What network ports are used for uploading file attachments in Smartsheet

John Russo

I want to be able to block the network ports in my firewall to prevent a user from being able to attach a file to smartsheet. If not ports, then what is it connecting to on the other side and I can block that. I have the Team plan, and unlike the Enterprise plan, does not give me the control to restrict/block that function.

 

Thank you.

The varous attachment providers do not use any special ports. So the only sure way to prevent users from using attachments is to use the File Attachment Options which is only available to Enterprise accounts. You might be able to prevent users from using the Google Drive, OneDrive, Dropbox, Box, Evernote, & Egnyte attachment providers by blocking users' requests to the DNS/domains that those services use, but I'm not sure how comprehensive that will be and the users might see unexpected error messages. That will also impact those services outside of Smartsheet as well. You'd have to consult documentation or support for each of those services to find out exactly which domains that they use or to see if they offer any other options for blocking access to their services.
