[WYWU]

Hi,

      I use MX100 testing  "1:Many NAT"

info:

server 10.10.154.18 port23

mx100 wan 1.1.1.1/24  (for example) 

public ip 1.1.1.2 

Q1: when i change public port it cannot work??

1.1.1.2:3333 -> 10.10.154.18:23 can work

when i accesss to 1.1.1.2:3333 ,it can  redirect to 10.10.154.18:23

but when i change public port to 4444, nat cannot work:

1.1.1.2:4444 -> 10.10.154.18:23 cannot work

Q2: when i change public IP it cannot work??

1.1.1.2:3333 -> 10.10.154.18:23 can work

when i accesss to 1.1.1.2:3333 ,it can  redirect to 10.10.154.18:23

but when i change public IP to 1.1.1.3, nat cannot work:

1.1.1.3:3333 -> 10.10.154.18:23 cannot work

why????? i think it's a bug, anybody could HELP me??????

It sounds like the existing NAT state is not being flushed correctly.

After making the change and saving it, can you reboot the MX during a maintenance window to see if it takes that change?  MX's are notorious for caching data flows which makes change testing tedious.
