Someone please help with this I'm going crazy (Airport/IP/Port forwarding)

Hello

Ok I'm going to explain this situation as thoroughly as I can, because I can't seem to find anywhere how to fix all this up.

I live at a place with 5 computers connected wirelessly to the internet through an Apple Airport Extreme. 2 of the computers are apple laptops, and the other three are PCs, including mine.

What I am trying to do is allow certain ports to be open through the router firewall for my computer. The problem, is that when I click on my wireless network icon down in the bottom right it shows that my IP address frequently changes, and is assigned by DCHP. So when I forward (or map in the airport) certian ports for a certain IP address, it changes on me.

Now someone told me that what I need is to assign my computer a static ip address, but I don't know how to do this. Is this something I need to do through the airport itself?

In the airport administration utility, it says under the network tab that it is distributing IP addresses, and that we are sharing a single ip address (using DCHP and NAT.)

I know this is a long problem but it's driving me crazy and I'd really appreciate anyone's help. Thanks!

When you port forward you have to point it to yourIP address not the gateway address. (router).
Now sometimes if you are all rebooting or turning off the computers, the IP address will usually change, because the router is the DHCP Server and it is handing out the first available IP.
One other way out of it is to never turn off the computer.

 

Hi, thanks for the response.

I know that I have to point the port forward to my IP but it changes between 10.0.1.2-10.0.1.4. Now I've tried forwarding the required ports to ALL these ips. The strange thing is that if I "m on IP .3 or .4, it works, but if i'm on .2, which I usually am, it does not. Still stuck.

I would download the PDF manual for your router and see if there is something else you can do. Everyone would have to agree. I realize you weren't confused about port forwarding. Maybe it is an Airport- PC thing.

 

Looked at that too. Nothing seems to directly deal with what I'm going through with this. For instance, I can't find anywhere "How to assign your computer a static IP ". There's a lot of stuff about when you NEED to do it, and a lot that says "once you have assigned your computer a static IP" but no HOWs

Thanks, I'm mainly hoping someone here has a pc-airport config. and can give me some input, or any other ideas.
