+Only works at client side.

 ### Restriction
 
 There is currently an intended restriction at server side.You cant use tinyFecVPN to access a third server directly. So,as a connection speed-up tool,when used alone,it only allows you to speed-up your connection to your server.You cant use it to bypass network firewalls directly.
