New Software Features and Enhancements Introduced in 6.3.0 The following sections describe the new features introduced in the ScreenOS 6.3.0 release. Copyright © 2015, Juniper Networks, Inc. 9 ScreenOS 6.3.0 Release Notes Authentication • User Authentication—Beginning with ScreenOS 6.3.0, the Juniper Networks security device supports authentication redirection for HTTP traffic that is directed to a nonstandard destination port. Antivirus (AV) and Web Filtering • Sophos Anti-Spam to replace Symantec Anti-Spam—Beginning mid-September 2009, Sophos Anti-Spam service will be made available to the ScreenOS-based products; SSG, and ISG. The Sophos Anti-Spam service will replace the Symantec Anti-Spam. There will be no impact to customers running any version of ScreenOS. No configuration changes are required. The redirection to Sophos servers will be automatic and transparent to the end-user. The security devices will be pointed to the Sophos servers. • Antispam—Beginning with ScreenOS 6.2.0, Antispam enhancement inspects the parameters in the received email header. • Juniper Full Antivirus Database—Beginning with ScreenOS 6.3.0, Kaspersky Lab supports only a single antivirus database known as Juniper Full Antivirus Database. The existing databases such as extended, itw and standard are removed. • Virus Description and Alert Message—If the data sent in FTP or HTTP Traffic contains a virus, the security device replaces the data with a warning message or drops the data. In both cases, a message with a URL link that describes the virus is logged. For SMTP, IMAP and POP3 Traffic, the security device in addition to the above, changes the content type to text/plain, replaces the body of the message with a notice and a URL link that describes the virus, sends it to the appropriate recipient, and notifies the sender. • Web Filtering Whitelists and Blacklists Without a License—Web filtering supports the following features even if the license key is not installed or has expired: • Define Web-filtering profiles and bind them to policies • Retrieve category information for HTTP requests • Define static whitelist and blacklist categories • Check cache for categories NOTE: The device does not support checking the cache for categories if the key is not installed, but it does support this check if the key is expired. • 10 Integrated Web Filtering Based on Group Membership—In the previous release, the URL filter profile was bound to policy. Beginning with ScreenOS 6.3.0 release, the administrator can bind the profile to user group. The Web Filtering (WF) Manager extracts the URL from the request and identifies the username and user group Copyright © 2015, Juniper Networks, Inc. New Features and Enhancements associated with the IP address. If the user belongs to multiple user groups, the WF Manager binds the profile with the user group that has highest priority. Then, the WF Manager identifies the category of the URL and permits or blocks the request accordingly. User groups can be prioritized. • Increased Number of Web-Filtering Profiles on SSG 500–series—For integrated Web filtering, the number of customer-defined profiles for SSG 550 and SSG 520 devices is increased to 300 profiles from 50 (SSG 550) and 25 (SSG 520). Border Gateway Protocol (BGP) • Redistributing Routes in BGP—For each virtual router (VR), BGP can support up to 17000 redistributable routes. The increase in redistributable routes in BGP to 17000 applies to the NetScreen-5000 platforms only. • Display Format of BGP Community Lists—Beginning with ScreenOS 6.3.0, the configuration file displays the BGP community lists in a new AA NN format, where AA identifies autonomous system and NN identifies community. This new format is in compliance with RFC-1997. CLI • x-in-ip set envar x-in-ip x-in-ip In [ISG-1000 and ISG-2000] devices, Protocol 97 forwards traffic through CPU and not hardware, causing high CPU. To allow the unknown protocols like Protocol 97, use the following command: set envar x-in-ip=yes Use unset command to disable envar. Example: The following command allows the unknown protocols like Protocol 97 on the device: set envar x-in-ip=yes reset Device Management • Enabling Syslog on Backup Devices—By default, backup devices in an active/passive NSRP configuration send all syslog messages to the syslog server. This allows an administrator to effectively monitor backup devices. • Simple Network Management Protocol Version 3 (SNMPv3)— ScreenOS 6.3.0 supports SNMPv3 framework. System status data can be collected securely from the device without the data being tampered with and corrupted. The SNMPv3 USM allows ScreenOS to encrypt the confidential information to prevent the contents from being exposed on the network. The SNMPv3 VACM provides a configurable access control model for easy administration. • Interface Administrative Status—ScreenOS 6.3.0 supports a command for setting an interface administrative status to the down state. By default, the administrative Copyright © 2015, Juniper Networks, Inc. 11 ScreenOS 6.3.0 Release Notes status of an interface is set as up. The administrator can disable the administrative status of an interface with the CLI: set interface xx disable • Increased Number of Hosts per SNMP Community—Beginning with the ScreenOS 6.3.0 release, you can configure 64 hosts per SNMP community. In earlier releases of ScreenOS, this value was limited to no more than 40 hosts per SNMP community. • Include Device Serial Number in Log Messages—Beginning with the ScreenOS 6.3.0 release, for system logs, the device serial number is used as a unique device identifier within the logs. • VLAN1 Interface to Support DHCP and AUTO Configuration—Beginning with the ScreenOS 6.3.0 release, the VLAN1 interface of a device in transparent mode supports the DHCP client and AUTO CONFIG features. • Loading Configuration from USB—When the SSG device initializes, and if the administrator has configured envar properly, then ScreenOS can check if the USB device is connected to the port and loads the configuration file usb: auto_config.txt (if the file is stored in the USB device). Dynamic Host Control Protocol (DHCP) • DHCP support—The maximum number of DHCP relay agents supported is enhanced from 3 to 4. Internet Protocol Security (IPsec) 12 • AC VPN Enhancements—ScreenOS 6.3.0 supports dual-hub Auto Connect virtual private network (AC-VPN) where one hub remains active, passing the traffic from one spoke to another spoke until a dynamic VPN tunnel is established. The hub with the highest routing instance priority becomes the active one. The spokes use the VPN monitoring feature to check the status of the hubs. When the hub acting as a primary fails, the dynamic tunnel and its associated NHRP routing instance are removed at both the spokes. Traffic begins to pass through the other hub, which creates a new dynamic tunnel. If the failed hub comes back, the spokes choose this hub again because of the priority setting. However, the traffic continues to flow through the newly created dynamic tunnel until the other fails. • Support for Multiple Proxy IDs Over Route-Based VPN—ScreenOS 6.3.0 supports multiple proxy IDs on a route-based VPN. If multiple tunnels exist between peers, the security device uses proxy IDs to route the traffic through a particular tunnel. For each proxy ID, a specific tunnel and Phase 2 SA are associated. When traffic matching a proxy ID arrives, the security device does a proxy-ID check to route that traffic. If multiple proxy IDs are defined for a route-based VPN, a proxy ID check is always performed, even if it is disabled. In a hub-and-spoke topology, proxy IDs should be defined for both hub-to-spoke and spoke-to-spoke configurations. • DPD Enhancement—ScreenOS 6.3.0 provides a DPD enhancement that allows the dead peer to failover the tunnel to another VPN group member with the second highest weight. It uses the DPD reconnect parameter to renegotiate the tunnel with the dead Copyright © 2015, Juniper Networks, Inc. New Features and Enhancements peer at specific intervals. If the tunnel is successfully renegotiated, the tunnel fails back to the first member. • Elliptical Curve Diffie-Hellman Key Arrangement—ScreenOS 6.3.0 supports elliptical curve Diffie-Hellman (ECDH) groups 19 and 20 for Internet Key Exchange version 1 (IKEv1) key exchange. ECDH uses elliptical curve cryptography to generate public-private key pair. The module sizes of DH groups 19 and 20 are 256 bits and 384 bits ECDH prime curves, respectively. • Support Authentication Header Transport Mode—[ISG 1000/2000, NS 5200/5400 M2/SPM2 , NS 5200/5400 M3/SPM3] ScreenOS 6.3.0 supports authentication header (AH) transport mode on high-end systems for IPv4 packets only. This feature does not work if IPv6 is enabled in the system environment. • IKEv2 Configuration Payload (CP) and Dial-up Support—Support for IKEv2 configuration payload (CP) for dynamic end points and IKEv2 dial-up group user VPN is available in this release. For details on the implementation, refer to the Concepts & Examples ScreenOS 6.3.0 Reference Guide. Internet Protocol Version 6 (IPv6) • Support OSPFv3 for IPv6 —Beginning ScreenOS 6.3.0, Juniper Networks security device supports OSPFv3 for IPv6. Most configuration and operational commands function essentially the same as in OSPFv2. OSPFv3 does not support the