For example, if you're surfing this website right now, I KNOW you're connecting to the destination port of 80. However, what port your computer is
using to connect to this site (source port) could be ANYTHING!
That's pretty accurate. The port the server is listening for connections on would be 80, or 443 if https. Your computer isn't using port 80 to
connect to the server, port 80 is for incoming web traffic. In most cases your computer would be using a port in and above the 1024 range or way
Ports in the low ranges like 80 and such are reserved for specific applications, while the higher ports are essentially a free for all.
As well keep in mind we talking about open and closed ports.....
A port is only "open" while in use. People talking about closing ports are really talking about blocking them, as msot of those ports are actually
closed anyways, you are just severely limiting the options for the apps to use.
I use bittorrent, like many people, to download custom android roms, linux distros, etc etc...
I watch my ports and sometimes the range in use would be 1200, other times, 40.000, it's very subjective and really unless you know what you are
doing, you should be weary of blocking ports, and for gods sake don't block any below 1024.
