c2800#conf t
c2800(config)#enable secret aaa123456
配置打开telnet功能，登陆密码设置为123456
c2800(config)#line vty 0 4
c2800(config-line)#password 123456
c2800(config-line)#login
c2800(config-line)#exit
配置路由器接口地址及NAT接口角色：
c2800(config)#interface serial 1/1 －－本例中以serial 1/1为连接服务商的接口
c2800(config-if)#ip add 219.250.73.194 255.255.255.240
c2800(config-if)#no shut
c2800(config-if)#ip nat outside
c2800(config-if)#interface serial 1/0 －－本例中以serial 1/0为连接内网的接口
c2800(config-if)#ip add 192.168.100.3 255.255.255.0
c2800(config-if)#no shut
c2800(config-if)#ip nat inside
c2800(config-if)#exit
c2800(config)#ip route 0.0.0.0 0.0.0.0 192.168.100.1 －－定义一条默认路由到达内网，下一跳为：192.168.100.1
定义地址池：
c2800(config)#ip nat pool poolname 219.250.73.200 219.250.73.200 netmask 255.255.255.240
定义允许的流量：
c2800(config)#access-list 10 permit 192.168.102.0 0.0.0.255
c2800(config)#access-list 10 permit 192.168.103.0 0.0.0.255
c2800(config)#access-list 10 permit 192.168.104.0 0.0.0.255
c2800(config)#access-list 10 permit 192.168.105.0 0.0.0.255
c2800(config)#access-list 10 permit 192.168.106.0 0.0.0.255
c2800(config)#access-list 10 permit 192.168.107.0 0.0.0.255
配置PAT:
c2800(config)#c2800(config)#ip nat inside source list 10 pool poolname overload
c2800(config)#snmp-server community aaa ro 配置本路由器的只读字串为aaa
c2800(config)#

ip route 0.0.0.0 0.0.0.0 219.250.73.193 //出街的默认路由
//以上是配置各内网的网关,注意.路由器下带的交换机必须配置vlan102~107，对应enc dot1q [vlan id]来配置并且与路由器连接的是trunk口.封装IEEE 802.1q协议
router(config)#ena sec aaa123456
line vty 0 4
pass 123456
logi
//以上是telnet
另外声明一点.SNMP管理我不会配.!!

ip nat in s li 1 int fa 0/0 over
这个地方不大对，楼主要的是地址池
access-list 100 permit 192.168.100.0 0.0.0.255 any
access-list 100 permit 192.168.102.0 0.0.0.255 any
access-list 100 permit 192.168.103.0 0.0.0.255 any
access-list 100 permit 192.168.104.0 0.0.0.255 any
access-list 100 permit 192.168.105.0 0.0.0.255 any
ip nat pool 100 219.250.73.200 netmask 255.255.255.0
ip nat inside srouce list 100 pool 100 overload