following features: • NBMA link and neighbor authentication • Demand Circuit and NSSA • Multiple instances per link. OSPFv3 is supported across all platforms. However, advanced mode license is required to run it on the following devices: • ISG1000 • ISG1000 with SM • ISG2000 • ISG2000 with SM • Command to Inhibit AAAA Requests over IPv4—ScreenOS 6.3.0 provides an option to enable or disable the Network Address Translation-Port Translation Domain Name System Application Layer Gateway (NAT-PT DNS ALG) to modify DNS requests received from the IPv6 domain. Besides translating the addresses for transmitted DNS requests, the NAT-PT DNS ALG also modifies the DNS request before forwarding it to another domain that has only IPv4 addresses. By default, this option is disabled. • IPv6 Prefix and DNS Information Update—ScreenOS 6.3.0 supports dynamic IPv6 prefix and DNS information update from the upstream DHCPv6 server. A CPE router acting as a DHCPv6 and PPPoE client negotiates IPv6 prefixes and DNS information for the downstream DHCPv6 server on the other interface of the same CPE router. If the connection between the CPE router and the upstream DHCPv6 server is Copyright © 2015, Juniper Networks, Inc. 13 ScreenOS 6.3.0 Release Notes disconnected and then re-established, the CPE router updates the newly learned IPv6 prefix and DNS information dynamically on the downstream DHCPv6 server without waiting for the delegated prefix to expire. • SIBR IPv6 Support—Beginning with ScreenOS 6.3.0r13, the Source Interface-Based Routing (SIBR) feature supports IPv6 SIBR tables. When SIBR is enabled in a virtual router (VR), the security device performs route lookup in an SIBR routing table. The configuration of this feature remains the same, except for the fact that the interface gateway cannot be used as a next-hop if the IPv6 gateway parameter is not specified. The CLI command is updated as:set vrouterroute source in-interface interface gateway • Client-to-Site IPv6 VPN Support—Beginning with ScreenOS 6.3.0r13, configuring IPv6 addresses from a server to a client is now supported with IPv6 IP pools. A new command has been introduced:set ippool [ippool name] . ISG-IDP Diagnostic Improvements • IPv6 Full Support on ISG-IDP—Beginning with ScreenOS 6.3.0, ISG Security Module provides IPv6 support for the following features: packet capture and packet logs for IPV6 traffic; configure header match information for IPv6 traffic and ICMPv6 messages; IPv6 traceroute anomaly; IPv6 log messages in the NSM log viewer. • ISG-IDP Means to Identify the Secure Module (SM) Used by a Session—Beginning with ScreenOS 6.3.0, users can identify which SM card and CPU a session is using. It is possible to filter the session table output with the CLI command get session sm-slot slot-id sm-cpu cpu-no. • Command for Displaying CPU Usage on SM—Beginning with ScreenOS 6.3.0, users can enable the security device to calculate the CPU usage of the ISG Security Module for the last 60 seconds, last 60 minutes, and last 24 hours by using the sc_enable_cpu_usage parameter. • Transfer Core Dump to the Management Module Flash or Compact Flash—Beginning with ScreenOS 6.3.0, users can transfer the core dump files from the RAM disk of the ISG Security Module to the flash memory of the management module using the CLI command set sm-ctx coresave. • SNMP Trap and Event Log Entries for ISG with IDP—From ScreenOS 6.3.0, ISG Security Module supports generating log messages and SNMP Traps when CPU usage, memory usage, and session count per IDP security module exceeds the user-defined threshold. The device also generates messages when it detects an IDP security module failure. NOTE: The user-defined threshold value is not stored in NSM. The value is reset to the default once the system reboots. • 14 Inspection of Multicast traffic by IDP Security Module—Beginning with ScreenOS 6.3.0, users can enable ISG Security Module to inspect multicast traffic by using the CLI command set flow multicast idp. Copyright © 2015, Juniper Networks, Inc. New Features and Enhancements NOTE: For multicast traffic inspection, all outgoing interfaces should belong to the same zone. • UAC Integration with Role-Based IDP Policy—From ScreenOS 6.3.0, ISG Security Module can support role-based IDP policy. Administrators can configure the security device to inspect traffic using either user roles or source IPs. When user-role-based IDP inspection is selected, the security device starts checking user-role-based policies first; if a match is not found, only then the security device searches for IP-based rules. This feature requires UAC deployment and role information is provided by Infranet Controller. Network Address Translation (NAT) • Enhancement to IKE and ESP Passthrough Traffic—Beginning with ScreenOS 6.3.0, Network Address Translation (NAT) supports both NAT-Traversal and Non-NAT-Traversal IKE and IPsec passthrough traffic. The Application Layer Gateway (ALG) is enabled to support interface NAT and IKE DIP pool NAT. • Support for More Than 62946 Sessions per IP in a DIP Pool —When the security device performs NAT-src with a DIP pool containing an IP address range with PAT enabled, each DIP:DPort pair can only be assigned to one session. Beginning with ScreenOS 6.3.0, you can enable DIP to support multiple sessions per DIP:DPort. The DIP pool supports multiple session per DIP:DPort only if two packets have different destination IP addresses. After configuring the DIP pool scale size, every IP address contains multiple port pools that consist of all available ports for an IP address. Every IP can support up to scale-size* 62463 sessions. The maximum scale size for an interface cannot exceed the DIP scale size value specified in the vsys profile. • TCP Session Close Notification—ScreenOS sends a TCP session close notification ACK message to both the client and the server when a session is being closed. To enable a policy to send TCP session close notification, complete the following prerequisites: • • You must enable TCP SYN checking and TCP reset options in both the client and the server zones. • You must enable TCP sequence check only for ISG 1000/2000 and NS 5200/5400. Creating a Session Cache to Accelerate HTTP Traffic—Beginning with ScreenOS 6.3.0, you can create a session cache for HTTP-based protocols to minimize CPU utilization and to enhance performance. A session cache is a special structure that caches all the reusable information of both software and hardware sessions created by the first connection of an HTTP session bundle. A session cache supports other traffic but does not ensure performance enhancement. You cannot create a session cache for the following conditions: • When the session is synched from another security device. Copyright © 2015, Juniper Networks, Inc. 15 ScreenOS 6.3.0 Release Notes • • When the session is created by an Application Layer Gateway (ALG). Importing Traffic to the Correct VSI by Proxy ARP—The administrator can enable importation of traffic to the correct VSI by setting the proxy ARP entry. Upon adding a proxy ARP entry on an interface, ScreenOS imports the traffic that is destined to the IP range using this interface. You can use the CLI command proxy-arp-entry or WebUI Network > Interface > Edit> Proxy ARP Entries to set the proxy ARP entry. • NAT-Dst Port Shift using VIP—Using the port-range VIP entry, a range of ports can be mapped between Virtual IP and Real Server IP. NetScreen Redundancy Protocol (NSRP) • Add More Detail to the Output of get nsrp—The output of the get nsrp vsd-group command includes a new column; the uptime column for VSD group or myself uptime column for current security device denotes the duration in the primary or backup state. Other • Hot Patch Management—Beginning with ScreenOS 6.3.0, the hot patch enables injecting the customer service patch into the running image without rebooting the security device. The hot patch as debug patch provides for easier debugging. The ScreenOS hot patch management component runs on the security device and performs the following functions: 16 • Loads the hot patch file from TFTP to flash memory • Removes the hot patch file from flash memory • Maintains the patch finite state machine (FSM) • Cache Recently Used Route and ARP Entries—Beginning with ScreenOS 6.3.0, Juniper Networks security device allows the user to cache recently used route and ARP entries for destination routes by using the set flow route-cache command. This feature does not work if ECMP is enabled. • Ability to Add exec and save Commands to Scripting Tool—Beginning with ScreenOS 6.3.0 release, the ScreenOS scripting tool supports the exec and save commands. These commands are visible in the script context record. The parser identifies these commands in the script record context and saves them into the script. This enhancement enables the user to execute commands that facilitate troubleshooting. • Timeout for Track IP—Beginning with ScreenOS 6.3.0, the user can set the maximum timeout value for track IP. • Boot with Default Gateway IP—The new ScreenOS boot loader allows you to define a default gateway IP, then user can download image from a remote TFTP server. • Identifying Gigabit Interface—Beginning with ScreenOS 6.3.0, users can identify the type of gigabit interface using the CLI command get interface interface-name.

