完整性要求

  • 我保证阅读了文档，了解所有我编写的配置文件项的含义，而不是大量堆砌看似有用的选项或默认值。
  • 我搜索了issues，没有发现已提出的类似问题。

我也遇到了在使用REALITY dialerProxy时会出现的问题，不确定是否与此问题同源。
反向代理bridge (VLESS TCP) 通过dailerProxy由Reality代理时，外部访问内部网络会出现断连（bridge设备REALITY outbound断连，触发原因未知，触发随机，推测是连接数多，通常在连续使用一段时间后出现），断连后经过20分钟左右会自动恢复连接。
在之前版本（XTLS VISION）并没有这个问题，应该是在 1.8.0之后出现的问题。
确定1.8.6至1.8.11版本均有此问题。

client bridge (outbound VLESS TCP) --dialerProxy (through outbound REALITY)--> server (inbound REALITY) ----> server portal (inbound VLESS TCP)

环境为旁路由（bridge设备）透明代理
bridge 配置如下

出现断连时bridge日志出现如下报错
Xray_log.txt

同时在断连期间，bridge 设备ping VPS 的 IP 正常
portal VPS 端无此 bridge 连接日志，其他设备（不经过此bridge设备）连接VPS REALITY inbound 正常。

我也遇到相似问题。使用docker pull时不定期出现此报错，使用的xray服务端配置是最简单的代理。

应该修好了 麻烦测试一下最新的构建 https://github.com/XTLS/Xray-core/actions/runs/9072508584
我大体测了一下 感觉 xtls 协议用在客户端的链式代理其实非常好用 因为一般的链式是额外双层加密解密 而 xtls 可以做到连接头双层加密 后面跨两层裸奔 同时两个服务器都是端口转发 非常高效

对性能来说是这样，对“不想让观察者关联两个或多个连接”来说不合适，所以还是不适合 tor，虽然它就多加密几层还是能被关联

对于“不想让观察者关联两个或多个连接”的起夜级需求，我想了下还是只能空跑流量抹平时序特征，like v2ray/v2ray-core#2526 (comment) ，比 hysteria 的 brutal 更激进，不过这样的强特征又不适合过墙了，有点难取舍，好在我没有搞回国流量 ghs 的需求

  1. 已测试 dialerProxy 运作正常
  2. 早前测试的inbound问题也没再出现.

长时间测试後(大约3小时) 先讲测试结果 还是有问题
问题同样出在 dialerProxy tls: bad record MAC

但跟之前不同 今次只是一些情况出现
如一般网页 看网页是没问题 但察看最後那个xray出口error.log 就会有tls: bad record MAC纪录
但如 linux apt http proxy 就一定会有问题

我也遇到了在使用REALITY dialerProxy时会出现的问题，不确定是否与此问题同源。 反向代理bridge (VLESS TCP) 通过dailerProxy由Reality代理时，外部访问内部网络会出现断连（bridge设备REALITY outbound断连，触发原因未知，触发随机，推测是连接数多，通常在连续使用一段时间后出现），断连后经过20分钟左右会自动恢复连接。 在之前版本（XTLS VISION）并没有这个问题，应该是在 1.8.0之后出现的问题。 确定1.8.6至1.8.11版本均有此问题。

client bridge (outbound VLESS TCP) --dialerProxy (through outbound REALITY)--> server (inbound REALITY) ----> server portal (inbound VLESS TCP)

环境为旁路由（bridge设备）透明代理 bridge 配置如下

                "outboundTag": "portal-home1"
            }
            {
                "type": "field",
                "inboundTag": [
                    "realityin"
                ],
                "ip": [
                    "INTERNAL_SERVER_IP"
                ],
                "outboundTag": "portal-home1"
            }
        ]
    }

出现断连时bridge日志出现如下报错 Xray_log.txt

同时在断连期间，bridge 设备ping VPS 的 IP 正常 portal VPS 端无此 bridge 连接日志，其他设备（不经过此bridge设备）连接VPS REALITY inbound 正常。

测试最新1.8.13版本已无此问题。

@kingwilliam 我 ubuntu 本地好久没更新 累积了300多MB 用 http 代理链 更新了半个小时 中间遇到过一次出错 重试就好了 我看了一下貌似不是代理的问题 而且原问题已经修复 所以先关了 如果有可以稳定复现的问题 欢迎再反馈

收到, 我会再留意情况, 谢谢

=====

原问题
client -> server1 -(vless+tcp+reality)-> server2 -(vless+tcp+reality)-> server3

补充 :
client -(http/tproxy)-> server1 -(vless+tcp+reality)-> server2 -(vless+tcp+reality)-> server3

client : 有 android, ios, windows, ubuntu
server1 : 有 Debian 12, ubuntu 22.04
server2 : ubuntu 22.04
server3 : ubuntu 22.04

=====

修改
client -(http/tproxy)-> server1 -(vless+tcp+reality)-> server2 -(vless+tls+grpc)-> server3

如修改
由: server2 -(vless+tcp+reality)-> server3
到: server2 -(vless+tls+grpc)-> server3

tls: bad record MAC 就不会再出现

=====

1.8.13
tls: bad record MAC 问题还存在, 但只会在一些情况出现, 但要详细测试才可给出 出现场景
