Which ports are used by TeamViewer?

來源: Which ports are used by TeamViewer?

teamviewer 用到的 port

 

開放 TCP/UDP Port 5938

開放 *.teamviewer.com

————————————————————————————-

  • TCP/UDP Port 5938: TeamViewer prefers to make outbound TCP and UDP connections over port 5938 – this is the primary port it uses, and TeamViewer performs best using this port. Your firewall should allow this at a minimum.

The following ports are not used by TeamViewer running on Android, Windows Mobile, or BlackBerry.

  • TCP Port 443: If TeamViewer can’t connect over port 5938, it will next try to connect over TCP port 443.Note: port 443 is also used by our custom modules which are created in the Management Console. If you’re deploying a custom module, eg. through Group Policy, then you need to ensure that port 443 is open on the computers to which you’re deploying. Port 443 is also used for a few other things, including TeamViewer update checks.
  • TCP Port 80: If TeamViewer can’t connect over port 5938 or 443, then it will try on port TCP 80. The connection speed over this port is slower and less reliable than ports 5938 or 443, due to the additional overhead it uses, and there is no automatic reconnection if the connection is temporarily lost. For this reason port 80 is only used as a last resort.
