My original statement assumed that LVS load balances on the 
tuple CIP, VIP:vport. It now occurs to me that LVS might 
load balance on CIP:cport,VIP:vport. This is a really basic 
fact. I'm sure I knew the answer at one stage, but I've 
forgotten and can't find anything on it in the HOWTO or 
the documentation at www.linuxvirtualserver.org. I also 
notice that like the HOWTO, the rest of the documentation 
was largely written in the era of the 2.0.x and 2.2.x 
kernels.

Horms, Graeme,

 	If an LVS-DR director is sitting inside a nat 
router, so that all calls from the internet arrive at the 
director from the private IP on the inside of the router, 
will the director loadbalance (differentiating the incoming 
connections by the various cports) or not loadbalance (all 
connections come from the router's IP).
