I'm not sure which generation of Airport Extreme you have. But for my UFO white Airport Extreme, just launch the Airport Admin Utility. Click on the "Port Mapping". Then "Add" a new item. Apply and restart the Base Station, simple.

Which IP to static IP? Client or the Server?
If you want to fix the IP of your connected Mac, just reserve the IP by specified the MAC address.

I think you need to spend sometime RTFM.
Here's what I found from Apple:
- Airport Support Page.
- How to... page
- and here's the manuals incase you lost it.


tinkerbel, the new one doesn't look like UFO. It looks more like MacMini/ Apple TV.
The older wifi b/g version looks like UFO:


There's many article around explaining the n/g/b networking.

Basically if you use a non-wifi n device with the new wifi n Airport Extreme you will not get the full benefit of the wifi n technology.

Let's say you connect a wifi g iBook to the new Airport Extreme, you will get a wifi g connection at wifi g speed. Do not hope that the new base station will do wonders on a older receiver/client. You might get better signal strength thus slightly better connection speed.

Imagine you driving a Kancil in a "no other cars & no speed limit 5-lane highway". Yes you can go very fast, but your car is limiting how fast you can go.
(no offense to Kancil owner or driver just giving some example, I know some modded Kancil can really go FAST.)

As what I understand, if the base station detect a b/g client, it will switch to b/g mode, which theoritically obey to b/g standard range & speed.

if you wanna extend your range, you can have 2 router, one work as a bridge to extend the coverage. or you can add external antenna if your router support it. lastly you can also try moving the router. for my case, moving it 10cm give me 1 bar better reception.
