According to document, "IP directed broadcasts using the User Datagram
Protocol (UDP) will be exploded only if the ip forward-protocol global
configuration command has been used to enable UDP broadcast forwarding
for its destination port, regardless of the setting of the ip
directed-broadcast command.". So what you have done is correct.
