about apps that communicate with themselves using ports

Hi all

I have a question about some applications that communicate with
themselves (or with other modules that are part of the same
installation and on the same machine) through network ports. So in
other words the app sends data to a port on the machine that it
resides on, and another part of the app listens on that port and picks
up the data.

Examples of apps doing this include a Python editor, JGroups, etc

My question pertains to a situation where the machine also has a
software firewall running on it.

The question is, are there any cases where this type of communication
does not go through the firewall?

Thanks in advance,

Sure. Those cases where you have removed the firewall. On a properly
configured system you most likely don't need it anyway.
