a. Users can specify the port number together with the host name or IP address.

4.Click the Add table button. The new application entry is added to the List of Configured Applications for Port Forwarding table. Remote users can now securely access network applications once they have logged into the SSL VPN portal and launched port forwarding.

To delete an application from the List of Configured Applications for Port Forwarding table, select the checkbox to the left of the application that you want to delete, and then click the Delete table button in the Action column.

Adding A New Host Name

After you have configured port forwarding by defining the IP addresses of the internal servers and the port number for TCP applications that are available to remote users, you then can also specify “host-name-to-IP-address-resolution” for the network servers as a convenience for users. Host name resolution allows users to access TCP applications at familiar addresses such as mail.example.com or ftp.customer.com rather than by IP addresses.

To add servers and host names for client name resolution:

1.Select VPN > SSL VPN from the menu. The SSL VPN s submenu tabs appear, with the Policies screen in view.

2.Click the Port Forwarding submenu tab. The Port Forwarding screen displays (see Figure 8-14 on page 8-23).
