Creating a Listener

Fudo One allows creating a Listener, based on RDP, SSH or VNC protocol.

Creating an RDP listener

In order to create an RDP Listener, follow the instruction:

1. Click + icon in the main menu next to the Listeners tab, or

📘

Security mode must match the security mode setting in the RDP server configuration.

• If the Enhanced RDP Security (TLS) option is chosen, select Legacy ciphers option to allow negotiating older encryption algorithms (DSA(1024), RSA(1024)) when establishing RDP connections.

6. In the Announcement field, type in the announcement that will be presented to the user on the login screen.
