3 What s New Fixes Problems described in the table below have been fixed since StoneGate SSL VPN v A workaround solution is presented for earlier versions where available. Synopsis Assessment plugins are now included (#32617) Using internal LDAP for user storage may fill the file system (#41322) Creating backup may fail because of insufficient disk space (#44655) Internal LDAP generates error messages when it is not used (#45926) Administration service may not start in slow systems (#46113) SSL VPN may not allow enough concurrent connections (#47035) Cannot change password with sgreconfigure if password contains special characters (#47087) Description Some assessment plugins have been missing from the system. Plugins "Antivirus", "Sygate On Demand", "Mac", and "SecurityCenter" are now included by default. Using internal LDAP for user storage in a large system or in any system for a long time may fill the /data partition in the file system with OpenLDAP log files. Creating a backup with the command "sg-backup --includespool" may fail if the log spool has a lot of log files. When internal LDAP is not used for directory or user storage services, the slapd process generates error messages in SSL VPN logs. This does not affect SSL VPN usage. If the system is slow, the timeout for waiting for the Administration service to start may be too short. This prevents logging into the StoneGate SSL VPN Administrator (the connection is refused). If users open a lot of connections to different resources, SSL VPN may not allow enough concurrent connections. The users may see error messages like " Proxy error: Could not connect to host "Resource name". errno: 24, HttpBrowser info= ". Changing the Web Console password with sg-reconfigure fails if the password contains special characters. Workaround for previous versions Use external user storage as recommended. Ignore the error messages. 3 StoneGate SSL VPN Release Notes for version 1.2.1

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 1.2.1

9 Known Issues The current known issues of StoneGate SSL VPN v1.2.1 are described in the table below. For an updated list of known issues, consult our Web site at Synopsis Description Workaround Connections cannot be opened back to the client Windows Vista and Firefox Client firewall does not work on Windows Vista clients (#40657) Virtual IP addresses are not configured on the client. This prevents the connections from being opened from the internal server back to the client. Due to compatibility issues between Windows Vista, Firefox, and the Java plug-in for Firefox in Windows Vista, the Access Client may experience intermittent problems running tunnel sets. When the client firewall is configured for a resource, the Access Client stops working on Windows Vista. Add the following three Outgoing rules to the Client Firewall rules: W.X.Y.Z-W.X.Y.Z 443 TCP Any Accept TCP Any Accept UDP Any Accept Where W.X.Y.Z is the IP address of your Access Point. If using multiple Access Points, add a corresponding rule for each. 9 StoneGate SSL VPN Release Notes for version 1.2.1
