In the same simulation as the previous wifi broadcast question, I am
using the broadcast address (255.255.255.255) as the destination;
however, the trace shows that the destination is not 255.255.255.255,
but rather 10.1.3.255. Is there something else I need to set to have
it truly broadcast to 255.255.255.255?
