Hi, I found this on MacSlash the other day. If you are running OSX, this seems pretty applicable to your situation. If you're not running OSX, you might consider it of just skip all this:
The link to the thread first and then the quoted part- http://macslash.org/article.pl?sid=03/06/18/1410207&mode=thread Quote:� "I'll need to add a second ethernet port to do so." You don't need a second ethernet port -- you can have built-in ethernet act as if it was two ports, and have the iMac do Network Address Translation between them. For that go to System Preferences > Network > Show: Network Port Configurations. Click� "New", select "Port: Built-in Ethernet" and give it any name (other than "Built-in Ethernet", which is already taken). Click OK. Presto, you have a new (virtual) interface in the "Show:" menu, which works just as if you had added a real one. You can configure it in Network prefs or via unix tools (ifconfig, ipfw, natd, etc.) Alternatively, if Jaguar's built-in NAT is good enough for you, do all this with a single click by going to System Preferences > Sharing > Internet, select "Share the connection on Built-in Ethernet" and click Start. This way the virtual interface does not show in the GUI, but you see it in Terminal: [localhost:~] fz% ifconfig en0 inet en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,M ULTICAST> mtu 1500 � � � � inet 10.0.0.146 netmask 0xfffffe00 broadcast 10.0.0.255 � � � � inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255 Some people say that splitting a single interface like this is "less secure", but I've not seen any *concrete* confirmation of that. I have an old beige 7300 with 2 Ethernet cards, running SuSE PPC, that I set up for the purpose in the OS 9 days, but given the simplicity of the above, I hardly ever turn it on for that purpose now. > The wife-Mac will have to use the iMac internal > modem? > Thanks all, > JCT __________________________________ Do you Yahoo!?
