ipfw is an IP firewall and traffic shaper control program.
The term "me" appears on
ipfw statements like below:
ipfw add 02050 allow tcp from me to any out
I would like to know exactly what "me" means here.
A man page defines "me" as
me: matches any IP address configured on an interface in the system. The address list is evaluated at the time the packet is analysed.
Regarding the phrase "configured ... in the system", which system is it talking about? Is it talking about the local computer that contains the current directory in which the
ipfw command is running, as opposed to a remote computer?
Regarding the phrase "configured on an interface in the system", what does it mean by an "interface"? Examples of interfaces familiar to me are keyboards, mice, and display monitors. However, I do not think that the man page is talking about keyboards, mice, or monitors.
