Consultronics Limited has at its head office a perimeter network (DMZ), of which the outer and inner bastions are pairs of Linux machines. At the time of writing, these are running kernel 2.4.13-ac4 with heartbeat-0.4.9.0k to provide service IP addresses. Our marketing folks want 24x365 availability of www.consultronics.com (we sell in 80 countries and the sun never sets on our customer base), and the financial and manufacturing staff want to be sure of access (through the tri-homed inner bastion) to the inner sanctum where the company's ERP system is kept. Running heartbeat on the bastions was a first step: the intent is to make the webserver itself an HA pair and to add a secondary route to the Internet to back up the existing T1.
