How do I configure the AR router to map multiple public IP addresses to private IP addresses of internal servers

1

A Huawei AR router can use NAT to configure the mapping between public IP addresses and internal IP addresses.
1. Configure the mapping between the public network address and internal network address of the same network segment on the same interface.
[Huawei] interface GigabitEthernet2/0/0
[Huawei-GigabitEthernet2/0/0] nat server protocol tcp global 202.10.1.3 www inside 192.168.0.100 8080
[Huawei-GigabitEthernet2/0/0] nat server protocol tcp global 202.10.1.5 www inside 192.168.0.100 8090
[Huawei-GigabitEthernet2/0/0] quit

2. Configure the mapping between addresses of different segments and internal network address on different interfaces.
[Huawei] interface GigabitEthernet2/0/0
[Huawei-GigabitEthernet2/0/0] nat server protocol tcp global 201.10.1.3 www inside 192.168.0.100 8080
[Huawei-GigabitEthernet2/0/0] quit
[Huawei] interface GigabitEthernet3/0/0
[Huawei-GigabitEthernet3/0/0] nat server protocol tcp global 202.20.1.5 www inside 192.168.0.100 8080
[Huawei-GigabitEthernet3/0/0] quit

How do I configure the AR router to map multiple internal IP addresses to external IP addresses using Easy IP
A Huawei AR router can use Easy IP to implement mapping between internal IP addresses and public IP addresses. Internal users access the Internet by performing Easy IP on GE0/0/1.The configuration is as follows: 1.Configure an ACL rule and configure NAT on the internal network address segment 192.168.0.0/24 . [Huawei] acl 2000 [Huawei-acl-basic-2000] rule 5 permit source 192.168.0.0 0.0.0.255 [Huawei-acl-basic-2000] quit 2. Assign IP addresses to interfaces on the router. [Huawei] interface ethernet0/0/1 [Huawei-Ethernet0/0/1] ip address 192.168.0.1 24 [Huawei-Ethernet0/0/1] quit [Huawei] interface gigabitethernet 3/0/0 [Huawei-GigabitEthernet3/0/0] ip address 200.100.1.2 24 [Huawei-GigabitEthernet3/0/0] quit 3. Configure outbound NAT in Easy IP mode on the outbound interface. [Huawei] interface gigabitethernet 0/0/1 [Huawei-GigabitEthernet0/0/1] nat outbound 2000 [Huawei-GigabitEthernet0/0/1] quit

How do I configure the AR router to map multiple internal IP addresses to external IP addresses using a NAT address pool
A Huawei AR router can use the NAT address pool to implement mapping between internal IP addresses and public IP addresses in the public address pool. The configuration is as follows: 1. Configure a NAT address pool on the router. [Huawei] nat address-group 1 202.169.10.100 202.169.10.200 2. Configure an ACL rule to permit the internal address segment that allows NAT translation. [Huawei] acl 2000 [Huawei-acl-basic-2000] rule 5 permit source 192.168.20.0 0.0.0.255 [Huawei-acl-basic-2000] quit 3. Associate outbound NAT with an address pool on an outbound interface [Huawei] interface gigabitethernet 3/0/0 [Huawei-GigabitEthernet3/0/0] ip address 202.169.10.1 24 [Huawei-GigabitEthernet3/0/0] nat outbound 2000 address-group 1 [Huawei-GigabitEthernet3/0/0] quit

An internal user cannot access the internal server through the public address
An intranet user cannot use a public address to access an intranet server. Use the following method: 1. Check whether services on the intranet NAT server are running properly. 2. Check whether the NAT server is configured correctly. 3. Check the connection between the external host and NAT server and the configurations of the connected interfaces. 4. Check that the intranet NAT server is configured with the correct gateway address or route.

Whether the public IP address and private IP address can be the same in server mapping mode on the USG6000 series
The public IP address and private IP address configured for NAT Server on the USG6000 series cannot be the same.
