To add a RAS Secure Gateway:
Navigate to Infrastructure > Secure Gateways.
In the right pane, choose Add from the ellipsis menu. The Gateway - Add new wizard opens.
Enter the server FQDN or IP address or click Browse AD to select a server from the list. To resolve IP address to FQDN or vice versa, click Resolve IP or Resolve Name.
Click Next.
Select the gateway mode from the Mode drop down menu (Normal or Forwarding).
If you selected the Forwarding mode in the previous step, select the destination gateway in the Forward to drop-down list. You can also select a specific IP address in the On IP drop-down list if the Gateway server has more than one.
Add an optional description for this Gateway.
Select the Enable User Portal option to enable the RAS User Portal support (a browser-based client that can be used to connect to Parallels RAS and launch published resources).
Select the Enable firewall rules to automatically configure the firewall on the server hosting the gateway.
Click Next.
Review the settings and click Create to add the Gateway to the Site.
