| ID | Symptoms | | - | There is no upgrade path for "NGX R65 CoreXL LA". Perform a clean installation of any version R70 and higher. | | 00426948 | It is not possible to upgrade Power-1 appliances that run with "R65 CoreXL" image. It is necessary to "Restore to Factory Defaults" and choose the non-CoreXL R65 image. Only then, the upgrade can be performed. After upgrade, CoreXL can be enabled via "*cpconfig*" menu. | | - | 3rd party clusters are not supported. **Note:** IPSO OS with Check Point R70 version and higher fully supports CoreXL. | | 00417896 | Connections will be dropped during *any* ClusterXL upgrade method (including "Full Connectivity Upgrade"; refer to [sk107042](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk107042)) if the number of CoreXL FW instances is different on cluster members. Before starting any upgrade, configure the same number of CoreXL FW instances on all cluster members. In addition, refer to [sk42096 - Cluster member is stuck in 'Ready' state](http://supportcontent.checkpoint.com/solutions?id=sk42096). | | - | CoreXL is supported on StandAlone machine starting from R70. | | 00417888 | These features/settings are ***not*** supported in CoreXL: |----------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **Limitation** | **Comments** | | Check Point QoS (Quality of Service) | Supported by default in R77.10 and higher (refer to [sk98229](http://supportcontent.checkpoint.com/solutions?id=sk98229)) | | 'Traffic View' in SmartView Monitor | All other views are available. Supported by default in R80.10 and higher (because the MultiCore VPN is integrated - [sk118097](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk118097)) Supported in R77.20 with *Take_169* of R77.20 Jumbo Hotfix and with MultiCore VPN Hotfix (contact [Check Point Solution Center](mailto:solcenter@michael.checkpoint.com)). **Important Note:** MultiCore VPN Hotfix is *not* available for the R77.30 version. | | Route-based VPN | Supported by default in R75.40 and higher (refer to [sk76800](http://supportcontent.checkpoint.com/solutions?id=sk76800) and to [sk105886](http://supportcontent.checkpoint.com/solutions?id=sk105886)) | | IP Pool NAT | Supported by default in R75.40 and higher - only on Gaia / SecurePlatform / XOS | | IPv6 | Supported by default in R80.10 and higher. Requires the LTE Hotfix for R7x versions: * R77.10 - [sk100446](http://supportcontent.checkpoint.com/solutions?id=sk100446) * R76 - [sk95768](http://supportcontent.checkpoint.com/solutions?id=sk95768) * R75.40VS - [sk91621](http://supportcontent.checkpoint.com/solutions?id=sk91621) | | Firewall-1 GX | Supported by default in R80.10 and higher.

To preserve consistent configuration, before enabling one of the unsupported features, deactivate CoreXL via "*cpconfig*" menu and reboot the Security Gateway (in cluster setup, CoreXL should be deactivated on all members). | | - | In Security Gateways R77.30 and lower, when CoreXL is enabled, *VPN* traffic inspection occurs *only* in global CoreXL FW instance #0 (*fw_worker_0* ). By design, global CoreXL FW instance #0 (*fw_worker_0*) always runs on the CPU core with highest ID (as allowed by the current CoreXL license). Note: Starting in R80.10, VPN Multi-Core feature allows CoreXL to inspect VPN traffic on all CoreXL FW instances. Refer to [sk118097](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk118097). | | - | In Security Gateways R77.30 and lower, when CoreXL is enabled, *VoIP* control connections are processed *only* in global CoreXL FW instance #0 (fw_worker_0). By design, global CoreXL FW instance #0 (*fw_worker_0*) always runs on the CPU core with highest ID (as allowed by the current CoreXL license). | | - | Maxumal number of CoreXL FW instances is limited.
