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 ``` ## Thanks for free JetBrains Open Source license
