-I'm using windows xp.
-I don't think i have any firewalls but the windows Internet Connection Firewall and i have checked File sharing as an exception.
-I have 240 MB of Ram
-76 GB HDD
-Cable internet or LAN whatever they call it, but its no that fast
-I don't have a modem, I have a Network card: Realtek RTL8139 Family PCI Fast Ethernet NIC
-Trying to connect from home
-Java 1.5.0_01

I've already been to this firewall setup page before, and I did what it says, and it was useless

I did the test and it was a success
