What is the Security Gateway directory where an administrator can find vpn debug log files generated during Site-to-Site VPN troubleshooting?

When troubleshooting a Site-to-Site VPN on a Check Point Security Gateway, debug logs are generated using commands like vpn debug. The output of these debugging processes is written to log files located in the $FWDIR/log/ directory. The primary file for VPN debug information is vpn.elg. This directory is the central repository for all Security Gateway operational logs, including firewall logs (fw.log) and various debug outputs. The variable $SFWDIR in the question is a common typo for the standard environment variable $FWDIR.

A. $FWDIR/conf/ is the directory for storing configuration files, such as rulebases and network objects, not for runtime log files.
B. $CPDIR/conf/ contains general Check Point product suite configuration files. Also, $SCPDIR is not a standard Check Point environment variable.
D. This is an incorrect, hardcoded path. The standard location for VPN logs is within the $FWDIR/log/ directory, not a separate /vpn/log/ subdirectory.

1. Check Point Support Center, sk103372, "How to debug VPN issues on Security Gateway": This official document explicitly states in the "Kernel Debug" section for IKEv1 and IKEv2, "The debug output is written into the $FWDIR/log/vpn.elg file." This confirms the log file's location.

2. Check Point R81.20 Security Gateway Administration Guide, Chapter "Logging and Monitoring", Section "Log Files": This guide details the purpose of various directories. It specifies that the $FWDIR/log/ directory is the location where the Security Gateway stores its log files, including the firewall log (fw.log) and debug logs.

3. Check Point Support Center, sk111516, "File System Directories on Gaia OS": This article describes the Check Point directory structure. It defines $FWDIR as the firewall product directory and confirms that $FWDIR/log is the designated location for log files generated by the firewall and other security blades.
