Check Point and Firebox BOVPN Integration Guide (2024)

Deployment Overview

WatchGuard provides integration instructions to help our customers configure WatchGuard products to work with products created by other organizations. If you need more information or technical support about how to configure a third-party product, see the documentation and support resources for that product.

This integration guide describes how to configure a Branch Office VPN (BOVPN) between a WatchGuard Firebox and a Check Point device.
