Aye - the ip address on the realserver is .57 - just a typo on the
writeup.

>From what I understand there is no arp issue with dual nics and ipvs
nat.

The problem is that while the packet leaves the director on the right
interface - it never arrives at the realserver.

I've been exploring further - new vm's at the hosting env and a clean
env at the lab - repeating the setup  step by step.  Locally it works -
remotely at the hosting env it doesn't.

Regards,

David


Which leads me to believe it's an issue with the underlying VM
provider(xen) at the hosting environment.
