實驗要求:
1、公司想將自己的服務器雙線發布出去。
2、員工可以訪問電信和網通的WEB服務器。
配置思路:
1、事先指明公司和電信網通路由器的NAT的內部和外部端口。配置NAT路由器的默認路由。
2、實現公網網絡互通。
3、公司配置:
配置訪問控制列表
access-list 100 permit ip any 電信非直連網段 (允許電信網段)
access-list100 deny ip any 電信非直連網段 (拒絕電信網段)
access-list 100 permit ip any any (允許所有網段通信)
配置PAT ip nat inside source list 100 電信wan口 overload
ipnat inside source list 101 網通wan口 overload
發布網站 ip nat inside source static tcp 服務器私網地址 80 電信公網地址 80
ip nat inside source static tcp 服務器私網地址 80 網通公網地址 80
4.電信和網通配置
配置訪問列表 access-list 1 permit公司內網網段
配置PAT ip nat inside sourcelist 1 interface FastEthernet0/0 overload
發布網站 ip nat inside source statictcp 192.168.5.3 80 192.168.4.100 80