New Features and Enhancements • Boot Loader for SSG and Boot ROM Version for ISG or NetScreen–5000 series Displayed in CLI—Beginning with ScreenOS 6.3.0, you can view the boot loader for an SSG device and boot ROM version for ISG or NetScreen–5000 device using the get system command. Example 1: ssg20-> get system BOOT Loader Version: 1.3.2 Example 2: nsisg2000-> get system BOOT ROM Version: 1.1.0 • • WELF Log Format Enhancement—Beginning with ScreenOS 6.3.0, enhancements have been made to the event log, traffic log and IDP log formats to follow the WELF log regulation. If backup for the logs is enabled, logs can be sent to a maximum of four Webtrends servers. TCP or UDP transport protocol can be used for communication. IP connections can be manually reset. The following log types must be sent along with the appropriate heading prefix: • Configuration log [Config Change] • URL Filter Detection [URL filtering] • AntiVirus Detection [AntiVirus] • Antispam Detection [AntiSpam] • IPS/DI Detection [IPS/DI] • Screen Attack [Attack] SCTP Protocol Filtering—Beginning with ScreenOS 6.3.0, the existing Stream Control Transmission Protocol (SCTP) stateful firewall supports protocol filtering. You can configure the security device to permit or deny traffic based on the SCTP Payload Protocol and M3UA Service Indicator. The Payload Protocol identifies the type of data being carried out by the SCTP data chunk, the M3UA Service Indicator identifies the type of data being carried out by the M3UA data message. Based on the Payload Protocol, you can create an SCTP profile and bind it to a policy. NOTE: ScreenOS supports SCTP protocol filtering on NetScreen-5000 and ISG series devices only. • Converting join-group igmp Commands to exec join-group—Beginning with ScreenOS 6.3.0, the exec join-group and exec leave-group commands replace the set igmp join-group and unset igmp join-group commands. The exec join-group command replaces the set join-group command. The exec leave-group command replaces the unset join-group command. There is no impact on the functionality of the commands. The set and unset commands are deprecated. • Boot Loader for SSG-140—A new boot loader version Loadssg140v326.d has been released for SSG-140 platform. For more information, see the JTAC knowledge base number KB 23407 located at http://kb.juniper.net/KB23407 Copyright © 2015, Juniper Networks, Inc. 17 ScreenOS 6.3.0 Release Notes Policies • Policy Installation Enhancement —Beginning with ScreenOS 6.3.0, the policy installation process has been enhanced. The new process provides the following advantages: • Avoids frequent policy re-installation caused by dynamic DNS address changes. • Eliminates traffic drops while installing the policy. • Allows the user to configure the hold-interval option of policy installation using the following CLI command: set policy install hold-interval seconds The default value is 5 seconds. The minimum is 0 and the maximum is 10. This command specifies the maximum time interval between when policy configuration occurs and actual policy installation begins. When the user creates a new policy or modifies an existing policy, the policy installation is delayed by up to the value of hold-interval value specified. This allows the system to more efficiently process the session table by handling several updates at once or by reducing the thrashing caused by extremely rapid updates. unset policy install hold-interval The unset command resets the default value of hold-interval. Example: To configure hold-interval option to 2 seconds: set policy install hold-interval 2 • DSCP Marking for Self-Initiated Traffic—Beginning in ScreenOS 6.3.0r12, you can configure IKE packets with DSCP values for self-initiated packets. During IKE module process negotiation, the configured IKE packets marked with the values can be used. To mark the IKE packets with the specified value, enable the service using the command set ip service ike dscp . • DSCP Marking Based on Policy Configuration—In ScreenOS 6.3.0r12, when a session matches a policy with DSCP enabled, the bidirectional traffic performs the DSCP marking. The DSCP feature is now enhanced to prevent DSCP re-marking packets that already have a DSCP value. This feature enables a DSCP group to have more than one DSCP value for a packet. The DSCP marking for each packet is checked to determine whether the DSCP value belongs to a DSCP group before the packet does the DSCP marking. If the DSCP value does not belong to a DSCP group, the device retains the packet's DSCP value. Low-End Platforms—For CPU-based platforms, all packets in the first path or fast path are checked for DSCP value and DSCP marking based on policy configuration. The configuration is effective in all conditions irrespective of whether the first packet matches the policy configuration or not. High-End Platforms—For high-end platforms, the DSCP marking for fast path is processed by the ASIC according to the session installed by the first path. Only the first 18 Copyright © 2015, Juniper Networks, Inc. New Features and Enhancements path is checked for the DSCP value to determine the DSCP marking based on policy configuration. If the first packet arrives with an existing DSCP value and if the DSCP value does not belong to the DSCP group in the policy configuration, then the session will not perform DSCP marking for that packet. Subsequent packets in the session will also not have the DSCP marking done even if the DSCP value matches the DSCP group in the policy configuration. NOTE: If the policy has been configured as no-hw-sess in high-end platforms, then the implementation is same as in low-end platforms, as all the packets are processed by the CPU. The DSCP group is used to classify traffic within the device and to classify a number of DCSP values having the same behavior as the configured DSCP group. The DSCP group allows you : • To create a DSCP group and to define the DSCP group type. The maximum number of DSCP groups allowed per VSYS is 64. The DSCP group types are: • Include—Specifies adding or including the DSCP values to the configured DSCP group . By default, the DSCP value for a group is zero. set dscp-group name include • Exclude—Specifies to removing or excluding the DSCP values from the configured DSCP group. By default, the group contains 64 DSCP values. set dscp-group name exclude • To configure a DSCP value for a policy. If a DSCP value is not configured for any policy, then you can insert a DSCP value into a DSCP group, or you can delete a DSCP value from a DSCP group. set dscp-group dscp-value - • To display the DSCP group information. get dscp-group • To bind a DSCP group to a policy for low-end platforms: Set policy from to traffic dscp enable group-dscp Set policy from to traffic dscp enable group-dscp Set policy from to traffic dscp enable value group-dscp Set policy from to traffic dscp enable group-dscp • To bind a DSCP group to a policy for high-end platforms: Copyright © 2015, Juniper Networks, Inc. 19 ScreenOS 6.3.0 Release Notes Set policy from to traffic priority dscp value group-dscp Set policy from to traffic dscp value group-dscp Set policy from to traffic priority group-dscp Routing • IRDP Support for All Platforms—Beginning with ScreenOS 6.3.0 release, ICMP Router Discover Protocol (IRDP) support is available on all platforms; however, IRDP support is available only on an Ethernet interface with an IP address. • DSCP Marking for Self-Initiated Traffic—The administrator can configure the DSCP value for traffic initiated by the security device. The DSCP value can be configured for 11 services: BGP, OSPF, RIP, RIPNG, TELNET, SSH, WEB, TFTP, SNMP, SYSLOG, and WEBTRENDS. You can use both the CLI and the WebUI to configure DSCP marking. • QoS Classification Based on Incoming Markings—In ScreenOS 6.3.0, traffic-shaping policies are enhanced to support quality of service (QoS) based on the IP precedence and Differentiated Services code point (DSCP) marking of incoming packets. The QoS classification feature for incoming traffic works only if the traffic-shaping mode is set to Auto or On. • Adding Routes to BGP—In ScreenOS 6.3.0r11, the Border Gateway Protocol (BGP) conditional advertisement feature supports route advertisement using different address family checks. By default, a BGP advertises the best routes in its routing table to its peers. You can use the BGP conditional advertisement feature by using the check option in set vr protocol bgp command to configure conditional advertisement of BGP routes to a peer or a peer group in a different