title: R Server on the cloud visit local data on a firewalled office computer
body: <p>I want to use R Server constructed on a Ubuntu system on the Alibaba Cloud to do some elastic computing. The data is on the office computer, which has a firewall to prevent information leaking. I want to update the data to the cloud server for analysis.</p>
  
  <p>I tried WINscp. It won't connect to the server (Connection timeout). I also tried PuTTY, which didn't work, either.</p>
  
  <p>Could this be because of the Firewall?  </p>
