now be optionally disabled ADSL Norway's ISPs details were added to the ADSL wizard Enhanced HTTPS Support To increase security, the following changes were done to the HTTPS web configuration portal (https://my.firewall): - HTTPS web server cookies are now marked as “secure cookies” - HTTPS clients are no longer permitted to select weak 40 and 56 bit ciphers Enhanced L2TP Support The L2TP server has been enhanced to support the following cases: - Windows Vista VPN clients behind a NAT device - Apple iPhone VPN clients Issues resolved HTTP/HTTPS • low severity cross side scripting (XSS) attack potentially possible against the configuration web portal This issue is unlikely to be successfully exploited Resolve issue: Vstream Anti-Virus Resolved issue: in certain cases, VStream Antivirus may block valid connections Firewall • Resolved issue: A memory issue when using DHCP relay ADSL • Resolved issue: ANNEX B DSL modems support for G.DMT standard IP60 • Resolved issue: Nokia IP60 GUI layout appears incorrectly New Features New Security Features Web Rules It is now possible to define Web rules that allow or block access to specific Web sites based on the site’s URL If desired, you can log attempts to access allowed and blocked Web sites In addition, you can exclude specific IP addresses or address ranges from Web rule enforcement Wildcards may be used in web rules to allow partial access to certain web sites This feature does not require subscription to the category-based Web Filtering service and can operate in parallel with the subscription service, if desired When a site is blocked, a configurable message is displayed to the user See “Customizable Web Filtering Page” Time-Based Rules It is now possible to define firewall rules that only take effect during certain hours of the day This feature is supported for locally defined firewall rules, for locally defined antivirus rules, and for firewall rules downloaded from Check Point SmartCenter (rules using time objects) Rule Descriptions A new Description field allows attaching an explanation or remark to each locally defined firewall and antivirus rule This optional field can be used for naming a rule or for explaining why the rule is needed and under what circumstances Reusable Network Service Objects Embedded NGX 7.5 allows defining custom network service objects in the local Web interface and assigning them unique names The network service objects can then be used in firewall rules, antivirus rules, and policy-based routing rules Network service objects consist of an IP protocol and either a TCP/UDP port or a port range It is possible to define several non-consecutive port ranges, by separating them with commas Allow & Forward Rules with Destination IP Address It is now possible to define “Allow & Forward” rules with a specific destination IP address This allows defining NAT forwarding rules that only take effect when accessing a certain IP address Embedded NGX 7.5 allows defining different forwarding rules for each external IP address For example, consider a case in 10 which the gateway has two public IP addresses, 62.98.112.1 and 62.98.112.2, and the network contains two private Web servers, A and B It is now possible, to forward all HTTP traffic with the destination 62.98.112.1 to server A, while mapping all HTTP traffic with the destination 62.98.112.2 to server B Previously, this was only possible using static NAT mappings Advanced users can also use this feature for outgoing traffic, creating "transparent proxy" rules that divert all traffic that is destined for a certain IP address to a different IP address Advanced Address Translation Rule Base Embedded NGX 7.5 allows configuring advanced network address translation (NAT) rules in the local management interface The Address Translation table is divided into Original Packet and Translated Packet sections The Original Packet section specifies the conditions under which the rule is applied, and the Translated Packet section specifies the action taken when the rule is applied You can change the source IP address, the destination IP address, the service, or any combination of the above When translating an IP address range to another IP address range of the same size, static NAT is performed When translating an IP address range to a smaller IP address range, static NAT is performed for all but the last address in the translated range, and hide NAT is used to hide all the remaining addresses 11 in the original range behind the last IP address in the translated range NAT rules can be implicitly defined though a number of methods: by enabling “Hide NAT” on an internal network, by creating an “Allow & Forward” firewall rule, or by configuring static NAT for a network object In addition, NAT rules can be received from the SmartCenter policy editor Implicitly defined NAT rules are displayed in the Address Translation table, but cannot be edited Note: This feature is not available in the ZoneAlarm Secure Wireless Router Z100G New SmartDefense Protection: Checksum Verification When this protection is enabled, SmartDefense will identify and drop IP, TCP, or UDP packets with incorrect checksums New SmartDefense Protection: Urgent Flag Clearing The URG flag is used to indicate that urgent data exists in a TCP stream, and that the data should be delivered with high priority Since handling of the URG flag is inconsistent between different operating systems, allowing the URG flag may enable an attacker to conceal certain attacks 12 By default, SmartDefense automatically clears the URG flag to ensure security To allow the URG flag, in the SmartDefense tree's TCP > Flags