hifirst and hilast represent the range of ports that we should be using
for outbound connections.  If you need more ephemeral ports, change .first
and .last to equal the corresponding hi values.

For more background, read one of Stevens's books.  (This is mentioned in
UNIX network programming volume 1, I'd assume the tcp books cover it as
well.)
