Issue Description

The client has the following scenario:

He wants to know to configure the dynamic NAT on the AR161 router for the client A to be able to do a videoconference and have access the internet through a single internet connection.

Solution

1. Configure NAT outbound so the user A can access the Internet like below:

Run:

system-view

The system view is displayed.



  • Configure outbound NAT.
    Users can choose one of the following configuration methods based on actual
    situations:


    • Configure outbound NAT with an
      address pool.

      1. Run:
        nat address-group group-index start-address end-address

        A public address pool is configured.


      2. Run:
        interface interface-type interface-number [ .subnumber ]

        The interface view or sub-interface view is displayed.


      3. Run:
        nat outbound acl-number address-group group-index [ no-pat ]

        Outbound NAT that references an
        address pool is configured.



    • Configure Easy IP without an address pool.

      1. Run:
        interface interface-type interface-number [ .subnumber ]

        The interface view or sub-interface view is displayed.


      2. Run:
        nat outbound acl-number [ interface interface-type interface-number [ .subnumber ] ] [ vrrp vrrpid ]

        Easy IP is configured.

  • 2.Configure NAT server so the external users can access the private network like below:


    [Router-GigabitEthernet0/0/0]nat server  global X.X.X.X inside Y.Y.Y.Y


    3. Configure NAT alg so the packets for the application protocol can traverse the public network through NAT like below:

    [Huawei] nat alg sip enable
