Airport network problem

[mrfrost]

Hey,

I have 2 comps set up to use my cable connection through airport.
Both of my comps have internal IP adresses now (10.0.1.2 and 10.0.1.3)
The airport base station has 10.0.1.1 and is connected to the cable modem.
My problem is that since both my comps have internal IP adresses I cannot serve anything anymore. Is there a way to make one of my computers have the external IP adress instead ?

using the airport admin utility, you can choose for the base station to act as just a hub as opposed to a router, which is what it's set at by default.

If your ISP won't let you have more than one IP, you can use port mapping in the admin utility to pass traffic on those ports to a specific comp on your network, as well.

See this article (http://docs.info.apple.com/article.html?artnum=120061). There's a pdf to download, but it talks about port mapping.
