How to implement port mapping on an AR router

Run the port-mapping command on an AR router to configure port mapping based on basic ACLs (number 2000 to 2999). Port mapping is implemented after packets match an ACL rule. To filter packets based on the ACLs, port mapping tries to match the destination IP addresses in the packets with the IP addresses defined in the basic ACL rules.
Example:
# Set the mapping port of the HTTP service to 10. If packets comply with the rules defined in the ACL 2000, the mapping relationship takes effect.
system-view
[Huawei] acl 2000
[Huawei-acl-basic-2000] rule permit
[Huawei-acl-basic-2000] quit
[Huawei] port-mapping http port 10 acl 2000
