My cable modem feeds my built-in ethernet. The PCI ethernet card feeds
a 4 port ethernet hub which connects to my PC and old G3.

That feeds a hub which connects to my other computers. This was the
preferred configuration of some years ago. Only my G5 is connected to
the internet, everything else is fed from the second ethernet card in
the G5. The G5 acts as the router.

Got no router, I'm using the G5 as the router as described in the

system preferences/
internet and network/
sharing/
sharing your internet connection

help file.


"If your computer is connected to the Internet, you can share its
connection with other computers on your local network.
For example, if your computer is connected to the Internet using a DSL
modem and has an AirPort Card installed, you can share the DSL
connection with other AirPort-equipped computers.
On Windows computers, sharing your Internet connection is sometimes
referred to as a "network bridge," or 'bridging your network."

1. Open System Preferences, click Sharing, and then click Internet.
2. Choose a network port from the "Share your connection from" pop-up
menu.
3. Select "Built-in Ethernet" or AirPort depending on which computers
will share your Internet connection.
4. In order to share your Internet connection and allow computers
connected to your Internet connection to browse the web, you also need
to turn on Personal Web Sharing on the Services pane of Sharing
preferences."


What I've just discovered is that this sharing works as long as I
(administrator) am not logged into the gateway G5. If any
non-administrators are logged into the G5, the other computers can
connect to the internet just fine. It's only when I'm logged into the
G5 that the other computers can't connect, very confusing.

Any help appreciated.
