If you run tcpdump on the Xen bridge interface logically "facing" the
realserver VMs, do you see any packets being forwarded? I don't think
you do, but if you could clarify that it'd help.

I've a sneaking suspicion this is happening because the VMs appear local
to dom0 - because they are local, since all domU instances are logically
"underneath" dom0. Although... reading back, you say:

"a"? Singular? That doesn't mesh with the config you've shown us; it
looks like the realservers are "separated" - either physically or via

A bit of clarification, if you please!