node, set the URG Flag field to Allow To prevent the URG flag from being used, set the URG Flag field to Clear New SmartDefense Protection: Sequence Number Verifier When this protection is enabled, Embedded NGX examines each TCP packet's sequence number and checks whether it matches a TCP connection state You can configure how the router handles packets that match a TCP connection in terms of the TCP session but have incorrect sequence numbers Secure HotSpot: Redirect URL The Secure HotSpot feature now allows defining an optional “Redirect URL” When a “Redirect URL” is defined, every user who successfully authenticates to the Secure HotSpot will be automatically redirected to the specified URL For example, the “Redirect URL” can be your company’s Web site or a “Welcome” page This feature is supported in the following platforms: UTM-1 Edge, Safe@Office 500 with Power Pack, Safe@Office 225, and Safe@Office 410/425 Remote Desktop Access Granular Permissions Embedded NGX includes an integrated client for Microsoft Terminal Services, allowing you to enjoy convenient clientless access to your Windows computers from anywhere, via the my.firewall portal System administrators can remotely access the desktop of each of employee's computer, and even redirect printers or ports to a remote computer Starting from Embedded NGX 7.5, granular permissions are now available for Remote Desktop Access, enabling an administrator to limit access to the Remote Desktop Access feature to a limited set of users Non-administrator users which have the “Remote Desktop” permission in their profile can 13 now login to the Embedded NGX web based configuration portal, my.firewall, and gain access to a restricted portal, showing only the “Active Computers” page, and allowing access to the Remote Desktop Access feature Enhanced SIP Support Embedded NGX 7.5 now includes a dedicated ALG (Application Level Gateway) for SIP (Session Initiation Protocol), the popular signaling protocol commonly used for IP telephony (VoIP) This ALG enables easy NAT and Firewall traversal Note: Embedded NGX 7.5 supports SIP over UDP SIP over TCP is currently not supported A SIP Proxy must be used, and the proxy must not reside in the same network as the SIP client Enhanced VPN Topology Display An enhanced topology viewer is now available, for convenient display of the VPN network topology The VPN topology viewer is accessible from the “Active Tunnels” page in the web user interface New Networking Features WAN Load Balancing 14 Embedded NGX 7.5 supports WAN load balancing When WAN load balancing is enabled, two Internet connections can be used in parallel, and the load is automatically distributed between them, based on available bandwidth To prevent disruption of stateful protocols, load balancing is performed on a per source IP address and destination IP address basis, meaning that all traffic from a certain source IP address to a certain destination IP address will be consistently sent to the same Internet connection In the case of a single client communicating with a single server, no throughput benefits will be realized; however, in typical network conditions, where multiple clients or servers are active, bandwidthbased load balancing can balance the use of both Internet connections exceptionally well, effectively doubling the available bandwidth By default, the load distribution is symmetric; however, it is possible to achieve non-symmetric balancing by assigning a different weight to each Internet connection To ensure continuous Internet connectivity, an Internet connection that fails for any reason is automatically excluded from load balancing Note: This feature is supported in the following platforms: UTM-1 Edge X series, UTM-1 Edge W series, Safe@Office 500, Safe@Office 225, and Safe@Office 425 ADSL Configuration Assistant Embedded NGX 7.5 ADSL appliances offer an ADSL configuration assistant To use the ADSL Configuration Assistant, choose your country and ISP, then click OK The appropriate VPI, VCI, and encapsulation type values for your ISP will be inserted automatically You can 15 still change these settings manually at a later time, if needed The ADSL Configuration Assistant appears in both the ADSL Setup Wizard, and in the Internet Setup page For the full list of ISPs supported by the ADSL Configuration Assistant, click here Note: This feature is available in all appliance models with an integrated ADSL modem, including UTM-1 Edge X/W ADSL and Safe@Office 500/500W ADSL ADSL IPoA Support Embedded NGX 7.5 ADSL appliances now support the IPoA (IP over ATM) connectivity protocol, used by certain ADSL service providers Bridged / Unnumbered PPPoA Support Embedded NGX 7.5 ADSL appliances now support bridge mode for PPPoA ADSL internet connections This enables the Embedded NGX ADSL appliance to connect to ISPs who use “Unnumbered” PPPoA mode Routing Table Report Embedded NGX 7.5 includes a new Routing Table report, providing an easy view of the routing table currently in effect The table shows the route's source, destination, gateway IP address, metric, and interface In addition, the table's Origin field displays the route's type: • Connected Routes - Routes to networks directly connected to the appliance • Static Routes - Routes to networks connected through a router • Dynamic Routes - Routes obtained through a dynamic routing protocol The same routing table information can also be obtained through the info routes CLI command 16 Note: This feature is not available in the ZoneAlarm Secure Wireless Router Z100G Connect On Demand in PPPoA, PPPoE, and PPTP Modes "Connect on Demand" is now supported in all