Follow-up Comment #8, task #7272 (project lwip):

UDP is meant to send ICMP destination unreachable when there's no pcb. TCP
sends a RST. It doesn't send ICMP.

Strictly you should report ICMP destination unreachable for UDP, but heck,
most machines with firewalls don't anyway. So allowing it to be turned off
doesn't seem that evil.
