第一步：
配置cnc接口：
interface GigabitEthernet5/1
ip address 60.10.135.11 255.255.255.224
ip nat outside
配置tel接口：
interface GigabitEthernet5/9
ip address 219.148.157.22 255.255.255.252
ip nat outside
配置内网接口：
interface GigabitEthernet5/2
ip address 192.168.0.1 255.255.255.0
ip nat inside
第二步：配置accelist-list
access-list 100 permit ip 192.168.0.0 0.0.0.255 any
第三步：分别配置cnc和tel的地址池
ip nat pool pool2 60.10.135.11 60.10.135.11 netmask 255.255.255.224
ip nat pool pool1 219.148.157.22 219.148.157.22 netmask 255.255.255.252
第四步：配置两个route-map
route-map isp2 permit 10
match ip address 100
match interface GigabitEthernet5/1
!
route-map isp1 permit 10
match ip address 100
match interface GigabitEthernet5/9
第五步：配置两个nat
ip nat inside source route-map isp1 pool pool1 overload
ip nat inside source route-map isp2 pool pool2 overload
第六步：配置路由
缺省从电信走：ip route 0.0.0.0 0.0.0.0 219.148.157.21
目的地址是网通的走网通，例如
p route 202.99.168.0 255.255.248.0 60.10.135.1
将全国的网通地址段全部添加上即可完成。唉，魂牵梦绕的她终于走到了我跟前。