address family. BGP conditional advertisement is supported in IPv4 and IPv6 address families. • To configure and to advertise one IPv4 network route to peer and check the reachability of one IPv4 subnet or IPv6 subnet: set vr vr-1 protocol bgp ipv4 network check • To configure and to advertise one IPv6 network route to peer and check the reachability of one IPv4 subnet or IPv6 subnet: set vr vr-1 protocol bgp ipv6 network check The conditional advertisement feature has been enhanced to include the following new configuration option and parameters to check the subnet of different address family: • ipv4_addr/mask — The IP address and subnet mask of the network. The subnet mask value indicates which bits of the address are significant. The mask does not have to be the same as the subnet mask used in the network. For example, 10.0.0.0/8 is a 20 Copyright © 2015, Juniper Networks, Inc. New Features and Enhancements valid network to be advertised by BGP. When the check option is used, ip4_addr1/mask1 can be a MIP address range. • ipv6_addr/prefix_length — The IP address and prefix length of the network. The address is specified in hexadecimal format, using 16-bit values between colons. The prefix length is a decimal value that indicates how many of the high-order contiguous bits of the address comprise the prefix (the network portion of the address). • check— Directs the device to check network reachability before advertising BGP peers. Security • Denial of Service Attack Defenses—ScreenOS 6.3.0 supports the feature of strict TCP-SYN-check wherein a strict syn check is applied to all the packets in a TCP three-way-handshake before the three-way handshake completes. Users can enable this feature by using the set flow tcp-syn-check strict command. • Verification of IP address in ASIC Whitelist—Beginning with ScreenOS 6.3.0, users can verify if a specific IP-address is in the ASIC whitelist by using the get asic ppu whitelist ip-address command. • Support for SecureID Server Cluster—RSA supports a primary server and up to 10 replica servers to process authentication requests. At least one of primary or slave servers must be configured with static IP. RSA SecureID Server Cluster supports the name locking, load balancing, and failover functions. Virtual Private Network (VPN) • Enhancement to VPN support in VSYS— The system can only support up to 16K static VPN tunnels in a VSYS. An enhancement was made to enlarge per-VSYS static tunnel capacity to the system max (25K) by preempting VPN group tunnels via environment variable "no-vpn-grp=yes". • Automatically Configuring a Local IPv6 Address for an IPv6 IKE Gateway— In ScreenOS 6.3.0r11, you can automatically configure a local address for IPv6 IKE gateway. In order to configure an IPv6 IPsec tunnel, you must define the local IPv6 address in the IKE tunnel configuration. When you are configuring large number of devices, defining a local IPv6 address can be difficult. This enhancement enables you to automatically configure a local IPv6 address through DHCPv6 or IPv6 Stateless Address Auto Configuration (SLAAC) into the IKE tunnel configuration. To automatically configure a local address for an IPv6 IKE gateway, set the IPv6 address 0::0 as the local address in the following command: • For IKEv1 set ike gateway address aggressive outgoing-interface local-address 0::0 preshare sec-level standard Copyright © 2015, Juniper Networks, Inc. 21 ScreenOS 6.3.0 Release Notes Changes to Default Behavior This section lists changes to default behavior in ScreenOS 6.3.0 from earlier ScreenOS firmware releases. Changes to Default Behavior Introduced in 6.3.0 • BGP Configuration — After you upgrade from ScreenOS 6.1 to ScreenOS 6.3, only the connected route will be displayed in the routing table. However, the BGP route export will fail, because the firewall is not configured to the connected routes. To force the route export: set vrouter "trust-vr" set protocol bgp [...] set ipv4 network no-check [...] • New Image Key — ScreenOS firmware versions are now signed with a new image key. Before you can upgrade any ScreenOS image, that has a date of August 13, 2014, or later, you will need to either install the new image key or delete the previous image key. NOTE: As on August 13, 2014, the previous versions of ScreenOS firmwares that were signed with the old image key are removed from the Juniper Networks software download site and reposted after signing with the new image key. For more information, see the JTAC knowledge base numbers TSB16495 and TSB16496 located at https://kb.juniper.net/TSB16495 and https://kb.juniper.net/TSB16496 respectively. 22 Copyright © 2015, Juniper Networks, Inc. Changes to Default Behavior Changes to Default Behavior Introduced in 6.3.0r17 • SNMP Configuration — An “ipaddr has been configured in v1/v2 mode." error was displayed when an SNMPv3 was being configured after SNMPv2 was configured. An “ipaddr has been configured in v3 mode." error was displayed when an SNMPv2 was being configured after SNMPv3 was configured. Changes to Default Behavior Introduced in 6.3.0r13 • NSRP Configuration—The backup interface status (ifOperStatus) displays the state as testing when the physical interface status is UP and as down when the physical interface status is DOWN in an NSRP passive cluster member. Changes to Default Behavior Introduced in 6.3.0r11 • Public Key Infrastructure— A new command is introduced to support manual certificate renewal process by using the same distinguished name without modifying the configuration but by updating the existing certificate in use by removing it. set pki x509 manual-renew To work on this feature, perform the following: • • Generate a key-pair: If the key-pair with the DN is supported in PKI-store, then add a pad to PKI-store using CN=NSMANAULRENEW command to generate a new key-pair. As a result, there are two key-pairs in PKI-store. • Generate a PKI request: If there is a pad CN=NSMANAULRENEW already available in the DN for the key-pair, then remove the pad to generate PKI request. This is to ensure that the new certificate will have the same DN as the old certificate. • Load the certificate: The new certificate with the same DN replaces the old certificate. Recording event log messages in the right VSYS — In a multiple VSYS configuration on the firewall, an event that occurred in a specific custom VSYS-A was incorrectly recorded as an event log message in the root VSYS or in a different custom VSYS-B. This behavior is corrected and fixed. As per the behavior change we now log the event log messages under the right VSYS specified for and will avoid logging incorrect event log messages in different VSYS. Changes to Default Behavior Introduced in 6.3.0r8 • IGMP packets compatibility —A command was introduced to permit IGMP packets with TTL greater than one and to provide compatibility with other interoperability devices: set interface protocol igmp no-check-ttl • Firewall can block packets with a Routing header—Firewall has the ability to block packets with a routing header type 0. To avoid blocking all the routing headers, the firewall supports the routing header type filters using the following command: set service < name>protocol routing-ext-hdr type Copyright © 2015, Juniper Networks, Inc. 23 ScreenOS 6.3.0 Release Notes Changes to Default Behavior Introduced in 6.3.0r7 • HMAC SHA-256 RFC 4868 compliance—The previous implementation of HMAC SHA-256, incorrectly truncated the message digest at 96 bits. It now uses 128 bits, in accordance with RFC 4868. Changes to Default Behavior Introduced in 6.3.0r5 • IPv6 packet extension header—To filter or deny the extension header with user-defined service, define the src-port and dst-port as wildcard 0-65535. Changes to Default Behavior Introduced in 6.3.0r4 • NSRP Configuration—NSRP configuration is out of synchronization due to set tftp source-interface command. Changes to Default Behavior Introduced in 6.3.0r3 • Increase in the capacity of number of service objects and address groups—For ISG Series, the capacity of number of service objects and address groups is increased to 4096. For NS 5000, only the capacity of number of service objects is increased to 4096. • Maximum timeout value of ipsec-nat alg—The maximum value of ipsec-nat alg timeout has been changed from 180 to 3600 seconds. • VPN tunnel capacity for advanced license key—On SSG550, the VPN tunnel capacity has been changed from 1000 to 2048 for advanced license key. • Unexpected Low VPN Throughput—When VPN monitor is configured for VPNs on NetScreen-5200 or