I have remote site with above design. "login" is gray out in CAA. I run tcpdump on NAS, and I saw packets are hitting eth1 on NAS. In NAM, I got this error message "Unable to process out-of-band login request from [00:00:00:00:00:00 ## 10.111.18.3] Administrator. Cause: MAC address of 10.111.18.3 not found.".
any idea would be very appreciated. if you need more information, please let me know. it's kind of urgent.
