树莓派刷原生OpenWRT 安装V2ray作为旁路由（网关或透明代理）让全屋免配置走代理

7 月 8, 2020

由

ITGeeker之前有配置过OpenWRT使用SS+ChinaDNS+DNS-Forwarder来做代理：

虽然obfs混淆不被ss支持了，但使用起来还是没有问题的。不过最近服务器支持V2ray了，所以又用OpenWRT配置了V2ray的透明代理，或者说是网关，ITGeeker喜欢把它叫成旁路由，你喜欢怎么称呼都可以，技术奇客这里安装再旁路由器里，就称旁路由了。

先来个简化的拓扑图，具体配置图文的确比较繁杂，看的懂下面的完整配置文件的应该可以自己配置。有需要图文说明的请留言将优先更新。

V2ray其实相当于打包了好多上面的应用，安装起来比较方便，功能强大了很多，但配置起来却不是更方便，幸亏openwrt版的预先内置配置很有用。

完整配置文档

来自/var/etc/v2ray/v2ray.main.json文件，我这里配置了6个自有的outbond服务器，4个v2ray+2个ss。只要替换上你自己的服务器地址、ID、alterId、security或者SS的密码，理论上就可自动实现代理了。

在V2ray的全局设置中，设置config文件应该可以实现，但还未亲自测试。

防火墙iptables配置

命令行输入执行或者添加到OpenWrt 管理界面面 Network -> Firewall -> Custom Rules

ipset -N gfwlist iphash
iptables -t nat -A PREROUTING -p tcp -m set --match-set gfwlist dst -j REDIRECT --to-port 1081
iptables -t nat -A OUTPUT -p tcp -m set --match-set gfwlist dst -j REDIRECT --to-port 1081
ipset add gfwlist 8.8.8.8

开启UDP需要 iptables-mod-tproxy 模块，请确保已经安装好。

opkg install iptables-mod-tproxy

OpenWRT dnsmasq-full配置

可参考：OpenWRT dnsmasq-full配置

cd /etc/dnsmasq.d && wget https://cokebar.github.io/gfwlist2dnsmasq/dnsmasq_gfwlist_ipset.conf

#若下载错误，请安装
opkg install libustream-mbedtls coreutils-base64 ca-certificates ca-bundle

这里我们需要把dnsmasq_gfwlist_ipset.conf里类似server=/hp.com/127.0.0.1#5353的行全部删除，在win10可用vsc等编辑软件，正则搜索

server=/(.*)

替换为空就行。记得

# 重启dnsmasq
/etc/init.d/dnsmasq restart

dnsmasq-china-list安装（可选）

作为前置优化国内外网站用，请参考官方发安装方法，国内外各大代码网站都有他们的官方代码：

V2ray透明代理的问题解决

如果重启主路由和旁路由了还不能上网，可以按以下方式检查：

旁路由配置是否正确？可以参考

刷了OpenWRT的路由器+旁路由配置方法+无缝漫游配置（树莓派3B/3B+/4B使用OpenWRT系统做旁路由）

旁路由是否开启 IP 转发？

echo "net.ipv4.ip_forward=1" >> /etc/sysctl.d/10-default.conf
sysctl -p

测试旁路由自身是否可以通过代理上网？

curl -x socks5://127.0.0.1:1080 google.com

结果应为：

<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
<A HREF="http://www.google.com/">here</A>.
</BODY></HTML>

再检查一遍iptables命令是否被正确执行？
还不行，找个高手指导一下吧

这里用的是redirect的方式走代理，不支持ipv6，据说tproxy的方式可以支持ipv6
