G DATA 365 | Mail Protection

Which port authorisations do I have to observe?

For a seamless retrieval of the portal information from our backend, it is essential that the outgoing port 2675/TCP is available.

Should there be any display issues when retrieving the information in the G DATA Web-Portal, kindly verify your firewall settings. In the event that the connection is unsuccessful, an error message will be displayed.

You can test the connection with Telnet, for example:

Telnet mailprotection.gdata.de 2675

If the connection is established correctly, you will see a flashing cursor. Otherwise an error message will be displayed.
