frsocks+protoplex+流量重定向,实现端口复用

frsocks

https://github.com/3gstudent/Homework-of-Go/blob/master/frsocks.go

监听本地的2333端口开启一个socks5代理，这里也可以用其他工具，如ew，frp等等。

./frsocks -sockstype fsocks -listen 2333

protoplex

https://github.com/Pandentia/protoplex

这是一个协议复用的工具，比如命令可将本地9999端口的流量根据协议类型转到本地的2333和80端口。

注: 在实战环境中，先用protoplex进行分流，然后再进行重定向。

./protoplex --socks5 192.168.154.130:2333 --http 127.0.0.1:80 -b 192.168.154.130:9999

注: protoplex设置分流的http协议IP和重定向的ip不要设置为同一个ip,否则会形成闭环。

同时该工具还支持其他协议的分流，如：

• SSH
• HTTP
• TLS (/ HTTPS)
• OpenVPN
• SOCKS4 / SOCKS5

流量重定向

linux

将访问80的流量重定向到9999端口

sudo iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9999

windows

将本地80流量重定向到9999

netsh interface portproxy add v4tov4 listenport=80 listen address=192.168.154.129 connectport=9999 connectaddress=192.168.154.129

相关操作命令：

显示系统中的转发规则列表：

netsh interface portproxy show all

删除指定的端口转发规则：

netsh interface portproxy delete v4tov4 listenport=80 listenaddress=192.168.154.129

清除所有当前的端口转发规则：

netsh interface portproxy reset

注: 必要的情况下，可以设置特定来源ip进行流量重定向。

A protocol multiplexer in Go.

protoplex

An application protocol multiplexer

What is this?

In a nutshell, this application lets you run multiple kinds of applications on a single port. This is useful for, for instance, running an OpenVPN server and a TLS/HTTPS server on port 443, which in turn is useful for evading firewalls that block all other outbound ports.

Running

Native

Assuming you have a properly configured Go setup, get and compile the multiplexer with

go get github.com/Pandentia/protoplex/cmd/protoplex

and then run it with (for example, to run SSH and HTTPS)

protoplex --ssh your_ssh_host:22 --tls your_webserver:443

Protoplex is now running on port 8443 and ready to accept connections.

For more extensive configuration, please see the output of --help.

Goals

The concepts for this multiplexer were as follows:

• Resource usage about on par with sslh
• Easily extensible
• Highly dynamic

To this end, protoplex supports multiple matching methods for protocols:

• Bytestring comparison
• Regex matching

These can both be implemented for a protocol, with bytestrings taking priority (due to efficiency). In addition, protocols support matching limits, reducing the amount of protocols evaluated for a given handshake.

Protocol support

Currently supported protocols are:

• SSH
• HTTP
• TLS (/ HTTPS)
• OpenVPN
• SOCKS4 / SOCKS5

Feel free to file an issue on the GitHub repository if you want a protocol to be supported. Please include steps to accurately reproduce your client setup.

Alternatively, you may submit a pull request.
