I already setup my rules in ipvsadm. However, its not connecting to the real 
server. Here is the procedure in my VIP

(not real ip address)

ipvsadm -A -t 202.81.26.31:80 -s wlc
ipvsadm -a -t 202.81.26.31:80 -r 202.81.26.40:80 -i -w 1
ipvsadm -a -t 202.81.26.31:80 -r 202.81.26.35:80 -i -w 2

I also enable tcp forwarding "echo 1 > /proc/sys/net/ipv4/ip_forward" just to 
be sure it can forward packets.

I'm also sure I can telnet to port 80 both on 202.81.26.40 and 202.81.26.35 but 
still I can't telnet using 202.81.26.31

Is there a problem in my sample configuration? Do I need to configure something 
on the real server.

I tried to disable selinux and iptables and do again a telnet but it is still 
unaccessible to 202.81.26.31.

Here is the result of ipvsadm -L

[root@LVS ~]# ipvsadm -L
