1 SonicOS Enhanced Release Notes SonicWALL, Inc. Software Release: May 14, 2007 CONTENTS Platform Compatibility Enhancements Known Issues Resolved Known Issues in SonicOS Enhanced Resolved Known Issues in SonicOS Enhanced Key Features SonicWALL TZ 190 Hardware Feature Highlights Resetting the SonicWALL TZ 190 Using Safemode Related Technical Documentation PLATFORM COMPATIBILITY SonicOS Enhanced version ( ) is a supported release for the following platform: SonicWALL TZ 190 ENHANCEMENTS Strong SSL and TLS Encryption The internal SonicWALL web-server now only supports SSL version 3.0 and TLS with strong ciphers (128 bits or greater) when negotiating HTTPS management sessions. SSL implementations prior to version 3.0 and weak ciphers (symmetric ciphers less than 128 bits) are not supported. This heightened level of HTTPS security protects against potential SSLv2 roll-back vulnerabilities and ensures compliance with the Payment Card Industry (PCI) and other security and risk-management standards. TIP: By default, Mozilla Firefox 2.0 and Microsoft Internet Explorer 7.0 enable SSL 3.0 and TLS, and disable SSL 2.0. SonicWALL recommends using these most recent web browser releases. If you are using a previous release of these browsers, you should enable SSL 3.0 and TLS and disable SSL 2.0. In Internet Explorer, go to Tools > Internet Options, click on the Advanced tab, and scroll to the bottom of the Settings menu. In Firefox, go to Tools > Options, click on the Advanced tab, and then click on the Encryption tab. Page 1 of 14

2 KNOWN ISSUES The following is a list of known issues in the SonicOS Enhanced release: 45335: Symptom: The Enable Remotely Triggered Dial-Out feature does not work with the Option Globetrotter GT Max card. Condition: Occurs when an incoming call is made to the Option wireless card : Symptom: Management traffic is not allowed through the WAN interface. Condition: Occurs when the WAN Connection Model is configured for WWAN only mode. Workaround: Configure the WAN Connection Model for Ethernet with WWAN Failover and force a failover to the WWAN by unplugging the Ethernet cable : Symptom: Runtime changes to WAN/WWAN probe settings do not always take effect until restart. Condition: Occurs when the default target not reachable and WAN probing fails. The WAN stays in the failover state even after probe monitoring is successful. Workaround: Reboot the SonicWALL security device : Symptom: The WWAN interface fails to re-associate with the wireless network after the WWAN card is reset. Condition: Occurs intermittently on a SonicWALL TZ 190 security appliance using a Novatel S620 or S720 WWAN adapter. RESOLVED KNOWN ISSUES IN SONICOS ENHANCED The following is a list of resolved known issues in the SonicOS Enhanced release: 45514: Symptom: On the Firewall > Services page, the HTTP and HTTPS services display uneditable port ranges of instead of the default ports 80 and 443. Because the HTTP and HTTPS ports are not configurable, it is not possible to block traffic for non-default ports. Condition: Occurs when the SonicWALL TZ 190 security appliance is rebooted : Symptom: Reducing the number of missed probes to redial setting below the defaults can cause a Cingular WWAN card to redial more often than desired. Condition: Occurs when the WWAN Interface Monitoring Setting values are reduced from the default values of: o Check Interface every 5 seconds o Re-establish connection after 6 missed intervals Workaround: Set the WWAN Interface Monitoring Setting to the following: o Check Interface every 6 seconds o Re-establish connection after 10 missed intervals 48244: Symptom: The SonicWALL TZ 190 security appliance spontaneously reboots into SafeMode in certain corner cases. Condition: Occurs when a BSP parameter is set incorrectly on appliances running SonicOS Enhanced Page 2 of 14

