由nekoray魔改的v2ray-core在NAT Type Test中呈现UnsupportedServer

[NekoCompiler]

描述问题

预期行为：

由于V2Fly的v2ray-core在v5版本之后解决了VMess的UDP FullCone问题，所以实际上服务器和客户端只要都是≥5.0.0版本是可以达到FullCone NAT效果的。

实际行为：

在nekoray的魔改v2ray-core中无法实现这种效果，测试为UnsupportedServer。❌ 在nekoray的魔改sing-box中可以实现这种效果，测试为FullCone。✅ 在Matsuri的魔改v2ray-core中可以实现这种效果，测试为FullCone。✅

如何复现

服务器版本为v2fly/v2ray-core v5.1.0，nekoray版本为v2.5

在服务器中这样设置 (v2ray JSONv5格式) (vmess websocket with nginx tls)

{
  "log": {
    "access": {
      "type": "File",
      "path": "/var/log/v2ray/access.log"
    },
    "error": {
      "type": "File",
      "path": "/var/log/v2ray/error.log",
      "level": "Warning"
    }
  },
  "inbounds": [
    {
      "listen": "127.0.0.1",
      "port": 2001,
      "protocol": "vmess",
      "settings": {
        "users": [
          "你的UUID"
        ]
      },
      "streamSettings": {
        "transport": "ws",
        "transportSettings": {
          "path": "/你的Path",
          "maxEarlyData": 1024
        },
        "security": "none"
      }
    }
  ],
  "outbounds": [
    {
      "protocol": "freedom",
      "settings": {}
    }
  ]
}

在nekoray中这样设置

Nekoray (V2Ray) 结果 (使用Socks端口测试)

NekoBox (sing-box) 结果 (使用Mixed端口测试)

Matsuri结果 (使用VPN测试)

无法复现，v2ray packet 测得 full cone，请检查服务器配置
