additional information:

The command "ipvsadm -Lcn" shows reasonable values:

[root~]# ipvsadm -Lcn
IPVS connection entries
pro expire state       source             virtual            destination
TCP 00:40  SYN_RECV    194.76.232.147:50297 194.76.232.133:80  127.0.0.1:80
TCP 00:13  SYN_RECV    194.76.232.167:19410 194.76.232.133:80  127.0.0.1:80

but no packet is going to 127.0.0.1:80 as tcpdump shows.