3 RESOLVED KNOWN ISSUES IN SONICOS ENHANCED The following is a list of resolved known issues in the SonicOS Enhanced release: 45829: Symptom: The WWAN > Status page displays an incorrect Signal Strength for Sprint cards. For the Novatel cards, the Signal Strength may show Initializing even when it is receiving a signal and in a call. For the Novatel S720 card, the Signal Strength may always show Excellent even if signal is unavailable. Condition: Occurs when the firmware does not get a correct reading from a Sprint card when it queries the signal strength : Symptom: The TZ 190 can occasionally lose its Internet connection when manually changing the WAN Connection Model configuration from Ethernet Only to WWAN Only. This can cause the TZ 190 to restart. Condition: Occurs when the TZ 190 initially uses an Ethernet connection on the WAN port, and then fails over to the WWAN. The user interface might still show Connected for the WWAN status : Symptom: With Policy Based Routing configured, the TZ190 may restart once when you change the WAN Connection Model from WWAN Only to Ethernet Only. Condition: Occurs after the following steps: 1. Policy Based Routing is configured for the Ethernet WAN and OPT interfaces 2. The WAN Connection Model is set to WWAN-only 3. The security appliance is manually rebooted 4. The WAN Connection Model is changed to Ethernet-only 45912: Symptom: After a WAN failover, statistics for Probe Alternate Target always show Target Unavailable. Condition: Occurs when the WAN connection fails and then comes back up while probe monitoring is set to "Probe succeeds when both Main Target and Alternate Target respond" or "Probe succeeds when either Main Target or Alternate Target respond" : Symptom: On the TZ 190, WWAN dialing failure can occur when using a Novatel S620 card. Condition: Occurs when the WWAN is forced to repeatedly terminate and redial (for example, every 60 seconds). This can occur when the Maximum Connection Time is set to one minute : Symptom: For Sprint wireless cards, the Active Band (Service Type) can be incorrectly reported as 'CDMA 1xRTT'. Condition: May occur when Sprint wireless cards are used : Symptom: The TZ 190 should be able to force PAP authentication on a per-profile basis. Condition: Need option on WWAN > Connection Profiles > Add/Edit Dialog > Parameters tab : Symptom: TZ 190 firmware version e does not send heartbeats to GMS. Condition: Occurs when doing HTTPS management, with syslog server port set to : Symptom: Option Globetrotter HSDPA may become unusable. Condition: Occurs when subjected to certain high levels of traffic : Symptom: The user interface (UI) shows incorrect default connection parameters for UAE provider Etisalat. Condition: Occurs when you use the setup wizard or connection profile Add/Edit dialog to create a profile for the UAE provider Etisalat. Page 3 of 14

4 KEY FEATURES The following are the key features supported in SonicOS Enhanced 3.6: Wireless WAN Support SonicOS Enhanced 3.6 for the SonicWALL TZ 190 introduces support for 3G (Third Generation) and other Wireless WAN connections that utilize data connections over cellular networks. The Wireless WAN (WWAN) can be used for: WAN Failover to a connection that is not dependent on wire or cable. Temporary networks where a pre-configured connection may not be available, such as tradeshows and kiosks. Mobile networks, where the TZ 190 is based in a vehicle. Primary WAN connection where wire-based connections are not available and cellular is. Wireless WAN support requires a wireless card and a contract with a wireless network provider. Internet Service Providers (ISPs) and Data Plans You should carefully read and analyze the rate plans provided by various ISPs. Some ISPs fully endorse the use of WWAN cards in firewall/router type deployments, while other vendors specifically discourage such usage. You should read the full terms and conditions of each plan to determine whether your deployment is compatible with the ISP licensing requirements. In North America, Sprint specifically endorses the use of firewall/router deployments and offers true Unlimited Data plans. SonicWALL currently supports both the Novatel S620 and Novatel S720 cards on the Sprint network. Due to the flexibility of the data plans, SonicWALL highly recommends that you consider activating your unit with a Sprint service contract. Other ISPs may or may not endorse the use of WWAN cards in firewall/router deployments and may have more limited data plans that are either capped or charge by the amount of data transmitted. SonicOS Enhanced 3.6 and the TZ 190 support the following wireless network providers (this list is subject to change): Cingular Wireless H3G Sprint PCS Wireless Verizon Wireless Vodafone Telecom Italia Mobile Telefonica T-Mobile TDC Song Orange Page 4 of 14

13 RESETTING THE SONICWALL TZ 190 USING SAFEMODE If you are unable to connect to the SonicWALL security appliance s management interface, you can restart the SonicWALL security appliance in SafeMode. The SafeMode feature allows you to quickly recover from uncertain configuration states with a simplified management interface that includes the same settings available on the System > Settings page. To reset the SonicWALL security appliance, perform the following steps: 1. Connect your management station to a LAN port on the SonicWALL security appliance and configure your management station IP address with an address on the /24 subnet, such as Note: The SonicWALL security appliance can also respond to the last configured LAN IP address in SafeMode. This is useful for remote management recovery or hands off recovery in a datacenter. 2. Use a narrow, straight object, like a straightened paper clip or a toothpick, to press and hold the reset button on the security appliance for five to ten seconds. The reset button is in a small hole next to the connector for the power supply. Reset Button TZ 190 Tip: If this procedure does not work while the power is on, turn the unit off and on while holding the reset button until the Test light starts blinking. The Test light starts blinking when the SonicWALL security appliance has rebooted into SafeMode. Page 13 of 14
