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

Policies screen in view.
2.
Click the
Port Forwarding
submenu tab.