NetScreen-5400, the device can define sub-optimal ASIC mapping for processing VPN traffic in the hardware which causes unexpected low VPN throughput. A new command set flow ipsec-distr-asic is introduced to include the enhancement that VPN encryption will be distributed into different chips based on the tunnel's SA index per round robin. By default, it is disabled. This is applicable for NetScreen-5000 series only. For NetScreen-5000 series with VPN on IPv6 environment, enabling this command is not recommended as it would yield less than optimal performance. Changes to Default Behavior Introduced in 6.3.0r1 • The set igmp join-group and unset igmp join-group commands for the interface are deprecated. If you execute the set/unset igmp join-group commands, the following warning appears: WARNING: This command is a deprecated command and cannot be saved to configuration. Please use the following new preferred syntax: exec igmp interface if_name join-group group_addr [{ include | exclude| to_include |to_exclude} sources_ip ] • 24 The CLI command set interface interface nameproxy-arp-entry ip_min ip_max takes precedence over the existing set arp nat-dst command. This means that when the Copyright © 2015, Juniper Networks, Inc. Network and Security Manager (NSM) Compatibility proxy ARP entry is defined and matched, then the system does not respond to the ARP request via the physical interface. Because the set interface interface nameproxy-arp-entry ip_min ip_max command allows the customer to have better control of the device, the command set arp nat-dst is not recommended. • The SNMP changes might affect the management software as follows: • Logical interfaces are added to the interface table. • Several new SNMP traps are introduced in the ScreenOS 6.3.0. For details on the new SNMP traps, see the change history of published ScreenOS 6.3.0 MIB NS-TRAPS.mib. You can consider modifications as required. Network and Security Manager (NSM) Compatibility This section provides information about updates required to complementary Juniper Networks products to ensure their compatibility with ScreenOS 6.3.0.

Virtual Private Network (VPN) 76 • 442719—Unable to configure a C Class Broadcast IP address for the IKE Gateway address. • 448720—Unable to remove User Group that was previously bound to a VPN, even after that VPN has been removed. • 452080—The TCP 3-way handshake failed because of an error in the setup of IPsec VPN. • 455520—Tunnel interface was not created when route based VPN configuration was pushed from the NSM. • 459053—A logically down interface might still respond to VPN monitor packets sent by a VPN peer device, and hence not allowing the VPN state to go down. • 459239—Xauth information was erroneously removed when initial-notify was received. • 474622—[IKEv2] Tunnel IP address did not get released when Dial-Up IKE v2 SA was terminated. • 474923—[IKEv2] Rekey is unsuccessful when using Dial-Up VPN. Copyright © 2015, Juniper Networks, Inc. Addressed Issues WebUI • 455462—Using the WebUI, when an aggregate BGP route was added, a new option summary-only was added that was not specified in the WebUI. • 459894—Unable to remove the address book object "DMZ Any" after it was configured. • 463137—IRDP cannot be enabled on interface e0/0 using the WebUI. • 465697—In certain conditions, the WebUI management causes the system to reset because of incorrect parameter value. • 468211—In the WebUI, the IPv6 route entry did not accept uppercase characters for an IPv6 address. • 469439—VPN monitor configuration might rollback to default after editing vpn entry from the WebUI. Addressed Issues from ScreenOS 6.3.0 The following operational issues were resolved in this release: Administration • 309759—Reloading configurations while the device is experiencing heavy traffic might cause the device to fail. • 388700—It is currently possible to configure a VIP from a subnet other than the unnumbered tunnel interface IP. However, this is not a supported configuration; admins should not be allowed to configure a VIP from a subnet other than the unnumbered tunnel interface IP. • 414839—The policy logs in syslog did not show the correct data sent or received for FTP. • 416873—After a reboot, some event log entries were not recorded in the syslog file, when the syslog was configured using UDP. • 429883—The MSS-based sockets were changed on the new accepted socket. • 432014—The authorized user with read and write privileges is able to issue the set admin password command because of which some user privileges are lost. Application Layer Gateway (ALG) • 446420—The Microsoft windows management interface (WMI) control service fails in some scenario. Antivirus (AV) • 299960—Using the new Kaspersky Labs antivirus scan engine, the antivirus database takes a relatively long time (1 to 5 minutes) to load from a flash disk to system memory. While the database is loading, CPU usage might go extremely high and device performance might drop. Copyright © 2015, Juniper Networks, Inc. 77 ScreenOS 6.3.0 Release Notes • 388885—The extended antivirus (AV) pattern file was too large for the flash memory devices that support this function. However, the standard antivirus pattern file worked as expected. ISG 1000/2000 and NetScreen 5000-series devices do not support the extended AV pattern file setting. Authentication • 429374—Re-authentication for dot1x was not handled correctly. Command Line Interface (CLI) • 435979—[SSG 500] The output of the get chassis command does not include PIM name. • 392417—The set tag command under vsys was not configured correctly. Deep Inspection (DI) • 410393—When updating offline from the Local Server, the automatic DI signature update fails. • 426280—The attack db rollback command did not work on some platforms. For the other platforms, the result of the command was logged as either successful or failed in event log. Domain Name System (DNS) • 439044—If syslog server is referenced using DNS hostname, syslog messages are still sent to the original IP address even after the IP address of the hostname is changed. Flow • 235781—Using transparent mode, under high traffic conditions, sometimes a small number of sessions cannot be cleared. The sessions appear to be "time 0" but continue to remain in the session table. Running set sat session-clean clears these sessions from the table after one round of session cleaning. • 239631—If you configure the initial session timeout below the valid range (20–300 seconds), the system interprets these values as minutes instead of seconds. General Packet Radio Service (GPRS) 78 • 422979—When GTP inspection was enabled, ICMP Destination Unreachable packets of the GTP session were dropped. • 426075—When GTP inspection was enabled, occasionally a DeletePdpResponse or EchoResponse dropped and the message non-existent gsn appeared in the log. Copyright © 2015, Juniper Networks, Inc. Addressed Issues High Availability and NetScreen Redundancy Protocol (HA and NSRP) • 235303—Delay in the peripheral devices updating the forwarding table when a failover occurs in an NSRP cluster in transparent mode. When the devices have no gratuitous ARP mechanism as in NAT or Route mode, peripheral devices update the forwarding table only when the active physical interface is restarted. The update happens after five seconds by default. • 236275—In transparent mode, if the VSD group is not bound to a VLAN group, the security device incorrectly reports the VSD as being in Active-Passive mode. • 236634—In an Active-Passive configuration, if the active security device handles a large number of FTP connections, the CPU utilization of the backup device remains high even when the rate of the FTP connections per second on the backup is low. • 253467—If a device's SIP traffic is very heavy in an NSRP deployment, although the master box works well, there are delays when resources on the backup box are removed. Operational impact on the cluster is minimal, and the backup box recovers automatically. • 303714—For NSRP cluster deployments, when upgrading from ScreenOS 5.4 (or any earlier release), the following ALGs do not sync correctly until both devices in the pair are upgraded: SIP, SCCP, MGCP, RTSP, SQL, PPTP, P2P, AppleiChat, and H.323. • 422747—In the Active/Active mode, FIN packet in the NSRP data path is not processed correctly when SYN-CHECK is enabled. • 424242—When performing an NSRP failover, the route pointed to a different tunnel interface. However, the synchronized session continued to point to the old SA tunnel. • 437661—The RIP and OSPF MD5 authentication