I see the same issue, with a little different settings. I am working on with 2 x directors, 3 x worker bees in an LVS-DR environment. Currently all systems are RHEL4 and UltraMonkey3 has been running on the directors. The closest that UM3 comes to working in this environment is as you mentioned above: connections marked as inactive by the live director, but packets never get from the live director to any of the worker bees (as per many tcpdumps on both hosts).

Frustrating.
