Could you please address this to the piranha-mailinglist? Not because we're
not willing to help you but because you're using a special version of the
linux virtual server which needs the support of RedHat itself. If you however
decide to grab a fresh kernel and patch it with the patches from
www.linux-vs.org
itself and you still can get it working, we definitely can help much better.

How do you stop nat? Are you definitely sure it shutdowns eth0 too?

This is when NAT is not setup correctly. What are the ipchains rules on
the director itself?

Try to address this issue in the piranha-mailinglist.
