LVS_DR 安装后无法转发真实服务器

最近在学习LVS,现遇到如下问题
在VM下面使用4台安装CENTOS 5.3 64位系统进行实验
虚拟地址为:192.168.47.200
LVS1:192.168.47.130
LVS2:192.168.47.131
realserver1:192.168.47.132
realserver2:192.168.47.133

在lvs1和lvs2上安装配置ipvsadm和keepalived

在realserver1和realserver2 上只设置lvs_real脚本
脚本内容如下:
#!/bin/bash
#description : start realserver
VIP=192.168.47.200
/etc/rc.d/init.d/functions
case "$1" in
start)
echo "start LVS of REALServer"
/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce
echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore
echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce
;;
stop)
/sbin/ifconfig lo:0 down
echo "close LVS Directorserver"
echo "0" >/proc/sys/net/ipv4/conf/lo/arp_ignore
echo "0" >/proc/sys/net/ipv4/conf/lo/arp_announce
echo "0" >/proc/sys/net/ipv4/conf/all/arp_ignore
echo "0" >/proc/sys/net/ipv4/conf/all/arp_announce
;;
*)
echo "Usage: $0 {start|stop}"
exit 1
esac

LVS1和LVS2的配置如下:
LVS1:
#!/bin/bash
#description : start realserver
VIP=192.168.47.200
/etc/rc.d/init.d/functions
case "$1" in
start)
echo "start LVS of REALServer"
/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce
echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore
echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce
;;
stop)
/sbin/ifconfig lo:0 down
echo "close LVS Directorserver"
echo "0" >/proc/sys/net/ipv4/conf/lo/arp_ignore
echo "0" >/proc/sys/net/ipv4/conf/lo/arp_announce
echo "0" >/proc/sys/net/ipv4/conf/all/arp_ignore
echo "0" >/proc/sys/net/ipv4/conf/all/arp_announce
;;
*)
echo "Usage: $0 {start|stop}"
exit 1

}

配置完成后可以PING通虚拟IP地址:192.168.47.200
但是无法浏览到真实服务器上的网页
而且在LVS1上使用ipvsadm命令只出现以下内容

Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.47.200:http wlc persistent 60

请问此问题如何解决,烦请告之一下谢谢.
