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

Intranet users cannot access the internal server using a domain name, but they can access the internal server using an IP address
Q: Intranet users cannot access the internal server using a domain name, but they can access the internal server using an IP address. A: Ping the domain name and check whether the public IP address can be parsed. If the IP address cannot be correctly parsed, check whether the account password and DNS information are correct. Configure DDNS software on the PC to check whether the IP address can be parsed. If no error is found in the preceding operations, contact the carrier to check the DDNS server. Check whether the DDNS server synchronizes the updated domain name to the DNS server. The causes are as follows: It is used in the scenario where terminals use PPPoE dial-up. The router runs normally when users can access the internal server using IP addresses. DNS resolution is the first step to access a domain name. Because the PPPoE interface dynamically obtains an IP address from a carrier, the DDNS server must send the updated mapping between the domain name and IP address to the DNS server in real time. Check whether the DDNS server synchronizes the updated domain name to the DNS server.
