+
+## Note: This tool is only to be used for study and research, do not use it for illegal purposes
+

+
+## Usage
+
+### Install server
+
+-   First prepare a server with a public IP, such as EC2 on AWS, assuming the domain name or public IP is www.yourserver.com
+-   Download the corresponding installation package from [releases](https://github.com/esrrhs/pingtunnel/releases), such as pingtunnel_linux64.zip, then decompress and execute with **root** privileges
+-   “-key” parameter is **int** type, only supports numbers between 0-2147483647
+
+```
+sudo wget (link of latest release)
+sudo unzip pingtunnel_linux64.zip
+sudo ./pingtunnel -type server
+```
+
+-   (Optional) Disable system default ping
+
+```
+echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
+```
+
+### Install the client
+
+-   Download the corresponding installation package from [releases](https://github.com/esrrhs/pingtunnel/releases), such as pingtunnel_windows64.zip, and decompress it
+-   Then run with **administrator** privileges. The commands corresponding to different forwarding functions are as follows.
+-   If you see a log of ping pong, the connection is normal
+-   “-key” parameter is **int** type, only supports numbers between 0-2147483647
+
+
+#### Forward sock5
+
+```
+pingtunnel.exe -type client -l :4455 -s www.yourserver.com -sock5 1
+```
+
+#### Forward tcp
+
+```
+pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455 -tcp 1
+```
+
+#### Forward udp
+
+```
+pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455
+```
+
+### Use Docker
+It can also be started directly with docker, which is more convenient. Same parameters as above
+-   server:
+```
+docker run --name pingtunnel-server -d --privileged --network host --restart=always esrrhs/pingtunnel ./pingtunnel -type server -key 123456
+```
+-   client:
+```
+docker run --name pingtunnel-client -d --restart=always -p 1080:1080 esrrhs/pingtunnel ./pingtunnel -type client -l :1080 -s www.yourserver.com -sock5 1 -key 123456
+```
