I have a customer running ROS 5.19 that has been working fine. Today he has a strange problem. His RB connects to our tower fine. I can winbox to his cpe. I can see him in the arp list with a ip address. I can't ping him from winbox by ip or mac.

He can ping the gateway 192.168.88.1 but not the wlan address. we have re-programed the cpe but nothing seems to help.



What can be going on and how do we fix it? It seams like a firewall / nat but that is set up correct like it always has been and other customers with same nat rule work fine.

no ideas?

reset to default?

have reset several times still does not work.
