Configuring a Persistent IP Address

When you create an instance of your Barracuda Message Archiver appliance, a public IP address is associated with the instance. This public IP address changes if the instance is stopped or terminated. To address this issue, you can assign a persistent public IP address to the instance using Elastic IP addressing. For more information, see the Amazon Web Services article Elastic IP Addresses.

2. From the EC2 dashboard, select Elastic IPs under NETWORK & SECURITY.
3. Click Allocate New Address; click Yes, Allocate to confirm and allocate a new IP address. A random Public IP address is generated and displays in the Allocate New Address table.
