You can switch the active log file by running fw logswitch on the Management Server1. This command closes the current log file and creates a new one2. It is useful for archiving or backing up log files, or for creating a new log file for a specific time period2. You can also schedule the log switch to occur automatically at a regular interval, such as daily, weekly, or monthly2. To run this command, you need to access the Management Server in expert mode and run fw logswitch1. You can also use the SmartView Tracker to switch the active log file from the GUI. To do this, go to the Network & Endpoint tab, click on the File menu, and select Switch Active File…3.

After trust has been established between the Check Point components, the Security Gateway IP address cannot be changed without re-establishing the trust. This is because the trust is based on the Secure Internal Communication (SIC) mechanism, which uses certificates to authenticate and encrypt the communication. The certificates are issued by the Internal Certificate Authority (ICA) of the Security Management Server / Domain Management Server, and contain the name and IP address of the component. Therefore, if the IP address of a component is changed, the certificate will become invalid and the trust will be lost. To restore the trust, the certificate must be renewed or reissued by the ICA12.

However, there are some exceptions to this rule. The Security Gateway name can be changed in command line without re-establishing trust, as long as the IP address remains the same. This is because the SIC mechanism does not rely on the hostname, but on the IP address and the SIC name (which is usually derived from the hostname, but can be manually changed). The Security Management Server name can be changed in SmartConsole without re-establishing trust, as long as the IP address remains the same. This is because SmartConsole uses a different mechanism to connect to the Security Management Server, which does not depend on the SIC certificate. The Security Management Server IP address can be changed without re-establishing trust, as long as some steps are followed to update the Check Point Registry file on the managed Security Gateways / Cluster Members / VSX Virtual Devices. This is because the Registry file contains the IP address of the ICA, which is used for certificate renewal. If the Registry file is not updated, then the certificate renewal will fail and the trust will be lost3.

 In the Check Point Firewall Kernel Module, each kernel is associated with a key, which specifies the type of traffic applicable to the chain module. For Wire Mode configuration, chain modules marked with 1 will not apply, as they are related to NAT, VPN, or other features that are not supported in Wire Mode. Wire Mode is a mode of operation that allows transparent traffic forwarding without any inspection or modification by the firewall.
