Office Mode enables a Security Gateway to assign a remote client an IP address. The assignment takes place once the user connects and authenticates. The assignment lease is renewed as long as the user is connected.

CPInfo is an auto-updatable utility that collects diagnostics data on a customer's machine at the time of execution and uploads it to Check Point servers (it replaces the standalone cp_uploader utility for uploading files to Check Point servers).
The CPinfo output file allows analyzing customer setups from a remote location. Check Point support engineers can open the CPinfo file in a demo mode, while viewing actual customer Security Policies and Objects. This allows the in-depth analysis of customer's configuration and environment settings.
When contacting Check Point Support, collect the cpinfo files from the Security Management server and Security Gateways involved in your case.
