### Wyse ThinOS Support To publish applications from the Parallels RAS to thin clients using the Wyse ThinOS, select the Enable Wyse ThinOS Support option on the Wyse tab. Note: The Wyse tab is only available if the gateway mode is set to normal. See Set the Gateway Mode and Forwarding Settings for more info. By enabling this option, the RAS Secure Client Gateway will act as a Wyse broker. You need to make sure that DHCP option 188 on your DHCP server is set to the IP address of this gateway for thin clients that will be booting via this gateway. Once the DHCP server is configured, click the Test button to verify the DHCP server settings.
