Linux2.6.9-22.EL LVS/DR 问题

Directorserver配置脚本如下:
#!/bin/sh

#Start LVS of Directorserver, John Yang
VIP=192.168.0.100 (virtual ip)

RIP1=192.168.0.197 (realserver)
RIP2=192.168.0.190

GW=192.168.0.1
. /etc/rc.d/init.d/functions
case "$1" in
start)

echo " start LVS of DirectorServer "
echo "0" > /proc/sys/net/ipv4/ip_forward

echo "1" > /proc/sys/net/ipv4/conf/all/send_redirects
echo "1" > /proc/sys/net/ipv4/conf/default/send_redirects
echo "1" > /proc/sys/net/ipv4/conf/eth0/send_redirects

# Set the Virtual IP Address
/sbin/ifconfig eth0:0 $VIP broadcast $VIP netmask 255.255.255.255 up
/sbin/route add -host $VIP dev eth0:0

# Clear IPVS table
/sbin/ipvsadm -C

#set LVS
/sbin/ipvsadm -A -t $VIP:5222 -s rr
/sbin/ipvsadm -a -t $VIP:5222 -r $RIP1:5222 -g
/sbin/ipvsadm -a -t $VIP:5222 -r $RIP2:5222 -g

#Run LVS
/sbin/ipvsadm

;;
stop)
echo "close LVS Directorserver"
/sbin/ipvsadm -C

;;
*)
echo "Usage: $0 {start|stop}"
exit 1
esac

realserver配置脚本如下：
#!/bin/bash
#description : start realserver
#create in 20060812 by John Yang

VIP=192.168.0.100

echo "0" > /proc/sys/net/ipv4/ip_forward
/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
/sbin/route add -host $VIP dev lo:0

/sbin/ifconfig lo:0

/bin/netstat -rn

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
echo "0" > /proc/sys/net/ipv4/conf/lo/rp_filter

/sbin/sysctl -p

现在的问题是，我用的Linux2.6.9-22.EL的内核，realserver已经做了arp_ignore,arp_announce,rp_filter, director server也设置了send_redirects，当客户端用tcp连接虚拟IP的时候，用/sbin/ipvsadmin -lnc 看到应经转到realserver上了，
可是realserver确实没收到tcp包，请问下，是不是还是realserver arp的问题，应该如何处理？谢谢！