PPP modes, including PPPoA, PPPoE, and PPTP In "Connect on Demand" mode, the Internet connection will automatically connect as needed, and disconnect during network idle periods "Connect on Demand" continues to be supported for dialup connections, as in previous Embedded NGX versions Service-Based Policy Routing Embedded NGX 7.5 allows configuring service-based policy routing You can use service-based policy routes to direct all traffic matching a particular protocol and port range to a specific Internet connection For example, you can choose to route all HTTP (TCP Port 80) traffic to the secondary Internet connection, while routing all other traffic to the primary Internet connection To ensure continuous availability, if the secondary Internet connection is unavailable, this rule is automatically disregarded, and the appliance routes the traffic through the route with the next-lowest metric Notes: In a service-based route, the source network and destination network fields cannot be specified Stateful protocols such as passive FTP and SIP will not work as expected with service based routes This feature is not available in the ZoneAlarm Secure Wireless Router Z100G Interface-Based Static Routes Embedded NGX 7.5 allows specifying an Internet connection as a static route's next hop, instead of a specific IP address This feature is useful in cases where the ISP's default gateway IP address is dynamically assigned to the gateway By specifying the Internet connection's name (primary/secondary) in the Next Hop IP field, you can route traffic to a specific Internet connection, without having to statically specify the ISP's default gateway IP address 17 Note: This feature is not available in the ZoneAlarm Secure Wireless Router Z100G Incoming Dialup for Out-of-Band Management Embedded NGX 7.5 supports auto-answering incoming data calls using a dialup modem (PSTN, ISDN or cellular) By dialing into the appliance, an administrator can remotely troubleshoot and reconfigure a device out of band, even if the main Internet connection is inaccessible When incoming dialup is enabled, the gateway automatically answers incoming data calls, and establishes a connection using PPP (Point to Point Protocol) An IP address is assigned to the client from the OfficeMode IP pool To secure the device against unauthorized dialers, the session must be authenticated with a username/password combination belonging to a known user with Administrator credentials To enable Incoming Dialup, check the “Answer Incoming PPP Calls” in the Serial Port setup page, or in the USB modem setup page Enhanced Cellular Modem Support Embedded NGX 7.5 offers a list of predefined cellular modem types, removing the need to provide a custom initialization string in most cases 18 In addition, specific fields are provided for entering the Access Point Name (APN) and Personal Identification Number (PIN) code required by a number of cellular networks Note: USB-based modems (including dialup and cellular modems) are supported in the following appliance models: Safe@Office 500W, Safe@Office 500W ADSL, Safe@Office 425W/425WU, UTM-1 Edge X ADSL, UTM-1 Edge W, and UTM-1 Edge W ADSL A supported external modem with a USB interface is required SNMP Traps A trap is a Simple Network Management Protocol (SNMP) notification sent from one application to another Embedded NGX 7.5 now supports sending the following traps: • Startup / Shutdown • SNMP Authentication Failure • Link Up / Link Down The administrator can choose between SNMPv1, SNMPv2, and SNMP INFORM style traps The trap destination, community, and UDP port are also configurable Syslog Support in ZoneAlarm Z100G ZoneAlarm Secure Wireless Router Z100G now includes support for sending log messages through the Syslog protocol OSPF Simple Authentication Embedded NGX 7.5 supports OSPF “Simple Authentication” mode, in addition to the MD5 authentication mode supported in previous versions New Usability Features New Look & Feel The UTM-1 Edge and Safe@Office appliances' look & feel has been improved with a new, sleek design Enhanced CLI Syntax 19 Command line interface (CLI) commands that are not supported by the current hardware type and license are not displayed as options in the CLI help or as possible command completions Note: The command line interface is not available in the ZoneAlarm Secure Wireless Router Z100G Configurable Serial Console Port Speed When using the appliance’s serial port in “Console” mode, it is now possible to change the baud rate from its default speed (57600 bps) Note: The serial console port speed feature is not applicable to ZoneAlarm Secure Wireless Router Z100G Customizable Web Filtering Page It is now possible to customize the message displayed in the “Access Denied” page This message is used both by the category-based Web Filtering service and by the new Web rules feature If desired, you can use HTML tags in the message In addition, you can force the “Access Denied” page to be displayed using secure HTTP (HTTPS), by selecting the Use HTTPS check box Multiple Concurrent Administrators over HTTP It is now possible for multiple administrators to log on to the my.firewall Web interface concurrently using the HTTP protocol As in previous Embedded NGX versions, multiple administrators can also log on concurrently using HTTPS Enhanced Behavior of VPN LED The VPN LED is now a steady green when there are open VPN tunnels but no VPN activity, and it blinks whenever traffic is sent or received over a VPN tunnel 20 Appendix A: Supported Peripherals For the list of printers known to be supported by the Embedded NGX print server, click here For the list of
