What is FastTunnel?

  • FastTunnel is a high-performance cross-platform intranet penetration tool. With it, you can expose intranet services to the public network for yourself or anyone to access.
  • Unlike other penetration tools, the FastTunnel project is committed to creating an easy-to-extensible and easy-to-maintain intranet penetration framework.
  • You can build your own penetration application by referencing the nuget package of FastTunnel.Core, and target the business extension functions you need.

What can FastTunel do?

  • Remote intranet computer Windows/Linux/Mac
  • Use a custom domain name to access intranet web services (usually used for WeChat development)
  • Port forwarding/port mapping, access services provided by any port on the intranet mysql, redis, ftp, etc.
  • p2p penetration
  • Support binding multiple domain names to access intranet services
  • Support domain name whitelist restriction
  • Support client identity verification

Quickstart

  1. Download the corresponding program on the releases page
  2. Modify the client and server configuration files according to your needsappsettings.json
  3. Run FastTunnel.Server
  4. Run FastTunnel.Cient

Run on Linux/Mac os?

Windows

Double click directly FastTunnel.Client.exe to run

Linux

chmod +x FastTunnel.Client
./FastTunnel.Client

Mac

click directly FastTunnel.Client to run

Configuration example

1. Use a custom domain name to access intranet web services

  • For example, you have a server with a public IP address of 110.110.110.110, and you have a domain name with a top-level domain name of abc.com, you want to visit a website on the intranet by visiting test.abc.com

  • You need to add a DNS resolution for the domain name address, the type is A, the name is *, and the ipv4 address is 110.110.110.110, so that all domain names of *.abc.com will point to 110.110.110.110’s server, because the default http port of FastTunnel is 1270, so you need to visithttp://test.abc.com:1270

  • If you don't want to bring the port number every time you visit, you can use nginx forwarding.

http {
    # add resolver 
    resolver 8.8.8.8;

    # set *.abc.com to 1270 port
    server {
      server_name  *.abc.com;
      location / {
         proxy_pass http://$host:1270;
         proxy_set_header   Host             $host;
         proxy_set_header   X-Real-IP        $remote_addr;
         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
      }

      # 可选
      error_log /var/log/nginx/error_ft.log error;
    }
}
  • If the domain name configured on the server is ft.suidao.io, then access the local site through the subdomain name test.ft.suidao.io:1270, the IIS configuration is as follows: img1

2. Remote intranet computer Windows/Linux/Mac

The client configuration is as follows, there are two hosts in the intranet, and the ip is as follows: appsettings.json

 "ClientSettings": {
    "Common": {
      "ServerAddr": "xxx.xxx.xxx.xxx",
      "ServerPort": 1271
    },
    "SSH": [
      {
        "LocalIp": "192.168.0.100", // linux pc
        "LocalPort": 22,            // ssh default port
        "RemotePort": 12701
      },
      {
        "LocalIp": "192.168.0.101", // windows pc
        "LocalPort": 3389,          // windows default port for Remote
        "RemotePort": 12702
      }
    ]
  }

remote intranet linux host by ssh (ip:192.168.0.100)

Assuming that the user name of the intranet host is root, the server ip is x.x.x.x, and the two hosts that access the intranet are as follows

ssh -oPort=12701 root@x.x.x.x

remote desktop Windows host by mstsc (ip:192.168.0.101)

Controlled terminal setting

  • Open cmd and enter the command sysdm.cpl in the pop-up dialog box and select Allow remote connection to this computer

img1

Control terminal settings

  • Open cmd and enter the command mstsc, open the remote dialog box, enter x.x.x.x:12701 in the computer input box of the dialog box, and then specify the user name and password to remote the windows host of the intranet img1

Development/PR

  • install vs2019 last version
  • install .net5 or higher https://dotnet.microsoft.com/download/dotnet/5.0
  • add test.test.cc 127.0.0.1 in system host file
  • run fasttunnel.server
  • run fasttunnel.client
