Firewall28. When using SmartDirectory server for internal password authentication, if theaccount lockout feature is disabled the Firewall will not attempt to modify theuser's login failed count and last login failed attributes on the SmartDirectoryserver. This improves overall performance and eliminates unnecessarySmartDirectory modify errors when using SmartDirectory servers that do not havethese attributes defined because they did not apply the Check Point SmartDirectoryschema extension on the SmartDirectory server.29. Issues may arise when using automatic or partially automatic client authenticationfor HTTP on Load Sharing clusters (both ClusterXL and OPSEC clusters). Aworkaround is to define a decision function based only on IP addresses in order forconnections to open. For ClusterXL, go to the ClusterXL tab > Load Sharing >Advanced, and select IPs only. For OPSEC clusters, refer to the productdocumentation for more information.30. Definition of nested RADIUS Server groups is not supported.Security Servers31. The HTTP Security Server handles a proxied or a tunneled connection requestdifferently than earlier Firewall versions. Beginning with FireWall-1 NG FP2, suchrequests are not allowed if they are matched with an Accept rule. However, they arestill allowed if the request is matched with an Authentication or a Resource rule.This change was done in order to harden security and prevent the CONNECT fromlooping to the Security Server and then to another destination.In R54, FTP over HTTP proxy connections were allowed when using UserAuthentication even if they were not allowed explicitly by a rule in the SecurityPolicy. In NGX (R60A), in order to further harden security, these connections arenot allowed by default unless there is an explicit rule (using a URI Resource) thatallows them. If you wish to revert to the old behavior refer to SecureKnowledgesolution sk14608.32. UFP counters available via cpstat fw -f ufp give incorrect values.33. If web browsers are configured to use an IP address for their proxy (instead of ahostname), the next proxy definition of the HTTP Security Server must also use thesame IP address. If the next proxy definition is a hostname, connections using anIP address will not be allowed to the proxy. It is recommend to use only hostnamesin the browser configuration.34. When a field in a URI specification file is too long, the Security server exits whentrying to load the file. Under load, the Firewall daemon (FWD) reloads the securityserver, which then exits. After a certain time cores are dumped.35. Client authentication with agent automatic sign on is supported with all rules, withtwo exceptions:Enterprise Suite NGX R61 Known Limitations Supplement Last Update — February 7, 2007 6
• The rule must not use an HTTP resource.• Rules where the destination is a web server.Firewall36. Security Servers are not supported with Sequence Verifier in Load Sharing Clusterenvironments.37. When using the HTTP Security Server in proxy mode (HTTP Tunneling), connectionsmay be encrypted over port 80 (e.g., the first command is in the clear, andsubsequent requests are in SSL). SmartDefense will block these connections andgenerate the following log entry: Binary character in request. To enable suchconnections, change the global property asm_http_allow_connect to True. Pleasenote that this change will cause SmartDefense to stop examining these connectionswhen an HTTP Connect command is detected in the proxied connection.38. When using SOAP filtering in the HTTP Security Server, the SOAP scheme filesupports all forms of namespaces and methods, however, the feature is notsupported if a method has no namespace at all.Services39. No warning is generated when a policy containing services with the Keepconnections open after Policy has been installed checked is installed on NG FP3modules. Such services will be enforced according to the default behavior on thesemodules.40. When CIFS resources are used in rules with policy targets in their Install On fields,policy installation on NG FP3 modules may succeed without warning, althoughCIFS resource filtering is not supported on these modules.41. A service using the FTP_BASIC protocol type cannot be used with the FTP SecurityServer.42. When using T.120 connections, make sure to manually add a rule that allows T.120connections.IPv643. In IPv6 logs, IPv6 address resolving is not supported in SmartView Tracker.44. Discovery traffic is enabled by default on IPv6 enabled modules. To disable it, editthe file $FWDIR/lib/implied_rules.def and comment out the line #defineACCEPT_DISCOVERY 1.45. Anti-spoofing is currently not supported with IPv6.46. Boot policy is not supported on IPv6 enabled modules.Enterprise Suite NGX R61 Known Limitations Supplement Last Update — February 7, 2007 7
