关于HarmonyOS 鸿蒙Next VPN路由
我的手机系统是harmonyos next，手机连接的是wifi，用的是官方vpn的demo进行测试。

vpn demo跑通后，遍历所有的网络信息，共获取到两条记录（一条wifi，一条vpn），如下：

第一条：

{
  "linkUpBandwidthKbps": 0,
  "linkDownBandwidthKbps": 0,
  "networkCap": [12, 15, 16],
  "bearerTypes": [1]
}

{
  "interfaceName": "wlan0",
  "domains": "",
  "mtu": 1500,
  "linkAddresses": [
    {
      "address": "172.28.143.155",
      "family": 1,
      "port": 0
    }
  ],
  "routes": [
    {
      "interface": "wlan0",
      "destination": {
        "address": "0.0.0.0",
        "family": 1,
        "port": 0
      },
      "gateway": {
        "address": "172.28.159.254",
        "prefixLength": 0
      },
      "hasGateway": true,
      "isDefaultRoute": false
    }
  ],
  "dnses": [
    {
      "address": "114.114.114.114",
      "family": 1,
      "port": 0
    }
  ]
}

第二条：

{
  "linkUpBandwidthKbps": 0,
  "linkDownBandwidthKbps": 0,
  "networkCap": [11, 12, 16, 31],
  "bearerTypes": [4]
}

{
  "interfaceName": "vpn-tun",
  "domains": "",
  "mtu": 1400,
  "linkAddresses": [
    {
      "address": "10.0.0.5",
      "family": 2,
      "port": 0
    }
  ],
  "dnses": [
    {
      "address": "114.114.114.114",
      "family": 0,
      "port": 0
    }
  ]
}

另外我的目的是访问内网172.21.21.128上的9090端口，我配置的vpnconfig中的routes如下： 我的vpn server物理ip 172.21.21.199/24，vpn server 虚拟网卡ip 10.0.0.10/24，我的vpn client 隧道ip 10.0.0.5，且vpn server到172.21.21.128的9090端口是通的。

interface: "vpn-tun",
  destination: {
    address: {
      address: '172.21.21.128',
      family: 1,
      port: 9090
    },
    prefixLength: 32
  },
  gateway: {
    address: '10.0.0.10',
    family: 1,
    // port: 8888
  },
  hasGateway: true,
  isDefaultRoute: false,

为什么我在手机浏览器中访问172.21.21.128:9090业务失败，另外可以看到我的vpn中网络信息感觉也有问题，为什么family会是2（IPv6），并且没有routes字段，另外我想问下我的vpnconfig中的routes路由到底该怎么配置？
