If you're going to run your computer without a firewall, make sure you keep your computer up to date with all the latest O.S. patches. A virus scanner cannot detect exploits run against your computer.
What type of firewall are you running?
Assuming you have a router/firewall.(d-link, netgear, linksys)...
Most consumer routers use stateful filtering, meaning they will only allow Internet traffic into your network, which originated in your network (ie.. response to a web page request). Most likely what's happening is that the connection requests from your friend are being dropped at the router since they didn't originate in your internal network. In order for him to be able to connect, you will need to open the specific port your friend needs to connect to from the outside interface, to the IP address of your internal server(not sure what is is for BF)
