Site-to-Site VPN

  • Last updated on

Site-to-site VPN allows offices in multiple locations to establish secure connections with each other over a public network such as the Internet. Site-to-site VPN extends the company´s network, making resources available to employees at other locations. The Barracuda NG Firewall establishes strongly encrypted VPN tunnels, using DES, 3DES, AES-128, AES-256, etc. It supports active and passive tunnel initiation and provides maximum flexibility. Furthermore, it is capable of establishing IPsec VPN tunnels to third party systems. Barracuda NG Firewall models F300 and below allow a peak amount of 256 concurrent VPN tunnels and 512 concurrent VPN transports (throughout all open tunnels added up), whereas the bigger F400 and above, tunnels and transports are only limited by hardware performance and bandwidth.
This section contains articles on how to create VPN tunnels and configure traffic flow between the connected locations.
