网络拓扑描述：
Director[VIP:192.168.11.199]
Realserver1[RIP:192.168.30.10]
Realserver1[RIP:192.168.30.30]
在终端执行一下命令：
echo "1" >/proc/sys/net/ipv4/ip_forward
/sbin/ipvsadm -A -t 192.168.11.198:80 -s rr
/sbin/ipvsadm -a -t 192.168.11.198:80 -r 192.168.30.10:80 -m -w 100
/sbin/ipvsadm -a -t 192.168.11.198:80 -r 192.168.30.30:80 -m -w 100
执行命令ipvsadm -Lnc
[root@localhost ~]# ipvsadm -Lnc

多次在客户端打开IE或者 telnet 192.168.11.198 80，有以下结果
[root@localhost ~]# ipvsadm -Lnc

请章博士和各位兄弟帮忙！
-------------------------------------------------------------------------------
Director和RealServer1运行在同一台物理机器上，都运行在VMWARE上。
RealServer2跑在另外一台物理机器上，运行在VMWARE上。
后面我在控制台运行了如下命令：
echo "0" >/proc/sys/net/ipv4/conf/all/send_redirects
echo "0" >/proc/sys/net/ipv4/conf/default/send_redirects
echo "0" >/proc/sys/net/ipv4/conf/eth0/send_redirects
如果单独
/sbin/ipvsadm -A -t 192.168.11.198:80 -s rr
/sbin/ipvsadm -a -t 192.168.11.198:80 -r 192.168.30.10:80 -m -w 100
现在在客户端打开网址[url]http://192.168.11.198[/url] 是没问题了，可以访问到RealServer1 192.168.30.10
但是我通过命令
/sbin/ipvsadm -a -t 192.168.11.198:80 -r 192.168.30.30:80 -m -w 100
把RealServer2加上后，还是访问不了RealServer2提供的80服务，比较郁闷！
请教大家!
