Please consult the product documentation for more details. Feature Remote Upgrade Support Support for Microsoft Outlook Anywhere Extended SSO Support Windows Security Center Traffic Recording Advanced Password Policies Contextual Session Control Description It is now possible to update SSL VPN Gateways through the StoneGate Management Client. With SSL VPN 1.3, end users can synchronize their Microsoft Outlook , calendar, and contacts without any need to install an Access client. By securing the RPC communication with SSL, the SSL VPN 1.3 provides end users seamless, quick, and secure access to their e- mail, without the hassle of distributing, installing, and maintaining a third party VPN. From version 1.3, SSL VPN supports strong authentication with single sign-on for Telnet and SSH connections. In addition, StoneGate SSL VPN provides SSO for a wide range of applications, such as Windows Fileshare, Microsoft Terminal Server, Citrix Web Interface, Microsoft Sharepoint Portal, and Outlook Web Access. Using a plug-in, the Windows Security Center can be used to determine the security status of the client device before allowing access. The plug-in is included in the installation package. SSL VPN 1.3 Traffic Recording enables you to record any transaction between a user and the target system. SSL VPN 1.3 enables administrators to configure more advanced password policies to restrict how passwords are set and reset, for example, to disallow specific combinations of characters in a password. The growing adoption of intranet security domains calls for a new view on session time-outs that caters for users connecting in different contexts, such as from their assigned desktop or a guest desktop.

6 SUSE Linux Enterprise Server 10 Sun Java Runtime Environment or later Additionally, when using the Access Client on Windows Vista, the following requirements apply: Requirement Access Client on Microsoft Windows Vista requires administrator rights StoneGate ActiveX Client Loader requirements Drive letter mapping in Windows Vista Remove AES cipher suites from Access Point configuration Java Runtime Environment Details The Access Client requires administrator rights to run properly on Windows Vista. To run the ActiveX Access Client loader successfully with Windows Vista UAC, you must add the Access Point server https address to the list of trusted sites in Internet Explorer. A single drive letter (for example, F:) cannot be used as a startup command in Windows Vista. All commands must be executed using runas to elevate to administrator mode since the mapping is done in administrator mode, and F: is not a valid executable. Use the following startup command instead: explorer /root, F: This works on both Windows XP and Windows Vista. The AES ciphers in Vista are not compatible with the SSL engine used in Access Point. You must remove the AES ciphers from Cipher Suites for your Access Point under Manage Global Access Point Settings. Remove the following ciphers: RSA_AES_128_CBC_SHA and RSA_AES_256_CBC_SHA. To run the PortWise Java Access Client, use Sun Java 1.6 Update 2 or later. 6 StoneGate SSL VPN Release Notes for version 1.3.0
