就当是笔记啦 ╮(￣▽￣"")╭ 感谢 Project V 及其所有 contributors
下面的脚本唯一 assumed 的是服务器那边 v2ray 开启了 mKCP，具体 assumed 的 mKCP 配置如下
"streamSettings": { "tlsSettings": { "allowInsecure": true }, "security": "none", "kcpSettings": { "header": { "type": "srtp" }, "mtu": 1350, "congestion": true, "tti": 20, "uplinkCapacity": 100, "writeBufferSize": 1, "readBufferSize": 1, "downlinkCapacity": 200 }, "network": "kcp" },
要使用的话，要么改一下自己服务器那边的配置，要么就改一下下面脚本中高亮的部分即可～（总之保持一致就可以( ´▽｀)
用法的话也很简单了，复制下面所有代码到 v2ray-tproxy.sh (或者别的喜欢的文件名也行233333，之后自己替换一下下面的命令，让文件名跟你取的保持一致即可)，
假设你的内网网段是 10.0.1.0/24，v2ray 服务器 IP 是 1.2.3.4，端口是 12345，以及用户 ID 是 12345678-90ab-cdef-1234-567890abcdef 的话，那就执行如下命令～
# 以 root 用户执行下面所有的操作 sudo su # 从官方的脚本安装 v2ray bash <(curl -L -s https://install.direct/go.sh) # 复制后一段的代码到 ./v2ray-tproxy.sh # 然后赋予可执行权限 ./v2ray-tproxy.sh chmod +x ./v2ray-tproxy.sh # 设置 v2ray 透明代理 ./v2ray-tproxy.sh '10.0.1.0/24' '1.2.3.4' '12345' '12345678-90ab-cdef-1234-567890abcdef'
v2ray-tproxy.sh 的内容如下～
