LB四层服务器负载实服务器主动访问客户端并隐藏源地址典型配置

某据点组网图简化如下：

要求实服务器能反向主动访问客户端，且源地址变为虚服务的地址。

nqa template tcp t2

 source ip 10.34.5.2

#

server-farm sf3

 probe t2

#

real-server rs17

 ip address 10.34.101.17

 port 7920

 server-farm sf3

 probe t2

#

real-server rs18

 ip address 10.34.101.18

 port 7920

 server-farm sf3

 probe t2

#

virtual-server guoji type tcp

 port 1000

 virtual ip address 10.34.26.11

 default server-farm sf3

 service enable

#

interface Route-Aggregation1.11   //反向流量入接口

 ip address 10.34.5.2 255.255.255.248

 vlan-type dot1q vid 11

interface Route-Aggregation1.10  //反向流量出接口

 ip address 10.34.3.234 255.255.255.252

 nat outbound 3502 address-group 2

 vlan-type dot1q vid 10

#

acl advanced 3502

 rule 1 permit ip source 10.34.101.17 0

 rule 2 permit ip source 10.34.101.18 0

#

nat address-group 2

 port-range 1 999  //不能包含虚服务端口号

address 10.34.26.11 10.34.26.11  //虚服务地址

来回流量都要经过LB，路由及网关上配置略
