Chapter72 Configuring Clientless SSL VPN
Configuring Remote Systems to Use Clientless SSL VPN Features
2. In the Name column, find the name of the server you want to use, then identify its corresponding
client IP address and port number (in the Local column).
3. Use this IP address and port number to configure the client application. Configuration steps vary for
each client application.
Note Clicking a URL (such as one in an -e-mail message) in an application running over a clientless
SSL VPN session does not open the site over that session. To open a site over the session, paste
the URL into the Enter Clientless SSL VPN (URL) Address field.
Using E-mail Via Port Forwarding
To use e-mail, start Application Access from the clientless SSL VPN home page. The mail client is then
available for use.
Note If you are using an IMAP client and you lose your mail server connection or are unable to make a new
connection, close the IMAP application and restart clientless SSL VPN.
Prerequisites
You must fulfill requirements for application access and other mail clients.
Restrictions
We have tested Microsoft Outlook Express versions 5.5 and 6.0.
Clientless SSL VPN should support other SMTPS, POP3S, or IMAP4S e-mail programs via port
forwarding, such as Lotus Notes and Eudora, but we have not verified them.
Using E-mail Via Web Access
The following e-mail applications are supported:
•Microsoft Outlook Web App to Exchange Server 2010.
OWA requires Internet Explorer 7 or later, or Firefox 3.01 or later.
•Microsoft Outlook Web Access to Exchange Server 2007, 2003, and 2000.
For best results, use OWA on Internet Explorer 6.x or later, or Firefox 3.x.
•Lotus iNotes
Prerequisites
You must have the web-based e-mail product installed.
Restrictions
Other web-based e-mail applications should also work, but we have not verified them.
