Checking Whether Outbound NAT Is Configured on the Public Network Interface

Procedure

• Check whether outbound NAT is configured on the public network interface. If not, enter the interface view and configure outbound NAT.

  <Huawei> display nat outbound 
   NAT Outbound Information:

   GigabitEthernet0/0/0         2000                        1.1.1.1    easyip     
   GigabitEthernet0/0/1         3000                              1       pat

    Total : 2                                                                     

  • If there are multiple public network interfaces, configure outbound NAT on all interfaces that provide Internet access to implement NAT for packets.

    Configure the AR router to implement NAT for hosts on the network segment 192.168.0.0/24 using the IP address of GigabitEthernet0/0/0.

    <Huawei> system-view 
    [Huawei] acl 2000 
    [Huawei-acl-basic-2000] rule permit source 192.168.0.0 0.0.0.255 
    [Huawei-acl-basic-2000] quit
    [Huawei] interface GigabitEthernet 0/0/0 
    [Huawei-GigabitEthernet0/0/0] nat outbound 2000
    

    

    If the PPPoE network access mode is used, configure outbound NAT on the dialer interface associated with the public network interface.
