Barracuda CloudGen Firewall

Attention

Barracuda CloudGen Firewall version 8.0 is a cloud-only version. It is currently not available for on-premises deployments and can only be deployed in Microsoft Azure, Amazon Web Services, or Google Cloud Platform public clouds.

Site-to-Site VPN

  • Last updated on

A site-to-site VPN allows multiple locations to establish secure connections over the Internet or other public networks. VPN tunnels transparently join IPv4 networks, making remote resources securely available to clients behind the VPN devices through the tunnel. The VPN service supports both IPv4 and IPv6 for the VPN envelope. The traffic passing through the VPN tunnel is limited to IPv4. The Barracuda CloudGen Firewall offers two VPN protocols: TINA and IPsec.

TINA VPN

TINA is a Barracuda Networks proprietary VPN protocol designed to extend the feature set and to remove the limitations of the IPsec protocol. TINA is designed to provide superior VPN connectivity and availability. Site-to-Site TINA tunnels can only be established between CloudGen Firewalls. Advanced VPN features, such as Traffic Intelligence or WAN Optimization, are only available for TINA VPN tunnels.

For more information, see TINA VPN Tunnels.

IPsec VPN

IPsec has established itself as the standard for VPN tunnels and is widely supported by almost all VPN device manufacturers. The Barracuda CloudGen Firewall supports both IKEv1 and IKEv2 IPsec Site-to-Site VPN tunnels to third-party VPN devices.

For more information, see IPsec VPN Tunnels.

Creating VPN Tunnels Using the Control Center GTI Editor

The Barracuda Firewall Control Center includes the GTI Editor, a graphical interface to create and manage IPv4 and IPv6 TINA and IKEv1 IPsec VPN tunnels. When configuring VPN tunnels manually, there are many identical configuration steps and settings. The GTI Editor eliminates many of these redundant steps, helping you configure your VPN tunnels more quickly.

For more information, see GTI Editor.
