Use the ip forward-protocol udp command to specify the protocols and ports the AOS allows when
forwarding broadcast packets. Use the no form of this command to disable a specified protocol or port
from being forwarded.

The ip helper command must be used in conjunction with the ip forward-protocol
command to configure the AOS to forward UDP broadcast packets.
