Ok, so i have linux distro Smoothwall Express (at least i think it's linux...). Anyways, i'm trying to make a physical firebox with two laptops, one is the firebox and the other is my working computer. so i installed smoothwall on my older laptop that is the firebox. the only problem is, i don't have TWO ethernet ports on this laptop, so i can't do it, right?

well, i'm thiking here, my idea is to set up my wireless router, then get my smoothwall to connect directly to it wirelessly for internet, then have my regular computer connected through the firebox to the internet. is there a way i can do this?
