You (or your bro) has to forward UDP ports 47776 - 47087 to your computer (assuming you have a router / multiple computers connected to the internet thru one broadband modem)
If you have only one computer connected to the modem, contact your ISP about it. (They would be more likely to have control over it)
If one of you live in a college/university you'd have to talk to the proper people having authority over the computer networks to get it working. Show them the UDP port numbers above.
Shut off all firewalls on both systems, including the windows firewall.
www.portforward.com is a place to learn how to forward ports on a home router.
