### Gateway Network Options The Network tab is used to configure RAS Secure Client Gateway network options. Using Site defaults To use Site default settings, click the Inherit default settings option. To specify your own settings, clear the option. For more info, see Site Defaults (Gateways). Configuring network By default RAS Secure Client Gateway listens on TCP ports 80 and 443 to tunnel all Parallels RAS traffic. To change the port, specify a new port in the RAS Secure Client Gateway Port input field. RDP port 3389 is used for clients that require basic load balanced desktop sessions. Connections on this port do not support published resources. To change the RDP port on a gateway select the RDP Port option and specify a new port. When setting your own port, please make sure that the port number does not conflict with the standard "RD Session Host Port" setting. Note: If RDP port is changed, the users need to append the port number to their connection string in the remote desktop client (e.g. [ip address]:[port]). Broadcast RAS Secure Client Gateway Address. This option can be used to switch on the broadcasting of the gateway address, so Parallels Clients can automatically find their primary gateway. The option is enabled by default. Enable RDP UDP Data Tunneling. To enable UDP tunneling on Windows devices, select this option (default). To disable UDP tunneling, clear the option. Client Manager Port. Select this option to enable management of Windows devices from the Client Manager category. The option is enabled by default. Enable RDP DOS Attack Filter. When selected, this option denies chains of uncompleted sessions from the same IP address. For example, if a Parallels Client initiates multiple successive sessions with each session waiting for the user to provide credentials, Parallels RAS will deny further attempts. The option is enabled by default.
