This example shows how to use the Nebula firewalls (USG FLEX/ATP series models) to establish IPSec Site to Site VPN tunnel between USG FLEX H series models. It explains how to configure the Nebula Site-to-Site VPN using the Nebula Control Center. Once the Site-to-Site VPN tunnel is established, LAN hosts can communicate with each other through the VPN tunnel seamlessly.

Set Up the Site-to-Site VPN settings on the Nebula Firewall

On Nebula Control Center, navigate to Side-wide > Configure > Firewall > Site-to-Site VPN > Configure the Primary interface, and Secondary interface (backup interface), on the local networks, enabling the interface will require routing through the VPN. Enable the Nebula VPN and choose the Site-to-Site VPN topology.
