NAT doesn‘t work on eNSP

NAT still doesn't work on eNSP (including latest version
I've got the same result as with version
Please see my previous post

Lab 3-2 from "HCNA-HNTD Intermediate Lab Guide v2.1" cannot be done as expected.
eNSP doesn't work correctly after applying NAT command on interface.
[R1-GigabitEthernet0/0/0]nat outbound 3000 address-group 1
[R3-GigabitEthernet0/0/0]nat outbound 2000
and after sending interesting traffic, of course.

Some additional information:
Before applying NAT commands on interfaces
  S1 can ping R1  (ping
  S2 can ping R3  (ping
  Windows Task Manager
    total CPU usage = 45%
    VBoxHeadless.exe CPU usage = 13%
    VBoxHeadless.exe CPU usage = 13%
After applying NAT commands on interfaces and sending interesting traffic
  S1 can't ping R1  (ping
  S2 can't ping R3  (ping
  Windows Task Manager
    total CPU usage = 100%
    VBoxHeadless.exe CPU usage = 50%
    VBoxHeadless.exe CPU usage = 50%

Please fix it.

Thank you.

At least, NAT doesn't work if configured according to Lab 3-2 from "HCNA-HNTD Intermediate Lab Guide v2.1"

Configuration in file nat.rar above is logically the same like in the Lab 3-2
However, I used topo-file that built in eNSP
C:\Program Files\Huawei\eNSP\examples\HCNA2.0 Lab\Part 2\Lab 3-2 Network Address Translation (Unconfigured)

You should apply NAT configuration on interfaces and send interesting traffic
to make sure that NAT doesn't work.
Interesting traffic defined in acl.
I used ping from S1 to R3  (ping
   and ping from S2 to R1  (ping
