[QUESTION] Only listen on ipv6

[bart3nder]

Hi! Thanks for the examples. As the title says, In TUIC server config, how can I only listen on ipv6? with "listen": "::",, I can still connect to server with my ipv4 too and I want the server only be accessible via ipv6.

"listen": "[::]",

"listen": "::1",

This is the answer given by the asking AI, you tested it.

Hello again, Sorry for late response. Seems the second one doesn't give syntax error, but when I use it I can no longer connect to server; like:

+0000 2023-09-13 09:36:13 INFO router: loaded geosite database: 1391 codes
+0000 2023-09-13 09:36:13 INFO router: updated default interface eth0, index 2
+0000 2023-09-13 09:36:13 INFO inbound/tuic[tuic-in]: udp server started at [::1]:443
+0000 2023-09-13 09:36:13 INFO sing-box started (0.77s)

And nothing will happen. Once I change to "listen": "::",, I can connect via ipv6 as before. Why is this happening? How can I fix it? My server config:

  "inbounds": [
    {
        "type": "tuic",
        "tag": "tuic-in",
        "listen": "::1",
        "listen_port": 8448,
        "users": [
            {
                "name": "beta",
                "uuid": "beta", 
                "password": "beta"
            }
        ],
        "congestion_control": "bbr",
        "auth_timeout": "4s",
        "zero_rtt_handshake": false,
        "heartbeat": "6s",
        "tls": {
            "enabled": true,
            "alpn": [
                "h3",
                "spdy/3.1"
            ],
            "certificate_path": "MYREALCERTPATH",
            "key_path": "MYREALKEYPATH"
        }
    }
  ],

I suggest you go to sing-box's github and ask a question. I can't help you any further.
