同一个客户端配置文件，Windows和Debian都正常，但是在Openwrt中不工作

[oTnTh]

你正在使用哪个版本的 V2Ray？

服务器端：V2Ray 5.2.1 (V2Fly, a community-driven edition of V2Ray.) Custom (go1.19.4 linux/amd64)

v2ray-core下载的v5.2.1 User Preview作为客户端，linux-64和Windows-64均正常。

Openwrt中测试过v2ray-core下载的linux-arm64-v8a，还有Openwrt官方源的5.2.0，表现一致，均不工作。

你的使用场景是什么？

服务器端跑在国外的VPS上，因为IP地址被墙了，所以套了Cloudflare的CDN。服务器端没有套Nginx，直接监听443端口。

配置文件是从这里抄的：https://github.com/v2fly/v2ray-examples/tree/master/VLESS-TCP-TLS-WS%20(recommended)

服务器端和客户端都跑起来以后，用curl测试连接：

curl -vI --socks5-hostname xxxx:1080 https://google.com

你看到的异常现象是什么？

我在config中将loglevel设置为debug，当客户端跑在Windows和Debian中时，服务器端和客户端的STDOUT都有一些连接相关的内容。

但是客户端跑在Openwrt中时，服务器端的STDOUT没有任何输出，似乎客户端的连接请求完全没发到服务器端。

curl的输出是这样的：

curl -vI --socks5-hostname 192.168.1.1:1080 https://google.com
*   Trying 192.168.1.1:1080...
* SOCKS5 connect to google.com:443 (remotely resolved)
* SOCKS5 request granted.
* Connected to 192.168.1.1 (192.168.1.1) port 1080 (#0)
* schannel: disabled automatic use of client certificate
* ALPN: offers http/1.1
* schannel: failed to receive handshake, SSL/TLS connection failed
* Closing connection 0
curl: (35) schannel: failed to receive handshake, SSL/TLS connection failed

都是从v2ray-core下载的程序，服务器端是同一个，客户端的配置文件也完全一样，但是Openwrt中就是不工作。

请附上出错时软件输出的错误日志

服务器端错误日志：

// 服务器端没有输出任何内容

客户端错误日志：

Openwrt系统设置里已经将时区设置为东八区，date命令的输出也是正常的Thu Jan 19 07:43:10 CST 2023，但是日志里的时间戳是UTC时间。可是我用的是VLESS，按照文档的说法，跟时间设置应该没有关系才对？

[oTnTh]

我看到有人提到5.2.0可能存在问题：#2243

于是我将客户端和服务器端都换成了v2ray-core下载的5.1.0，再次测试还是一样的问题。

[oldflag2333333]

openwrt有很多防火墙规则，我觉得你可以看看是不是哪条把他拦了。

[oTnTh]

我用的是Openwrt官方固件，内置的防火墙规则好像也不多，出站什么都没拦，sshtunel和shadowsocks（撞墙之前）都是正常的。/etc/init.d/firewall stop 关闭防火墙以后测试，也还是一样的问题。

比较挠头的是，都看不出应该去哪个部分找问题。

[yyiu]

            "tlsSettings": {
                "serverName": "[域名]"
            },

这个不要了，加了可能会墙

[oldflag2333333]

没仔细看说明，才发现你套了cdn，如果你要用 websocket 的话得确认 cdn 这边是不是支持 websocket，供应商有没有防火墙规则，然后另外 v2ray 报错日志显示的是建立 tcp 连接的时候找不到“目的地”，可能是ipv6之类的原因导致的。

补充一些题外话，如果你要套 cdn 就不要使用 websocket 了，因为 cdn 其实不是解决这个问题的，这种动态请求会回源，而且有可能cdn自己会有些什么规则，让你的 websocket 的表现很奇怪，比如cdn的回源超时时间很短，那么你的 websocket 就会频繁断连。而且就我个人经验来说，一般的 cdn 服务对性能的影响太大了，除非被关了能不套还是不套吧。

[oTnTh]

需要套cdn是因为vps的ipv4地址已经撞墙了，不得已。

至于websocket，则是因为看到了这篇文档：https://guide.v2fly.org/advanced/cdn.html

所以才抄了这里的配置文件：https://github.com/v2fly/v2ray-examples/tree/master/VLESS-TCP-TLS-WS%20(recommended)

我遇到的主要问题是，同一个客户端配置文件，Openwrt上不能用，但是在Openwrt后面的Windows和Debian都正常工作。

[oTnTh]

我自己的ISP是联通，然后我将配置文件发给一个用电信的朋友帮忙测试了一下。在他的Openwrt路由器上，同一个配置文件似乎是能工作的。

但是因为我没法把我的路由器搬到他家里去测试，所以我无法确认这个问题是不是跟ISP相关。
