  1. Connect to the SSL VPN and Confirm the Public IP route is installed using the Route Print command on the user's machine
  2. SSL VPN users will be able to access only the specific public IP and  Internal network using the VPN Tunnel.
  3. Also, it is possible to add an address object that consists of addresses of the particular domain, for example, Facebook.
