VPN offers a secure, efficient, and economical way to connect physically separate networks and lets users access corporate network resources from a remote location.
The Barracuda NG Firewall provides three types of VPN services:
- Client-to-Site VPN – Lets remote users access the corporate network with VPN clients and mobile devices.
- Site-to-Site VPN – Securely and transparently connects remote locations with your network.
- SSL VPN – Lets remote users access corporate resources over a secure web interface without the need of configuring a VPN client.
Client-to-site VPN
Client-to-Site VPN offers users access to the corporate network from a remote location over a secure tunnel connection. Clients authenticate by user/password and/or X.509 certificates. Depending on the VPN client device, the Barracuda NG Firewall supports TINA or VPN protocols. Mobile devices running iOS or Android can connect using IPsec with pre-shared keys.
For more information, see Client-to-Site VPN.
Site-to-site VPN
Site-to-Site VPNs establish secure connections between two locations over a public network such as the Internet. The proprietary TINA protocol offers intelligent traffic management capabilities using Traffic Intelligence, WAN optimization, and on-the-fly traffic shaping. For connectivity with third party VPN gateways, it is also possible to create Site-to-Site VPN connections using IPsec.
For more information, see Site-to-Site VPN.
SSL VPN
SSL VPN grants users secure SSL/TLS-encrypted access to internal corporate resources and applications through a customizable web interface without the need of installing or configuring a VPN client. SSL VPN supports centralized authentication, authorization, and content inspection. Server and application URLs are translated into a URL namespace, making resources accessible via a single hostname.
