雙線網路釋出伺服器以及使用者端上網介紹

2020-10-28 09:29:30

  實驗要求:

  1、公司想將自己的伺服器雙線釋出出去。

  2、員工可以存取電信和網通的WEB伺服器。

  設定思路:

  1、事先指明公司和電信網通路由器的NAT的內部和外部埠。設定NAT路由器的預設路由。

  2、實現公網網路互通。

  3、公司設定:

  設定存取控制列表

  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 (允許所有網段通訊)

  設定PAT ip nat inside source list 100 電信wan口 overload

  ipnat inside source list 101 網通wan口 overload

  釋出網站 ip nat inside source static tcp 伺服器私網地址 80 電信公網地址 80

  ip nat inside source static tcp 伺服器私網地址 80 網通公網地址 80

  4.電信和網通設定

  設定存取列表 access-list 1 permit公司內網網段

  設定PAT ip nat inside sourcelist 1 interface FastEthernet0/0 overload

  釋出網站 ip nat inside source statictcp 192.168.5.3 80 192.168.4.100 80

  實驗設定如下:
