When you create an exception or open a port[url="mshelp://windows/?id=8800062b-5df3-4655-adba-b209821d6185#gtmt_port_def"][/url] in a firewall, you allow a particular program to send information to or from your computer through the firewall. Allowing a program to communicate through a firewall (sometimes called unblocking) is like opening a tiny door in the firewall.
Each time you create an exception or open a port for a program to communicate through a firewall, your computer becomes a bit less secure. The more exceptions or open ports your firewall has, the more opportunities there are for hackers or malicious software to use one of those openings to spread a worm, access your files, or use your computer to spread malicious software to others.
It's generally safer to create a program exception than to open a port. If you open a port, it stays open until you close it, whether or not a program is using it. If you create an exception, the "door" is open only when needed for a particular communication.
I'm bored so I decided to make a police chase movie with wrecks and crashes also we need Paramedics and Highways Agency actors. TC members are welcome.
And.
I can't make a server because it wants me to port forward and my dad or anyone will get mad because port forwarding will crash the internet, so someone will have to host their server.
Oh and actually we need traffic for the movie as well.
