Basic UDP access is available.
The client was unable to send fragmented UDP traffic. The most likely cause is an error in your network’s firewall configuration or NAT.
The maximum packet successfully sent was 1476 bytes of payload.
The client was able to receive fragmented UDP traffic.
Is this normal?
btw does MikroTik provide support after 30 days?
