The addresses starting with 192.168 are designated as LAN addresses. They cannot be resolved outside the local network. The router has to be told to forward connections on the Appleshare/IP port to the server machine. For example, all the machines I have at home are behind a router. They have numbers of the form 192.168.0.x. I've set up my router to forward different port requests to different machines. The Linux box is 192.168.0.254, and it gets Web requests (port 80), ftp requests (port 80), mail (port 21) and ssh (port 22) and a few others. The desktop G4 gets Appleshare (port 548) and a few others. Only one machine at a time can serve a particular port and LAN machines attached to particular services should have static addresses on the LAN. It works like this... The router connects your local LAN to the Internet. From the Internet side, your whole LAN looks like one machine with one IP address. The router takes traffic from your LAN and directs it out to the wide world through that one address and takes traffic from the wide world and decides which machine on the LAN side should get which packet. Until you tell your router where to send particular packets, they'll just be thrown away. | The next meeting of the Louisville Computer Society will | be January 27.
