DHCP server weird behaviour continously seeing DHCP offer

Sun Sep 18, 2022 1:35 pm

Hi,

MikroTik is sending continuous DHCP offer messages even are successful DHCP allocations.

On Log we can see unsuccessful allocation, my clients are working fine unless ACK is not reaching the server. DCHP request is coming through EOIP tunnel.

Any help or guidance will be greatly appreciated.
