Consider the McAfee firewall on your computer as a last resort between the
data on your computer and the data flowing in and out of your network.
Essentially, that's what it is. If your neighbor ties into your wireless
network (with or without your permission) then the last resort would depend
on whether he/she has a firewall installed also.
The internet router acts like a firewall in some sense. Just in the sense
that if you don't have ports configured to be forwarded, no incoming data
will get through it (or shouldn't) unless you initiate the connection. If,
however, you have a port forwarded to your computer (essentially telling the
router that any data coming in on this port goes to this IP address), then
any incoming data will reach your computer. It's up to your software
firewall (McAfee in this case) to determine if the data is ok or malicious.
If you don't have a firewall, then any data coming in on the forwarded ports
will have free reign of your computer.
Please understand that when I refer to "Data" in my above statements, I'm
including attempts to log into your computer, viruses, spyware, pictures,
text, and whatever else comes in on a packet.
