I imagine most groups will ask this question at some point, so here it is. Use
findRouteEntry from routetable.c first to find your interface number, then use
that number in findInterfaceIP from mtu.c to get the source address. As for
the port I believe it is your choice. This is not necessarily the only
solution, so if you have it working another way (other than hardcoding), there
is no need to change it.

I understand when we process the UDP packet, we can get the source IP and port
from the IP header, but what about when we send the UDP packet? Do you know
what method to call to get those information?
