The standard deployment makes the Barracuda Link Balancer the default gateway for the client's network.
Placing the Barracuda Link Balancer between the Internet and switch lets administrators use the Barracuda Link Balancer to apply traditional network firewall rules including DHCP and DNS services to local clients.
An optional deployment configuration places the Barracuda Link Balancer on the perimeter between the Internet and a network firewall for local network address translation.
The Internet links plug into the Barracuda Link Balancer's WAN ports while the firewall connects to the LAN port.
Barracuda Link Balancers can be paired for high availability in an active-passive cluster. High availability is easy to set up. Using the web UI, administrators simply point the secondary Barracuda Link Balancer to the primary Barracuda Link Balancer's management IP address. Configurations synchronize automatically.
High-availability deployment is based on the Virtual Router Redundancy Protocol (VRRP) with the clustered devices sharing a virtual IP address. The passive device will take over and handle all traffic upon failure of the active device. Please refer to the Barracuda Link Balancer administration guide for other deployment options.
High Availability: Integrated Firewall
High Availability: Single Firewall
High Availability: Dual Firewall
Set it and Forget it
Fast Link Balancing. Faster Administration.
Administrators configure the Barracuda Link Balancer through an intuitive UI.
The configuration screens presented in the UI give administrators precise control over every feature and enable easy firmware and security upgrades.
Status screens give administrators real-time visibility into network traffic statistics, usage and availability.
Bandwidth management and Quality of Service are easy to understand. Simply assign high, medium or low priority to each application.
Plug it in. Turn it on. Done.
It Couldn't be Easier
Simply plug Internet connections into the Barracuda Link Balancer's WAN ports and define the speed of each connection.
Next, configure DHCP or static IP WAN IP addresses.
The Barracuda Link Balancer automatically sends client requests to the healthiest link that has the most Internet bandwidth available.