results in the NSRP configuration are not in synchronization. • 438794—Backup NSRP firewall lost synchronized OSPF routes. Intrusion Detection and Prevention (IDP) • 305128—If only a destination port (dst-port) is specified in IDP flow filter, the filter does not capture traffic in both directions. • 305295—If an IDP rule is configured with the attack value NONE, then diffserv does not work. Also, when the IDP rule attack value is NONE, if a TCP packet that matches the drop packet action passes through the device, IDP is unable to escalate the response and drop the connection. • 410393—When updating offline from the Local Server, the automatic DI signature update fails. • 426280—The attack db rollback command did not work on some platforms. For the other platforms, the result of the command was logged as either successful or failed in event log. Copyright © 2015, Juniper Networks, Inc. 79 ScreenOS 6.3.0 Release Notes Internet Protocol Version 6 (IPv6) • 227934—SSG platforms incorrectly process the ICMPv6 error packet that they receive in response to a non-first fragment packet that exceeds the outgoing interface MTU. • 236085—In transparent mode, you cannot manage a zone that is on a vsys using the zone nsrp manage CLI command, because it is a global setting based on vlan1 interface. In root mode, you can manage only the related vsys. • 236087—On SSG 320/350 devices, a 4-byte PVE tag is used to identify which interface the packet came from, limiting the maximum supported packet length to 1514 bytes. • 236549—When deployed in transparent mode, some high-end platforms such as ISG 1000-IDP do not support more than 20 reassembled segments. If you try to ping another device with data that requires more than 20 reassembled segments (for example, 30,000 bytes), the ping request fails. • 239285—ScreenOS does not verify the IP address that you enter when you configure the security device. • 239598—On some high-end platforms, after you have enabled IPv6, the CLI incorrectly allows you to enable parameters such as DSCP marking, IDP, and NSRP Data Forwarding that are not supported in IPv6 mode. • 267239—When modifying an IPv6 or a wildcard policy through the WebUI, all existing sessions for the policy are removed. However, existing sessions are not removed if you only modify some minor features—such as session-limit or alarm-without-drop—of an ordinary IPv4 policy through the WebUI. Management 80 • 218168—The incorrect range in integrated URL filtering SC-CPA cache is causing NSM validation error. • 272925—When the console timeout is set to 0, telnet client applications have no way to determine when a session has timed out. If the telnet client has not sent data for a significant length of time and the session should timeout, the TCP socket for the telnet session might not be correctly released. • 292490—NSM update fails when configuring IKEv2 soft lifetime buffer. • 438684—The set flow mac-cache-mgt command is not working for the management of the backup firewall using the master firewall. Copyright © 2015, Juniper Networks, Inc. Addressed Issues Network Address Translation (NAT) • 403509—DIP leaks when a loopback interface for cross-Vsys is used simultaneously with a loopback group in the destination vsys for outgoing DIP NAT. Other • 255774—The debug command unset console dbuf might make the box unstable, especially under heavy traffic. Administrators are advised to use care when running this command. • 258931—Due to a memory limitation, NS 5000 devices are currently unable to support 500 vsys when an advanced license key—such as for virtual router or Layer 2 Active-Active support—is part of the deployment. • 263480—When a small second packet follows a jumbo frame (more than 8500 bytes) on 10G card within a minute, then it might be dropped. • 263512—ScreenOS 6.1.0 includes a new SSHv2 secondary login banner feature. However, unless the feature is enabled, if the secondary banner is displayed before a login prompt on a console or via a Telnet connection, no positive acknowledgment to the secondary banner is required (applicable to console, Telnet, SSHv1, and SSHv2 connections). • 263585—In certain situations, Network Address Translation (NAT) traffic using H.323 ALG resets the device. • 266022—Because the NS 5400 supports 2 million sessions by default in 6.1 (and 6.0.0r2 and later), you must ensure that the device has a minimum of 450MB of free memory when upgrading from 5.4 or 6.0.0r1 to 6.1.0 or 6.0.0r2. One million sessions require approximately 340MB of memory. • 274425—The drop of to-self IKE packets is not logged when no IKE is configured. • 312046—On some devices, an attempt to negotiate the maximum transmission unit (MTU) using the ICMP "packet too big" packet might fail. Failure to negotiate the MTU might, for example, cause an FTP session failure. The failure is caused in part because the ICMP packet is sent only once. • 387143—The alarm LED is cleared automatically without issuing the clear led alarm command. • 391304—The duration of time reported by policy traffic logs is shorter than the actual time duration. • 393301—During Web authentication, when an ACK packet was received, the firewall erroneously sent a FIN packet to end the session. • 413775—[ISG] The set sat sess-close [0|1] command did not function as expected. • 416573—When the debug command was run, the redundant debug information was removed. • 419564—The ppp multi link bundle supports only two BRI channels. Copyright © 2015, Juniper Networks, Inc. 81 ScreenOS 6.3.0 Release Notes • 427094—Occasionally, the connection between the Catalyst switch and the Copper Gigabit interface with manual duplex setting is down. • 427467—[SSG 140] The device reboots unexpectedly because of ARP traffic across bgroup interfaces. • 428914—[ISG, NetScreen-5000] When Websense was enabled, access to certain websites dropped due to application error. • 429239—When the remote authentication server was primary, the authentication failback option did not function as expected. • 431675—The defragmentation limit is changed to support up to 65535 bytes of IP packet. • 431762—During an upgrade to Release 6.1.0r5, MGCP-related messages might appear on the console. • 431944—In transparent mode, MPLS pass-through traffic is dropped. • 433456—The original source and destination address are missing from the log to USB flash. • 435348—[SSG 5/20, SSG 140, SSG 500] The firewall could reset due to an exception before the boot up process. The device shows the exception dump. • 439759—When an access list that is tied to an RP configuration for multicast is not set, the firewall might reboot. • 440546—The antivirus scanning process might get stuck the SMTP sessions, if the client is using SMTP DSN (Delivery Status Notification) and the recipient's e-mail address contains word QUIT. • 441723—Firewall does not send TCP RST for traffic matched by IPv6 REJECT policies. Performance • 297405—Inter-Vsys traffic are dropped if it do not pass through an ALG or ICMP. Routing 82 • 258978—For the SSG 320M/350M, the supported maximum number of Border Gateway Protocol (BGP) redistributed routes is 4096. However, if a large number of routes are added with an automated script, it is possible to exceed the supported limit. Routes entered or redistributed manually should not be able to exceed 4096. • 398277—OSPF adjacencies were lost due to an FPGA error. • 416966—When a route was displayed by get route command some of the flags were not freed, and the firewall rebooted. The route was frequently added and deleted by changing dynamic routing. • 430932—Secondary VPN Tunnel configured with point to multi-point OSPF stopped in ExStart. • 440113—IPv6 Neighbor solicitation messages from the source “::” are dropped by IP Spoofing. Copyright © 2015, Juniper Networks, Inc. Addressed Issues Voice-over-Internet Protocol (VoIP) • 310928, 314481—In NAT mode, the security device might stop responding under heavy Media Gateway Control Protocol (MGCP) traffic. • 421768—When the H.323 ALG was enabled, the H.323 RAS admissionConfirm packets were dropped. Virtual Private Network (VPN) • 395216—The fragmented packets of cross-chip ASIC VPN traffic were dropped. • 395312—When Baltimore Unitrust CA was used, the PKI negotiation using the SCEP failed. • 430028—The device reboots when auto renewal of the same SCEP key was performed. • 433028—The device reboots on its own when SCEP auto-renewal of the same key is performed. WebUI • 393022—ECDSA signature authentication is missing from the authentication methods list in the IKE phase 1-proposal editing WebUI page.

