我有一个 OpenWrt 路由器，其 IP 为192.168.1.1我想将所有互联网流量重定向到我的 ssh 隧道，这是我使用的 ssh 命令：
ssh -o "ProxyCommand corkscrew 127.0.0.1 3339 %h %p" -vND 1080 username@serverip
这是我的redsocks.conf，如果有任何问题请纠正：
base {
// debug: connection progress & client list on SIGUSR1
log_debug = on;
// info: start and end of client session
log_info = on;
/* possible `log' values are:
* stderr
* file:/path/to/file
* syslog:FACILITY facility is any of "daemon", "local0"..."local7"
*/
log = stderr;
// detach from console
daemon = off;
/* Change uid, gid and root directory, these options require root
* privilegies on startup.
* Note, your chroot may requre /etc/localtime if you write log to syslog.
* Log is opened before chroot & uid changing.

// login = "foobar";
// password = "baz";
}
redudp {
// `local_ip' should not be 0.0.0.0 as it's also used for outgoing
// packets that are sent as replies - and it should be fixed
// if we want NAT to work properly.
local_ip = 127.0.0.1;
local_port = 10053;
// `ip' and `port' of socks5 proxy server.
ip = 127.0.0.1;

// kernel does not give us this information, so we have to duplicate it

如何使用 redsocks 将我的互联网流量重定向到该 ssh 隧道？我希望它像 openvpn 一样，我只需连接到我的 wifi 并浏览互联网，使用 ssh 隧道时，每次我想将所有互联网流量重定向到该隧道时，我都必须在客户端将代理设置为 socks 端口 1080。我是 linux 新手，我被困在 iptables 命令上，我已阅读说明http://darkk.net.ru/redsocks/但我仍然无法让它工作。请告诉我上面路由器的正确 iptables 命令

我正在使用 transocks，但是 iptables 的配置是相同的：
看起来像这样：https://gist.github.com/andersondanilo/a28e7165fa8a9700d8ead20a224ecf44
您的 redsocks 配置看起来不错。
我的例子是 transocks，但它们的作用是相同的。
transocks 和 redsocks 都会在你的网络上打开一个端口，你可以将所有流量重定向到该端口，redsocks 将重定向到所需的 socks5 代理
对我有用的一个建议的IP表配置是：
#!/usr/bin/bash
# Transocks: https://github.com/cybozu-go/transocks
set -e
stty -echoctl
# Point to the transparent socket port (running in an exclusive user)
TRANSOCKS_PORT=12345
TRANSOCKS_USER=transocks
# Redirect all the network of your computer (except transocks user)
REDIRECT_LOCAL_NETWORK=1
# Redirect access point (wifi hotspot)
AP_SUBNET_ENABLED=1
AP_SUBNET_IFACE=ap0
AP_SUBNET_RANGE="192.168.12.0/24"
