https://community.appian.com/discussions/f/integrations/911/we-recently-got-our-appian-cloud-instances-configured-to-integrate-with-our-vpnWe recently got our Appian Cloud instances configured to integrate with our VPN. Our intention is to be able to write files that were uploaded during a document review process to specific directories on our file server. I&#39;ve looked at the following pageen-USTelligent Community 12https://community.appian.com/thread/3042?ContentTypeID=1Sat, 29 Jun 2013 00:12:59 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:36787c1f-9c60-4ffd-9329-d144a188d5c8danielh366But it might be nice to see an SFTP example use case on the Cloud_VPN_Integration page for future reference, or perhaps a link to the Send_File_Over_SFTP page.<div style="clear:both;"></div>https://community.appian.com/thread/3041?ContentTypeID=1Sat, 29 Jun 2013 00:04:11 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5b10128d-d40e-4599-a75a-b5f9867516f0danielh366FYI, we are working on setting up our server as an SFTP server before I can test the connection.<div style="clear:both;"></div>https://community.appian.com/thread/3034?ContentTypeID=1Fri, 28 Jun 2013 21:17:09 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:1822061a-804e-4ea3-8dfc-1a3b65b644bbelizabeth.epstein1. Send File over SFTP is a good bet for sending files to a remote server. Appian Cloud will not allow you to access a filesystem directly, so you need to use a supported protocol such as SFTP, HTTP(s), or Web Services.<br />2. Any requests that come from your Appian instance, if configured properly with VPN, should make use of the tunnel. If you are getting a 404 or something similar from your smart service, you might want to contact support / make sure that the FTP ports are included.<div style="clear:both;"></div>
