Has anyone had an issue with the ARP table not clearing the MAC address and IP information even after the device has disconnected (failed or replaced). We are using RB433, RB493, or RB2011AHx2 for bandwidth control and/or AP.
When connecting a new customer router with static IP address and/or CPE at a customer location. We cannot get online until we manually go into the ARP table of the Mikrotik on the tower side and remove the IP address with the old mac address. Then the new mac address with the same IP address shows up and internet access is available. Why is the ARP record not going away automatically? It does it on most of my other RouterBoards just having this issue on a couple.
Any ideas?
