Summary #

Teamviewer is a remote desktop viewing and controlling application. Teamviewer uses port 80 and also checks port 443. When using Teamviewer with SecureSchool, it may be necessary to open port 5938 TCP on the outgoing side. Downloading Teamviewer requires allowing the .exe file from their site. The application communicates on ports 80, 443, and 5938.
