+# Sample
+如把本机的:4455的UDP流量转发到www.yourserver.com:4455：For example, the UDP traffic of the machine: 4545 is forwarded to www.yourserver.com:4455:
+* 在www.yourserver.com的服务器上用root权限运行。Run with root privileges on the server at www.yourserver.com
+```
+sudo ./pingtunnel -type server
+```
+* 在你本地电脑上用管理员权限运行。Run with administrator privileges on your local computer
+```
+pingtunnel.exe -type client -l :4455 -s www.yourserver.com -t www.yourserver.com:4455
+```
