Evening all,
Am I too paranoid, do I need to enable my firewalls to stay safe?
I have my emac connected to the internet via usb modem.
I share that connection with my ibook via computer to computer network using airport extreme cards.
I'd like to have the firewalls enabled on both machines, but when I try, my ibook will not connect to the internet. Is this possible and or required???

It can't hurt, but it's not entirely required.
The UNIX base of OS X is pretty darn secure already. I don't think you're in any immediate danger.

If you're using broadband, and the modem has it's own router, then you're already covered. If it's dialup... well, it'd be so slow to actually try and hack you that I doubt anybody would bother :D

Thanks mate,
I'm on ISDN and my telstra NT1+2 modem is just a modem, but its on about 20 hrs a day. I am thinking of getting a netgear FWG114p as a hardware firewall so I dont have to rely on the OS X firewalls.
But, I would still like to explore all posibilities first.

Probably best to have the firewall on then...
I'm not 100% sure how the firewall works in OS X, but if your eMac has it's firewall on, then the iBook should be covered by it.

Does anyone know what order the layers work in here?
I assume it's Internet -> Firewall -> Internet Sharing, not Internet -> Internet Sharing -> Firewall

In general -

There is no need to enable the firewall on the iBook.

The eMac in this case is already acting as the firewall / nat / router.
