Block the Teamviewer connection from outside to a specific computer

FreddyC — Fri, 01 Mar 2024 05:04:35 GMT

Hello! Is it possible to block a user from using Teamviewer whether he or she is on a personal laptop or mobile device using the Teamviewer app to remote/connect to a specific computer inside the corp network? HR has asked to block any outside connection so the end-user cannot use any more Teamviewer from the outside world to remote to a specific PC (in the trust zone) to clock in early. If so, kindly provide high-level steps, please.

Thanks!

teamviewer establishes an outbound connection to their infrastructure in the cloud. if you block outbound teamviewer, the workstation is no longer able to connect out and become available for remote control

if you want to go a step further (because users will likely start searching for alternatives) you can create an application filter and select subcategory remote-access so all app-ids that enable remote control are selected, then block outbound connections to this application filter object

Hi @FreddyC ,

In addition to what @reaper mentioned, the following KB confirms that blocking outbound Teamviewer connections will block the inbound connections:

Can Inbound TeamViewer Connections be Blocked while Allowing Outbound Access?

Kind regards,

Hello @reaper @kiwi
I have a use case where i want to block access from Personal PC to Corporate PC, so corp PC can still remote access to other PCs but outside corp users should not be able to remote into corp PCs
Please advise!
