Genesis: How do I add a route to another network?

[Zac67]

Is that a wireless-only router?? Otherwise connect Amy directly and that's it. Your setup's way too complicated.

I'm not sure if Internet sharing through the iBook works since that iBook only has a NATted connection itself. You don't need ICS, you need simple routing through the iBook.

Thomas' point is very valid. Try this:
- ping iBook (works)
- ping Router (if that fails, the ICS is bad)
- ping some IP outside (if that fails, the iBook's ICS in combination with NAT on the router is bad)
- setup default gateway and DNS as Thomas wrote

Deactivate ICS on the iBook. Is that OS X? From what I found, you've got to activate the IPFORWARDING service.

I suppose you set the correct networks masks - 10.x.x.x is class A by default; you're subnetting it to class C, that's a mask of 255.255.255.0. If Amy's got 255.0.0.0 she won't ever try to talk to the default gateway (=iBook)...
