First, the initial IP address that is obtained is assigned by AWS using Dynamic Host Configuration Protocol (DHCP). The LoadMaster obtains this address at instantiation and uses it as its interface address. This address is permanent for this instance and this private address is associated with a public IP address as well. Additional private addressing can be assigned according to your needs if you have additional private networks in AWS.

In addition, a public address that maps to the private address is issued by AWS. Unlike the private address, the public IP address can be changed by purchasing an Elastic IP.

Note: For more information on Elastic IPs, refer to the Amazon EC2 Elastic IP Addresses Feature Guide. Elastic IPs can be requested by opening a Support case with AWS. Elastic IPs can be allocated in the AWS EC2 Console in NETWORK & SECURITY > Elastic IPs.

Interface IP addresses can be changed administratively as usual from the LoadMaster, but this requires an additional AWS configuration to prevent disconnection.

To preserve public ports, the Web User Interface (WUI) is available on port 8443 rather than 443. This allows port 443 to be used for a Virtual Service.

Note: Due to AWS limitations, it is not possible to bond interfaces on AWS LoadMasters.
