Follow the steps in the article, I've made some progress.
On the director:
[root@alpha2 /root]# tcpdump -ln host 192.168.193.158
Kernel filter, protocol ALL, datagram packet socket
tcpdump: listening on all devices
16:48:17.365911 eth0 < 192.168.193.158.3597 > 192.168.193.224.www: S 3688807335:

The request is serverd by the lvs box.
[root@alpha2 /root]# ipvsadm -ln
IP Virtual Server version 0.9.7 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.193.224:80 wlc
-> 192.168.194.111:80 Masq 1 0 0
on the real server:
[root@alpha /root]# tcpdump -ln host 192.168.193.158
Kernel filter, protocol ALL, datagram packet socket
tcpdump: listening on all devices
there is no request to reach the real server.
The commands I've issue are :
echo "1" >/proc/sys/net/ipv4/ip_forward
echo "1" >/proc/sys/net/ipv4/ip_always_defrag
ipchains -A forward -j MASQ -s 192.168.194.0/24 -d 0.0.0.0/0
ipvsadm -A -t 192.168.193.224:80 -s wlc
ipvsadm -a -t 192.168.193.224:80 -r 192.168.194.111:80 -m
I'm so doubt why the request is directly taken over by the lvs box.
Is my network or ipchain's configure wrong?
the network likes it :
192.168.193.158(CIP)
