Why are some file names in red type and others in black and some of the faster speeds in blue and others in black? Silly question I know....but why?

The names in red are people who are behind firewalls that you will have virtually no chance of connecting with.
The speeds in blue are speeds actually measured, versus what they set in their configuration menu.

Ahhh...I see. Thanks. But I thought a firewall could be configured to share files on P2P.