When the sum of the offset and size of one fragmented packet differ from that of the next fragmented packet, the packets overlap, and the server attempting to reassemble the packet can crash, especially if it is running an older operating system that has this vulnerability. After you enable the Teardrop Attack SCREEN option, and when the device detects this discrepancy in a fragmented packet. The packets are dropped. • The following information is updated in Denial of Service Attack Defenses Chapter in the Concepts & Examples ScreenOS Reference Guide: In the Attack threshold, Alarm Threshold, Source Threshold, and Destination Threshold sections the statement same destination address and port number must be updated as same destination address and ingress interface port (physical port or logical port like sub interface) in all the occurrences. The following is the list of updated thresholds: • Attack Threshold—Attack threshold is triggered based on same destination IP plus same Ingress Interface Port (physical port or logical port like sub interface) per sec required to activate the SYN proxying mechanism. NOTE: Threshold is not triggered based on Transport Layer ports (TCP ports or UDP ports). For example, if Attack threshold is 20, so if there are 20 PPS to same destination IP and on same Ingress interface, then the ATTACK threshold will be triggered. However, if there are 20 PPS to the same destination, but distributed among multiple incoming interfaces, then ATTACK threshold will not be triggered. • 102 Alarm Threshold—The value you set for an alarm threshold triggers an alarm when the number of proxied, half-completed connection requests to the same destination address and ingress interface port (physical port or logical port like sub interface) per second exceeds that value. For example, if you set the SYN attack threshold at Copyright © 2015, Juniper Networks, Inc. Errata 2000 SYN segments per second and the alarm at 1000, then a total of 3001 SYN segments to the same destination address and ingress interface port (physical port or logical port like sub interface) per second is required to trigger an alarm entry in the log. For each SYN segment to the same destination address and ingress interface port (physical port or logical port like sub interface) in excess of the alarm threshold, the attack detection module generates a message. At the end of the second, the logging module compresses all similar messages into a single log entry that indicates how many SYN segments to the same destination address and ingress interface port (physical port or logical port like sub interface) arrived after exceeding the alarm threshold. If the attack persists beyond the first second, the event log enters an alarm every second until the attack stops. • Source Threshold—This option allows you to specify the number of SYN segments received per second from a single source IP address—regardless of the destination address and ingress interface port (physical port or logical port like sub interface)—before the security device begins dropping connection requests from that source. Tracking a SYN flood by source address uses different detection parameters from tracking a SYN flood by destination address and ingress interface port (physical port or logical port like sub interface). When you set a SYN attack threshold and a source threshold, you put both the basic SYN flood protection mechanism and the source-based SYN flood tracking mechanism in effect. • Destination Threshold—This option allows you to specify the number of SYN segments received per second for a single destination IP address before the security device begins dropping connection requests to that destination. If a protected host can be reached through multiple ingress interfaces, you might want to set a threshold based on destination IP address only—regardless of ingress interface Tracking a SYN flood by destination address uses different detection parameters from tracking a SYN flood(Attack Threshold) where destination address plus ingress interface port (physical port or logical port like sub interface) is used. Consider the following case where SYN Flood Attack threshold is 20, and Interface 1 as well as Interface 2 are the ingress interfaces to reach the same server. An attacker sends 19 PPS to Interface 1 and 19 PPS to Interface 2; neither set of packets (where a set is defined as having the same destination address and same ingress interface) activates the SYN proxying mechanism. The basic SYN flood attack mechanism (ATTACK Threshold) tracks destination address and ingress interface (physical or logical like sub interface), and neither set exceeds the attack threshold of 20 pps. However, if the destination threshold is 20 pps, the device treats traffic with same destination address to both the ingress interfaces as members of a single set and rejects the 21st packet—on Ingress Interface 1 or Ingress interface 2 to that destination. • In Setting a Service Timeout section of Concepts & Examples ScreenOS Reference Guide, the behavior of timeout value function is as follows: • For 5.3.0r2 and earlier releases, when a policy is configured with multiple services or groups and if the matched service has an overlapped service timeout then the option is to select the last service timeout configured. Copyright © 2015, Juniper Networks, Inc. 103 ScreenOS 6.3.0 Release Notes • From 5.3.0r3 and later releases, when a policy is configured with multiple services or groups and if the matched service has an overlapped service timeout then the option is to select the first matching service in the policy in alphabetical order. For more information see the JTAC Knowledge base number KB11970 located at http://kb.juniper.net/KB11970 . • The following information in Service Timeout Configuration and Lookup section in the Building Blocks for Policies chapter is incorrect: Services with multiple rule entries share the same timeout value. If multiple services share the same protocol and destination port range, all services share the last timeout value configured. The correct information is as follows: Services with multiple rule entries share the same timeout value. When we set multiple services in a policy, and if these services share the same protocol and destination port range, then the service entries are arranged in alphabetical order. The first service timeout value is selected when processing the timeout lookup. • The following information in Configuring Active/Active NSRP in Transparent Mode chapter is incorrect: 2.

