesn\`t work at all. In "connection" section (last photo) I see a lot of connections with tag "com.nebula.karing" and ip_is_private. In Web Panel I see a lot of totally same packets with size 135B and totally same structure: ProxiesConnectionsLogsRulesSettings Connection detailsSource IP labels ` { "chains": [ "direct_out" ], "download": 0, "id": "04265395-cafd-4b8565-34-ea7fc5298dfd", "metadata": { "destinationIP": "[10.20.0.2](https://10.20.0.2/)", "destinationPort": "853", "dnsMode": "normal", "host": "", "network": "tcp", "packageName": "com.nebula.karing", "processPath": "10262", "protocol": "tls", "sourceIP": "[10.20.0.1](https://10.20.0.1/)", "sourcePort": "58634", "type": "tun/tun_in", "user": "" }, "rule": "ip_is_private => route(direct_out)", "rulePayload": "", "start": "2026-06-15T20:59:55.505932074+03:00", "upload": 135, "downloadSpeed": 0, "uploadSpeed": 0 } ` And in logs section I see some errors connect to TUN interface. In service logs only udp errors don`t make sense. Actually time to time this works but often crashes, maybe cause is overfulling RAM. And choosing global/rules doesn\`t work too. <img width="342" height="567" alt="Image" src="https://github.com/user-attachments/assets/693cd6c0-a5c1-46be-9782-6fa3a099e157" /> <img width="345" height="255" alt="Image" src="https://github.com/user-attachments/assets/632e0cf3-cd41-43bb-b813-7a4229cbed97" /> <img width="660" height="281" alt="Image" src="https://github.com/user-attachments/assets/b20e5a9d-abc2-4442-acb5-39a64b864d34" /> ### 复现步骤/Reproduction steps - import Naive config from clipbord (like link naive+https://user:login@server.com:443) - turn on config ### 日志/Log ```shell +0300 2026-06-15 21:15:13 [32191] [4] ERROR naive_client.go:300 outbound/naive[example.space:443]: open UDP connection to [2002:4860:4860::8888]:443: dial wlan0 (33): dial udp [2002:4860:4860::8888]:443: connect: network is unreachable +0300 2026-06-15 21:15:25 [32191] [5] ERROR naive_client.go:300 outbound/naive[example.space:443]: open UDP connection to [2002:4860:4860::8888]:443: dial wlan0 (33): dial udp [2002:4860:4860::8888]:443: connect: network is unreachable +0300 2026-06-15 21:15:28 [32191] [6] ERROR naive_client.go:300 outbound/naive[example.space:443]: open UDP connection to [2002:4860:4860::8888]:443: dial wlan0 (33): dial udp [2002:4860:4860::8888]:443: connect: network is unreachable ```
