Cloudflare IP Scanner

Scans for unblocked Cloudflare IPs (currently only WARP CIDRs). Enable it by setting your Wireguard peer server to warp_auto, and also optionally enable port scanning by setting the server_port to 0:

{
            "type": "wireguard",
            "tag": "warp-out",
            "local_address": [
                "10.0.0.2/32"
            ],
            "private_key": "YOUR_PRIVATE_KEY",
            "peers": [
                {
                    "server": "warp_auto",  // <- for WarpInWarp configs set this to the original value `engage.cloudflareclient.com` to disable ip scanner and noise generator for the tunneled warp connection
                    "server_port": 2408,  // <- set to 0 to pick a random WARP port or set it to a fixed port like this to scan endpoints only with this port
                    "public_key": "bmXOC+F1FxEMF9dyiK2H5\/1SUtzH0JuVo51h2wPfgyo=",
                    "allowed_ips": [
                        "0.0.0.0/0"
                    ],
                    "reserved": [
                        80,
                        183,
                        166
                    ]
                }
            ],
            "mtu": 1280
        }

Cloudflare WARP blocking bypass

Bypasses Cloudflare WARP blockings by applying certain Wireguard hacks. Enabled by default for WARP endpoints with warp_auto set as their server field.

TLS clientHello Packet Fragmentation

Fragments TLS ClientHello packets in multiple segments, making it harder to drop connections based on SNI filtering. Enable it by adding the tls_fragment entry to any outbound connection:

...
"outbounds": [
        {
            "type": "direct",
            "tag": "direct"
        },
        {
            "type": "direct",
            "tag": "fragment",
            "tcp_fast_open": false,
            "tls_fragment": {
                "enabled": true,
                "size": "20-100",
                "sleep": "0-2"
            }
        },
...
