7）出口配置动态路由协议让全网互通，配置nat让公司内部可以上网

8）在出口路由器和分公司路由器上走ppp协议实现全网互通
R1配置
En
Conf t
Username r2 password cisco
Int s0/0/0
Encapsulation ppp
Ppp authentication chap
end
write
R2配置
En
Conf t
Username r1 password cisco
Int s0/0/0
Encapsulation ppp
Ppp authentication chap
End
Conf t
interface Loopback0
ip address 4.4.4.4 255.255.255.255
No shut
interface Serial0/0/0
Clock rate 64000
ip address 113.105.134.86 255.255.255.0
No shut
interface FastEthernet0/0
ip address 218.23.88.1 255.255.255.0
duplex auto
speed auto
No shut
Write
9）将公司内部接入层交换机端口加入到对应的vlan，把电脑连接上交换机，整个项目完成！
实例：将iou3当做人事办公室，配置如下
Iou3上
En
Conf t
Int rang f0/3-24
Sw mo acc
Sw acc vlan 10
End
Write
10）发布web服务器出去让外网用户能够访问到公司利用web服务器发布的消息
在出口路由器上配置
En
Conf t
Ip nat inside source static tcp 192.168.2.5 80 113.105.134.85 80
Access-list 1 permit 192.168.2.0 0.0.0.255
End
Write
验证结果如下：
11）配置acl8.0网段的用户只能访问公司ftp服务器，各vlan部分之间不能互访,但是网管1点段可以访问任意内外网方便管理，公司ftp是可以让任何人都访问到使用，web服务器除了8.0的用户其他用户都可以访问得到，公司除了8.0网段的用户，其他用户都可以访问web服务器和ftp服务器以及外网，只是不能访问到其他内部部门网段而已。
备注：真实环境和iou都是两边路由器配置一模一样，在pt中因为没有做hsrp，所以在
调用acl时候，sw1分别只调用int vlan30 -40 而在sw2上只调用50-80
access-list 100 deny ip 192.168.8.0 0.0.0.255 192.168.2.5 0.0.0.0

Int vlan 20到80之间分别调用acl命令如下;因为这里需要vlan10和所有人通讯，服务器是管理员在管理，并且所有人都可以访问它，所以并没有写入acl，实际上也是这样，当然你可以精确到哪个ip地址，写法完全一样
ip access-group 101 in
ip access-group 102 in
ip access-group 103 in
ip access-group 104 in
