关于 lvs/tun 再实际部署中的问题

Submitted by professionalzt on 周四, 2012-05-31 07:33

这两天再部署 lvs-tun 遇到一个问题, 经多番 百度 google 无果，无奈之下跑来向基地请求帮助. (话说我再内网做测试的时候是完全没有问题的，不同网段也没问题!!)
还请为小弟解惑..

问题描述:
客户端请求发送到 lvs-tun load balance server , ( 正常 )
lvs-tun load balance server 讲请求调度到 Realserver, (正常)
Realserver 不做回应. (不正常)

lvs-tun load balance server:
VIP: 98.126.175.x1 (eth0:0)
IP: 98.126.175.x2 (eth0)

ifconfig eth0:0 $VIP netmask 255.255.255.255 broadcast $VIP up
route add -host $VIP dev eth0:0

ipvsadm -A -t 98.126.172.x1 -s rr
ipvsadm -a -t 98.126.172.x1 -r 124.115.16.x -i

RealServer (linux)
IP: 124.115.16.x (eth0)
Tunl0: 98.126.175.x1 (tunl0)

ifconfig tunl0 $VIP netmask 255.255.255.255 broadcast $VIP up
route add -host $VIP dev tunl0

echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore
echo "2" > /proc/sys/net/ipv4/conf/all/arp_annouse
echo "1" > /proc/sys/net/ipv4/conf/tunl0/arp_ignore
echo "2" > /proc/sys/net/ipv4/conf/tunl0/arp_annouse
echo "0" > /proc/sys/net/ipv4/conf/tunl0/rp_filter

根据追踪观察所获信息:

lvs load balance server: 98.126.143.148 (CUSTOMER.VPLS.net)
VIP: 98.126.143.139 (CUSTOMER.vpls.net)

realServer: 124.115.15.x
tunl0: 98.126.143.139(CUSTOMER.vpls.net)

------------------------------------------------------------------
客户端: 124.115.15.32(同一机房)
客户端: 223.199.183.60(在家里拨号的 adsl IP)

问题描述: 再同一机房内是访问VIP是可以正常调度到 RealServer , 并且可以呈现网页.
在家里拨号的 adsl IP 访问VIP 也是可以正常调度到 RealServer, 但是RealServer 没有将应该传送的数据 转发给 223.199.183.60

LVS-TUN其实也不能用于全部跨网环境。。。

real-server回应client请求包时，到了IDC的路由器上，其到看到VIP的mac是伪造（或其他什么原因？），IDC的路由器是不会转发这个封包！！

除非real-server和vip是同一个网段的！！
