The Barracuda Link Balancer automatically evaluates connections using saturation, availability, latency, and performance. Taking these conditions into account, the Barracuda Link Balancer dynamically selects the best link to handle Internet traffic.
Administrators can choose from dozens of predefined applications or apply QoS rules to selected custom port ranges.
Yes. The Barracuda Link Balancer integrates both DHCP and DNS caching servers to simplify managing IP networks.
Yes. The Barracuda Link Balancer can pass VPN traffic using 1:1 NAT or port forwarding.
Yes. As an appliance designed for the perimeter, the Barracuda Link Balancer offers firewall functions to maximize the number of active Internet connections. By offering traditional firewall features such as network address translation (NAT), 1:1 NAT, and port forwarding, as well as DCHP and DNS caching services, the Barracuda Link Balancer increases the availability of Internet links to the network without the cost of more bandwidth.
Yes. The Barracuda Link Balancer provides inbound link balancing and failover through authoritative DNS services. Traffic inbound to host machines can be balanced across multiple links without using special routers, Border Gateway Protocol (BGP), or additional ISP support. Configuration is as simple as assigning each host a different Internet IP address for each Internet link used to reach it. The Barracuda Link Balancer can then distribute inbound traffic across multiple Internet links to the host by returning the IP address of the most appropriate Internet link when responding to DNS queries.
Yes. A pair of Barracuda Link Balancers can be setup as an active-passive cluster for high availability deployment. The two devices share a virtual IP address with automatic failover and failback. Clustering synchronizes configuration settings between the devices. High availability deployment is possible when the Barracuda Link Balancer is used as a firewall or as a transparent device in front of a firewall.
It depends on the situation. When there are multiple concurrent data transfers taking place between different sets of hosts, the Barracuda Link Balancer balances the respective connections across the available links, preventing congestion or saturation to guarantee the quickest possible download.
However, if there is no congestion or link saturation, then the short answer is no.
The product data sheet provides the number of maximum remote IPsec peers for each model. This assumes a single local subnet to remote subnet transport over a given tunnel, referred to as a phase 2 entry. Multiple transports would reduce the capacity.
For example, the model 330 supports a maximum of 20 VPN peers. However, if each tunnel to the peers has two phase 2 entries, then the effective number of maximum VPN peers would be 20/2 = 10. Also note that the maximum number of phase 2 entries supported per tunnel is three.
