Does "internal" really apply to a single computer? There is only what's external to it, that is the rest of the lan and beyond that it has to be protected from.
think at the firewall as a door. on a single computer, as on a house, the external is the door that opens to the network, the internal is the house, that is your computer. if your computer is not otherwise connected, the firewall is only useful to protect you from bad configuration, because any non used port is "closed". An open port is a port some application read and his security is up to the application, a closed port is either a port that nobody reads, or one that the firewall is blocking. there is a discussion about is it necessary to have a firewall even for unused ports, because any port is read at least a some level, else nothing will be transmitted to applications, but I have no idea on this. jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
