# Network

The **Network** category is used to configure RAS Secure Gateway network options.

To use Site default settings, click the **Inherit Defaults** option. To specify your own settings, clear the option and set the following:

* **RAS Secure Gateway port**: By default RAS Secure Gateway listens on TCP port 80 to tunnel all Parallels RAS traffic. To change the port, specify a new port.
* **RDP port**: 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, make sure that the port does not conflict with the standard "RD Session Host Port" setting.
* **Note:** If the RDP port is changed, users need to append the port number to their connection string in the remote desktop client (e.g. \[ip address]:\[port]).
* **Broadcast RAS Secure 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.
* **Device Manager port**: Select this option to enable management of Windows devices. 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.
