R2上做静态路由：
[r2]ip route 192.168.1.0 24 192.168.4.1
[r2]ip route 192.168.2.0 24 192.168.5.1

r2上做访问列表：
[r2]acl 2000
[r2-acl-2000]rule permit source 192.168.3.0
Rule has been added to normal packet-filtering rules
[r2-acl-2000]acl 2001
[r2-acl-2001]rule permit source 192.168.3.0
Rule has been added to normal packet-filtering rules
[r2-acl-2001]inter s0
[r2-Serial0]nat outbound 2000 interface
[r2-Serial0]inter s1
[r2-Serial1]nat outbound 2001 interface
本地虚拟机测试：
