Method used to configure the mapping of one public IP address to multiple private servers on the USG2000 and USG5000

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

The mapping between IP addresses can be configured only when there are multiple public IP addresses.

The public IP address and private IP address configured for NAT Server on the USG6000 series cannot be the same.

The U1911/U1960/U1980/U1981 supports multi-network-port work mode to separate the service and management data. In general, the gateways work in single network port mode, and the first two network ports of a gateway work in active/standby mode. In multi-network-port mode, only network port 0 can be used to manage and maintain the device. Other voice gateways do not support multiple IP addresses, and the first two ports work in active/standby mode.
