        Your guess is wrong, it works even for your setup :)

        Hey,  this program tests  the director's throughput,
not  the  real service.   LVS does  not use  the destination
address  as hash key for the connection table, why to change
it  on each packet.  In the  real servers we only detect the
incoming   packets.  They  don't   reach  the  sockets.  The
destination address is fixed intentionally.

        To  test squid  you need  another testing  tool. You
have  to read the README file  again. Of course, you can hit
the  real servers, may be to test the SYN cookies support :)
testlvs   sends  only  TCP  SYN  packets.  It  can't  create