ScreenOS Upgrade Guide • The following note has to be added in the ScreenOS Upgrade Procedures chapter in the Figure 1: Firmware Upgrade Path NOTE: For the SSG 500 device, it is strongly recommend to update the upgrade path with the boot loader 6.0 before proceeding to the ScreenOS latest version. Copyright © 2015, Juniper Networks, Inc. 111 ScreenOS 6.3.0 Release Notes • The following note has to be added in the ScreenOS Upgrade Procedures chapter Upgrading Security Devices in an NSRP Active/Passive Configuration section in the From CLI heading after point e. NOTE: If the command save soft from tftp ip_addr screenos_filename to flash is executed while the device is still NSRP Master, then an NSRP failover would be automatically performed when executing this command. • In the ScreenOS Upgrade Procedures chapter, in Table 1: Upgrade Paths to ScreenOS 6.3.0, the upgrade recommendation (boot-loader filename) for SSG520, SSG550, SSG520M, and SSG550M is incorrect. The correct upgrade recommendation (boot-loader filename) for SSG520, SSG550, SSG520M, and SSG550M is Loadssg500v107. Limitations and Compatibility This section describes limitations and compatibility issues with the current release. Limitations of Features in ScreenOS 6.3.0 This section describes the limitations of some features in the ScreenOS 6.3.0 release. They apply to all platforms unless otherwise noted. NOTE: Transceiver Compatibility—Juniper Networks strongly recommends that only Juniper–provided transceivers be used on interface modules. Different transceiver types (long-range, short-range, copper and so on) can be used together on multi-port SFP interface modules as long as they are Juniper-provided transceivers. Juniper Networks cannot guarantee that the interface module will operate correctly if third-party transceivers are used. Please contact Juniper Networks for the correct transceiver part number for your device. 112 • Admin login sessions not cleared automatically—If the admin timeout value is set to zero using the set console time 0 command, any accidental network disconnection (For example, a cable is unplugged or the client is not closed normally) leaves the associated sessions open and leave an active entry in the admin table. The entries are not cleared until the device is reset. [281310]. • Telnet client not available from a Virtual System (Vsys)—The new telnet client from the CLI interface enhancement is not available at the Vsys level. [307763] • Fast Ethernet port trunking on ISG 1000/2000 requires consecutively numbered ports—Fast Ethernet port trunking on ISG 1000 and ISG 2000 devices has a limitation. If an aggregate interface has more than two ports defined, the ports must be numbered consecutively without interruption when they are added to the interface. Copyright © 2015, Juniper Networks, Inc. Limitations and Compatibility For example, ethernet2/2, ethernet2/1, and ethernet2/3 ports can be configured even in the order given because they are numbered consecutively. If ports ethernet2/1, ethernet2/2, and ethernet2/4 are configured, however, then sessions on this interface experience load balancing issues. This second example is not a supported or recommended configuration. • Use of DIPs and SCTP multi-homing—There are several Stream Control Transmission Protocol (SCTP) limitations when the ScreenOS devices uses DIPs. • When SCTP multi-homing is used with DIPs, there is source port translation error that results in erroneous source port translation and ultimately dropped traffic. • When DIPs are used in an SCTP multi-homing deployment, sessions cannot be immediately cleared when a shutdown message is received. Sessions are freed after a timeout. • When SCTP multi-homing is employed on a device using DIPs, not all sessions are synched by devices in an NSRP cluster. • When DIPs are used with SCTP multi-homing, SCTP heartbeat traffic is dropped by the device, thus the SCTP heartbeat function is not supported. • ScreenOS 6.3.0 does not support SCTP multi-homing when DIPs are used by the ScreenOS device. [285236, 285672, 285722, 285988] • 8G2-G4 card throughput stability—Running repetitive maximum throughput tests at certain small frame sizes, can cause a variance of up to about 14% difference in throughput between two test cycles. The behavior is restricted to the 8 port G4 card. This does not jeopardize customer traffic in any way. • NetScreen 5000 series throughput stability—For NetScreen–5000 8G2-G4, a hardware limitation might result in degraded throughput stability. This limitation is also present in ScreenOS 6.0.0 and 6.1.0. [287811] • TCP and UDP sweep screen attack monitoring—The TCP and UDP sweep screen check is insufficiently accurate. Under extended testing, the TCP and UDP sweep screen sometimes reports benign traffic or below-threshold attacks as valid sweep attacks. [293313] • Virtual MAC Address duplication—Because ScreenOS derives VMACs based on information taken from cluster ID, interface ID, and VSD, it is not permitted to use the same clusters and VSDs on the same broadcast domain. If cluster IDs and VSDs are duplicated on a broadcast domain, it might result in the same VMAC being assigned to more than one interface or device. [300933] • PIM Power and Thermal Requirements—If you install either 8-port or 16-port uPIMs in your SSG 140, SSG 500-series, or SSG 500M-series device, you must observe the power and thermal guidelines. Please refer to the PIM and Mini-PIM Installation and Configuration Guide for the power and thermal guidelines for all supported platforms, available at: http://www.juniper.net/techpubs/hardware/pim_guide/pim_guide.pdf . Copyright © 2015, Juniper Networks, Inc. 113 ScreenOS 6.3.0 Release Notes WARNING: Exceeding the power or heat capacity of your device might cause the device to overheat, resulting in equipment damage and network outage. 114 • NSRP—NSRP is not supported on WAN interfaces. Devices with WAN interfaces can use NSRP, but the WAN ports do not automatically failover as the Ethernet ports do. • Flood Screens—On ISG 1000, ISG 2000, NetScreen-5000 Series devices, the UDP and ICMP flood screens apply to the physical interface and therefore require that the zone be bound to a physical interface. The following limitations apply: • When zones are bound to a sub-interface, the ICMP and UDP flood screens are not enforced unless the zone is also bound to a physical interface. • When ICMP and UDP flood screen options are configured for different zones and on the same physical interface, the flood threshold is applied based on the last configured zone threshold. • When ICMP and UDP flood screen options are applied to a zone tied to multiple physical interfaces, the entire threshold value is applied to each of the physical interfaces. • For reference, the High Availability (HA) zone does not allow any screen features to be configured. • UDP and ICMP Flood Screening—ScreenOS 6.3.0 does not support UDP and ICMP flood screening for aggregate interfaces in ISG and NetScreen 5000 series. [428057] • Configuration file downloads through WebUI without authentication—Using the WebUI, the firewall downloads the configuration file without authentication. For more information, see the JTAC knowledge base number KB 12943 located at http://kb.juniper.net. • Call unhold fails—According to RFC 3261, a calling party shall use a=sendonly to hold a call and a=sendrecv to unhold it. The observed behavior of the SIP phone used in our testing is that it does not include the a=sendrecv command when it tries to unhold a call. This lack causes the SIP server to return a "500 internal error" response because it is unable to determine the state of the transaction. This problem is a telephony system issue that cannot be resolved by ALG. Hence, there is no work around for this issue available through a firewall. [300723]. • Maximum number of OSPF Redistributed Routes—For the SSG 320M/350M , the supported maximum number of Open Shortest Path First (OSPF) redistributed routes is 4096, but it might be possible to exceed the maximum. OSPF redistributed routes are handled in two parts: route task and OSPF task. The route task adds redistributed routes to OSPF continuously during one CPU time slice. The redistributed routes counter are not, however, updated until the OSPF task is processed by the CPU, so more routes might be added in OSPF when the routes are added using an automated script. Routes entered or redistributed manually should not be able to exceed 4096. [258979] • ISG and NetScreen 5000 series Multicast Hardware Support—Multicast sessions can be handled by the ASIC only if there is a single output interface per virtual router. Copyright © 2015, Juniper Networks, Inc. Documentation Changes The mcast group address can be pushed to ASIC so frames are forwarded in hardware. To use this feature run the set/unset flow multicast install-hw-session command. [309007, 427260] • HA pair on ISG2000 devices—Currently ScreenOS does not support redundant or aggregate interfaces in an active-active HA pair on ISG2000 devices. Packets received on the backup device cannot pass through the cluster in an active-active ISG2000 pair. • ASIC Hardware Support—ICMP-flood and UDP-flood detections are done by ASIC on high-end platforms such as ISGs and NS-5000. There is no detection method to let the ASIC know if the alarm-without-drop is configured. Therefore, the ASIC drops the attack packets. On SSG series, the flow CPU detects and determines if the alarm-without-drop is configured or not and takes appropriate actions. • Policies—Policy Verification exec policy verify command is not supported for IPv6 policies. It is only supported for IPv4 policies. • ICSA —ScreenOS captures raw IP packets of types 0, 6, 17, 43, 44, and 60 to the packet log when the set flow log-dropped-packet and set firewall log-illegal-packet commands are configured. The packet log may be accessed through the command get log packet. However, the packet log is available only on the device. It may not be transmitted to an external syslog server. • Client-to-Site IPv6 VPN Support—IPv6 IP pools are supported in the IKEv1 protocol, but they are not supported in the L2TP, PPP, and IKEv2 protocols.
