Symptoms

• When the Security Gateway is configured in Non-Transparent Proxy Mode, the 'Destination' field in the URL Filtering logs is the Security Gateway's proxy interface. In the log with the client source IP address, there is no indication of the actual IP address of the target website.

Cause

This is by design. When you use a Non-Transparent proxy, the Security Gateway splits the connection and connects to the target destination sourced from the gateway instead of to the client. The client-based log shows a connection to the proxy interface of the Security Gateway.

Solution

This problem was fixed. The fix is included in:

• Check Point Quantum R82
• Jumbo Hotfix Accumulator for R81.20 starting from Take 26
