    Hi there,

    I am soon to have 2 separate internet connections in my home (one cable and one adsl). What I am wondering is if my 2 main macs can use separate internet connections and still have a local LAN together.

    I would assume I need 2 ethernet on each system. My only option then would be to use airport and ethernet on my mini then add an ether. PCI card to my Sawtooth G4.

    As far as I know a router can only use 1 connection. Any advice or help is greatly appreciated.

    Sure, that's entirely possible, except you'll need two routers. Each Mac will sit behind the separate router, and have that router as its gateway. I would make each of these subnets different, such as 192.168.1.x for one and 192.168.2.x for the other. This is just for ease of knowing each different subnet, and will not affect connectivity in any way.

    You will then use a separate switch, or another router/switch combo, to have an internal network. Assign each Mac an IP on a different subnet than the Internet side. For example, if your Internet subnets are 192.168.x.x, then choose something like 10.x.x.x or 172.21.x.x. You can use a subnet mask of for each of those with no concern.

    What you don't want to do is plug both Macs into each router. Keep the Internet side of each Mac separate.
