B、定义Access-list 为作NAT准备
access-list 101 permit ip 192.168.0.0 object-group wtnetwork
#内部网络到网通IP网段的Access-list
access-list 104 permit ip 192.168.0.0 255.255.255.0 any
#内部网络到任何IP的Access-list
C、NAT配置
global （outside） 1 interface
#定义NAT ID 1为网通的出口ip
global （teloutside） 4 interface
#定义NAT ID 4为电信的出口ip
nat （inside） 1 access-list 101
#定义符合access-list 101（就是内部到网通IP网段）就转换成NAT ID 1的IP（网通的出口）
nat （inside） 5 access-list 105
#定义符合access-list 101（就是内部到网通IP网段）就转换成NAT ID 1的IP（网通的出口）
注意：nat （inside） 1 access-list 101一定要在nat （inside） 5 access-list 105前面。
D、Route路由配置
#####添加默认路由往电信的网关出去################
route teloutside 0.0.0.0 0.0.0.0 202.99.114.126 1
##################################################
#######添加静态路由往网通IP网段往网通的网关出去######

四、实现效果
目前国内的骨干网分为南、北两张网。南电信北网通，不通运营商之间的通讯都需要到骨干进行数据交换，因此网通的用户访问电信网站很慢而电信用户访问方位网通网站也很慢，因此对大型网络设置双出口可以使不同运营商之间网络访问速度得到改善，本文档是在这一背景下产生的需求。
