Use the local configuration file config.ini

The config.ini example can also be  downloaded directly (right click and save as) and then modified by yourself (note, windows users, download the windows version  here )

#将本文件放置于natapp同级目录 程序将读取 [default] 段
#在命令行参数模式如 natapp -authtoken=xxx 等相同参数将会覆盖掉此配置
#命令行参数 -config= 可以指定任意config.ini文件
[default]
authtoken=                      #对应一条隧道的authtoken
clienttoken=                    #对应客户端的clienttoken,将会忽略authtoken,若无请留空,
log=none                        #log 日志文件,可指定本地文件, none=不做记录,stdout=直接屏幕输出 ,默认为none
loglevel=ERROR                  #日志等级 DEBUG, INFO, WARNING, ERROR 默认为 DEBUG
http_proxy=                     #代理设置 如 http://10.123.10.10:3128 非代理上网用户请务必留空

Note:

 http_proxy is used for users who cannot directly access the Internet and need to go through a proxy to access the Internet. For other users, please leave blank

Old versions of windows such as windows xp and other old versions of windows server do not support this method, please use the command line method

command line mode 

 Run natapp -h to see the command line parameters. The parameters are synchronized with config.ini as described above. The command line mode will overwrite the same parameters in config.ini

The command line parameter -config= can specify any config.ini file  

Multi-open method

Windows can create a bat file  to download (right click and save as)

start natapp -authtoken=xxxx
start natapp -authtoken=xxxx

Put the bat file in the same directory as natapp.exe and modify the authtoken, double-click to run the bat to open two or more natapps at the same time

For other systems, such as linux, etc., you can create a shell by yourself
