先前讨论：#4966 (comment) ，#4967 (comment)

Xray-core 一直都支持类似于 gost、realm 等软件所谓的“隧道”功能（通过代理协议来端口转发），也就是 dokodemo-door 入站，但是由于当初 v2 起的这个名字不太直观，知道 *ray 还能当“隧道”用的人并不多，导致 dokodemo-door 入站几乎仅用于透明代理

这也提醒各位记得在服务端 block "geoip:private"，防止用户通过代理直接穿透到服务端的内网

现在更名为了 tunnel、设置了些默认值以方便使用，顺便给 freedom 加了别名 direct、blackhole 加了别名 block 以追求直观

Tunnel 的 address 即目标地址默认为服务端的 127.0.0.1/::1，port 即目标端口默认等于本地监听端口，对于多个端口尤其有用：

（146b14a 新增 portMap 配置项，可以按本地监听端口指定走代理后的目标地址/端口，优先级高于原有的 address/port）

// client
{
    "inbounds": [
        {
            "listen": "0.0.0.0",
            "port": "5000-6000,6001",
            "protocol": "tunnel",
            "settings": {
                "network": "", // default: TCP
                "address": "", // default: remote 127.0.0.1
                "port": 0, // default: equals to local listening port
                "portMap": {
                    "5555": "1.1.1.1:7777",
                    "5556": ":8888", // overrides port only
                    "5557": "example.com:" // overrides address only
                }
            }
        }
    ],
    "outbounds": [
        {
            "protocol": "vless",
            "settings": {
            },
            "streamSettings": {
            }
        }
    ]
}
// server
{
    "inbounds": [
        {
            "listen": "0.0.0.0",
            "port": 443,
            "protocol": "vless",
            "settings": {
            },
            "streamSettings": {
            }
        }
    ],
    "outbounds": [
        {
            "protocol": "direct",
            "settings": {
                "redirect": ""
            }
        }
    ]
}

通过以上配置即可简单地把客户端的 IPv4/TCP/5000-6001 端口通过 VLESS 协议转发到服务端相应的 IPv4/TCP/5000-6001 端口

当然你也可以设置 tunnel 入站 settings 的 address/port 或 direct 出站的 redirect 以强制覆写目标地址或端口，或都覆写

（特别地，由 tunnel 入站 5555 端口接收的流量会通过 VLESS 协议转发到 1.1.1.1:7777，优先级高于原有的 address/port）

@Fangliding 文档里写的 network 默认 TCP，但我看代码中似乎会炸？你测试下

总之你测试下示例配置能不能直接跑吧，没问题的话我就合了

还有如果出站是freedom的话自己倒自己会无限回环

可以跑就行，真正使用时客户端和服务端是分开的，不会无限回环

有点想加个配置项 portMaps，可以指定把 "5500" 端口映射到 "7000" 这种

很久以前写过这种恶趣味功能 输入一个公式 然后计算 RemotePort = f(LocalPort) mod 65536

大佬，请问如果转发的端口设置为1-65535，xray现在是可以直接当gateway使用了吗？

这和三层的gateway可不是一个东西啊。。

@RPRX

I use this new alias for serverless-for-Iran to force clients use latest version, to benefit from the latest features and bug fixes.

///

also, I think adding minVersion option in config to force clients to use version>=minVersion.

what's your idea?

这个我也想过，可以做，你写吧

因为以后出配置订阅肯定要加 minVersion，现在加也行，顺便你加个 maxVersion 吧，因为有些配置只适用于特定时期的 Xray

Should it be added to ‍‍policy settings?

加在根配置吧，policy 有本地策略不太能被订阅
