Rafal Wisniewski manages a good-sized mixed network in a large professional studio. Here are his experiences for ADSL sharing with the simple services included in version 10.2 of Mac OS X. Here is what he writes:
"Jaguar surprises me more and more. Intrigued by the questions of some readers on the Macitynet Forum, I made the most in-depth tests today with the connection / sharing of an ADSL modem. The network was as follows: a G4, a Ti, a PC and an Alcatel modem, all connected to a network switch. Here are two possible configurations
1. On the G4 I configure Internet access, PPPoE (login, password), DNS of the provider, active the ADSL connection, then also active Internet sharing. And here a wonderful thing happens (the TCP / IP part is no longer editable, as some friends have reported, as far as the LAN is concerned but only for PPP, and it would seem that the LAN does not work, but it does not matter), on G4 not only IP forwarding (router service) is activated, but also the DHCP server ( not editable, at least I still haven't found out how you can edit it, even this does not matter at the moment), which provides all the other computers on the network with both the right IP, and subnetmask, and also provider DNS.
So on Ti, under the item Integrated Ethernet it was enough to set DHCP, and I was already on the internet, on pc (win98) it was necessary to restart, after setting here also only "get the IP number automatically" and also win98 traveled on the internet. It is absolutely a very easy operation (it took 5 minutes to have all the computers on the network of networks).
The only drawback of this configuration, that you do not have control of the IPs that are assigned (as long as you edit some configuration files – I will investigate later), which is forced to adapt the peripherals that need a static IP to the numbering predefined by Jaguar 192.168 .1.x.
2. Suppose that our computers are already configured in the home network (with IP 10.10.0.x), without Internet access, perhaps adding an epson printer connected to a printserver also with its static IP, and that this type of configuration (manual) we like it and we don't want to change it. Computers do not have any ip indicated under the heading router (pc gateway), because it was not needed. We get the ADSL modem. Let's connect it to the network switch (hub). On our G4 (which acts as a router) we activate a new port (Network Active Ports) on a Built-in Ethernet basis, for example calling it 'Internet', and making sure that in the list of ports it is located above (IMPORTANT) 'Integrated Ethernet' ( to mean the one already configured for the LAN). In the 'Internet' port we configure PPPoE (login, passwd), TCP / IP (PPP Server), DNS of the provider. In the 'Integrated Ethernet' port we insert the router's IP (in this case corresponding to the LAN IP of this computer – he will be the router), and also the provider's DNS. On other clients the only thing we need to add to our current configuration are the G4 IP LAN under the heading router, gateway (pc), and the usual DNS of the provider, on the pc restart and the game is done. We are all of them on the internet. Even here no more than 5-10 minutes.
