Re: Aruba RAP contact to public IP VMC AOS8.3 problem need help

We also have one PC in the same network with our RAP,

If we do not power RAP, we can access the VMC public IP 47.104.193.111 bye WEB and SSH (1:1 nat to 172.31.4.51)

 

but If we power up our RAP, and boot finished, we found we still can ping 47.104.193.111 OK, but we CAN NOT access by WEB and SSH!!!

 

anybody can see all of the information and help us ?
