These ranges are only for the connections created from
the 2.2 masquerading code, not for the LVS connections:

There are no connection limits in LVS, they are in TCP,
there are 65536*65536 possible combinations between two IPs.
In LVS setup with one VIP:VPORT used, the number is 65536
connections from CIP to same VIP:VPORT.
