By using the ip helper-address command, a router can be
configured to accept a broadcast request for a UDP service
and then forward it as a unicast to a specific IP address,
as . Alternatively, the router can forward these requests
as directed broadcasts to a specific network or subnetwork.

RTA(config-if)#ip helper-address 192.168.1.254
RTA(config-if)#exit
RTA(config)#ip forward-protocol udp 517
RTA(config)#no ip forward-protocol udp 37
RTA(config)#no ip forward-protocol udp 49
RTA(config)#no ip forward-protocol udp 137
RTA(config)#no ip forward-protocol udp 138


so if you will not confgure the ip helper it will not
broadcast the udp packet
