How do I connect the NAT server on the AR router to two uplinks
A Huawei AR router provides dual egresses of the NAT server. The web server uses internal IP address and port 8080. The IP address of GE2/0/0 (outbound interface) on the router is, and the IP address of GE3/0/0 is The configuration is as follows: 1. Assign IP addresses to interfaces on the router. [Huawei] interface Ethernet0/0/0 [Huawei-Ethernet0/0/0] ip address 24 [Huawei-Ethernet0/0/0] quit [Huawei] interface GigabitEthernet2/0/0 [Huawei-GigabitEthernet2/0/0] ip address 24 [Huawei-GigabitEthernet2/0/0] quit [Huawei] interface GigabitEthernet3/0/0 [Huawei-GigabitEthernet3/0/0] ip address 24 [Huawei-GigabitEthernet3/0/0] quit 2. Configure the NAT server and outbound NAT in Easy IP mode on GE2/0/0 and GE3/0/0. [Huawei] acl number 2000 [Huawei-acl-basic-2000] rule 5 permit source [Huawei-acl-basic-2000] quit [Huawei] interface GigabitEthernet2/0/0 [Huawei-GigabitEthernet2/0/0] nat server protocol tcp global www inside 8080 [Huawei-GigabitEthernet2/0/0] quit [Huawei] interface GigabitEthernet3/0/0 [Huawei-GigabitEthernet3/0/0] nat server protocol tcp global www inside 8080 [Huawei-GigabitEthernet3/0/0] nat outbound 2000 [Huawei-GigabitEthernet3/0/0] quit
