It sounds like their system is balancing at a high level (like http
traffic), rather than the raw IP data. This might have the advantage of
being able to inspect URLs and route accordingly, but a lack of IP will
cause you problems with sessions.
If you want a commercial, supported version of this you could look at
http://www.sentralsystems.com/load.html (UK) which includes a HA pair
running heartbeat. Certainly their systems present as the correct IP.
In any case, a properly configured system running ldirectord should be able
to do the job for you.
