Test the connection by using a web browser from the Internet (not inside the LAN) to establish an SSL connection to the external IP
address of your corporate firewall. For example, if your firewall's external IP address is 23.45.67.89, go to in
https://23.45.67.89
your browser.
When you are prompted to accept an SSL certificate, accept the warning and proceed to load the page. untrusted
If you see the Barracuda SSL VPN login screen, this confirms that your appliance can receive connections from the Internet.

High Availability Deployment
High availability is available for the Barracuda SSL VPN 480 and above. Clustering two or three Barracuda SSL VPNs provides you with a
high-availability, fault-tolerant environment that supports data redundancy and centralized policy management. After you configure one HA unit,
configuration settings are synchronized across the cluster. You can cluster the Barracuda SSL VPN in two ways: simple high availability or high
availability with a load balancer.
Simple High Availability
If you configure two or more Barracuda SSL VPNs in a high availability setup without a load balancer, configurations are synced between the
units but only one unit processes traffic. The secondary unit is passive and monitors the health of the primary unit. If the active system becomes
unavailable, the secondary unit takes over automatically.
For more information, see How to Configure a High Availability Cluster .
High Availability with a Load Balancer
If you want all clustered Barracuda SSL VPNs to process traffic, use a load balancer (such as the Barracuda Load Balancer) to direct traffic to the
HA units while maintaining session persistence. You must have a load balancer to spread the load over all Barracuda SSL VPN cluster members.
It is recommended that you configure the Barracuda Load Balancer in Bridge-Path (recommended) or Route-Path mode.
To cluster your Barracuda SSL VPNs with a load balancer, complete the following tasks:
Configure the Barracuda Load Balancer. For instructions, see or Barracuda Load Balancer Bridge-Path Deployment How to Set Up a

Follow these instructions to cluster your Barracuda SSL VPN systems. These
instructions apply to both simple high-availability and for clustering with a load
balancer.
