透明代理 dns异常

[Ramona22222]

你正在使用哪个版本的 V2Ray？

v5.14.1

你的使用场景是什么？

v2ray透明代理

你看到的异常现象是什么？

异常1. 终端设备dns设置为8.8.8.8，1.1.1.1，等非大陆dns时，出现大量如下警告：

[Warning] [3269249056] app/dispatcher: default route for tcp:b1sync.zemanta.com:443

异常2. 终端设备dns设置为223.5.5.5，192.168.1.254，等大陆dns或任意内网ip时，出现大量如下警告：

[Warning] [3970399347] app/proxyman/outbound: failed to process outbound traffic > proxy/vmess/outbound: failed to find an available destination > common/retry: [dial tcp “vmess服务器地址:端口”: operation was canceled] > common/retry: all retry attempts failed

出现警告时访问所有网站及应用均无问题，同样的配置文件在xray-core下无上述警告

异常1测试：域名“b1sync.zemanta.com”经过其他网络环境多个dns测试下可以解析出ip。rule有完整的ip匹配规则，在当前配置下v2ray并没有解析出此域名的ip，导致走默认出站代理。

异常2测试：添加多个vmess出站配置，并将dns-out的proxySettings分别设置为不同的出站，并将rule下域名和ip匹配规则的出站设置为与dns-out proxySettings相反，发现警告是由dns-out导致的。

你期待看到的正常表现是怎样的？

无警告

请附上你的配置

客户端v2ray配置：

      {

      {

        "ip": ["geoip:!cn"],
        "outboundTag": "proxy"
      }
    ]
  }
}

客户端路由及防火墙配置：

# “helper_lan” 规则容器链，钩子在prerouting，匹配入口设备为br_lan
ip rule add fwmark 50 table 50
ip route add local 0.0.0.0/0 dev lo table 50

nft add rule inet fw4 helper_lan meta nfproto !=ipv4 return
nft add rule inet fw4 helper_lan meta l4proto udp ip daddr { 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8 } udp dport != 53 return
nft add rule inet fw4 helper_lan meta l4proto tcp ip daddr { 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8 } tcp dport != 53 return
nft add rule inet fw4 helper_lan meta l4proto {tcp, udp}  meta mark set 50 tproxy ip to 127.0.0.1:12345 accept

防火墙和v2ray已经劫持了dns流量，为什么终端配置不同的dns会导致不同的异常？

试试解答问题(1) [Warning] [3269249056] app/dispatcher: default route for tcp:b1sync.zemanta.com:443

试试修改 routing

由
      {
        "type": "field",
        "domain": ["geosite:cn"],
        "outboundTag": "direct"
      },
      {
        "type": "field",
        "domain": ["geosite:geolocation-!cn"],
        "outboundTag": "proxy"
      },

到
      {
        "type": "field",
        "domains": ["geosite:cn"],
        "outboundTag": "direct"
      },
      {
        "type": "field",
        "domains": ["geosite:geolocation-!cn"],
        "outboundTag": "proxy"
      },

改: "domain -> domains

试试解答问题(2) [Warning] [3970399347] app/proxyman/outbound: failed to process outbound traffic > proxy/vmess/outbound: failed to find an available destination > common/retry: [dial tcp “vmess服务器地址:端口”: operation was canceled] > common/retry: all retry attempts failed

看是dns不能解释 试试在dns内加入host纪录 如vmess address 是 vps.address.com

    "hosts": {
        "vps.address.com": "x.x.x.x"
    },

@kingwilliam 服务器地址是ip，domain更改为domains依然报错
