blocking udp port 0

RouterOS General
1

I have a customer that is able to exceed their queue limitation by sending and receiving data on udp port 0. I have tried to mangle this and block it in firewall without success?

Anybody give me pointers on how to queue this traffic?


Thanks,

Wayne

/ip firewall filter add chain=forward protocol=udp dst-port=0 action=drop
