Setting up a Static IP Address - Help?

Question

I am trying to setup port forwarding on my internet, and a static-IP address is needed first. I am using the following guides:

http://www.portforward.com/english/routers/port_forwarding/Motorola/SBG900/Utorrent.htm

http://www.portforward.com/networking/static-xp.htm

I did everything the exact way it said, but for some reason I cannot connect to the internet after I manually configure my internet settings/IP address.

Our router/modem is downstairs, and I am trying to set it up on a desktop computer upstairs in my bedroom (using a wireless card).

Am I missing something here? Do I need to configure the IP Address and such from the computer that is hooked up to the modem, or shouldn't it matter?

And yes, I do have the 2 DNS's correct. I got them right off my Motorola Interface webpage.

Answer 1

You actually do NOT need to configure the static IP address on your computer. It can be done on the router and it is so much easier. What model of router are you using? And no you don't have to pay for a static IP, LOL.

Look for a static IP option on the router. If you dont wanna bother with this static IP blahblah, you can also just forget it and just keep updating the LAN IP on the port forward everytime the lease expires. You can find your current LAN IP by clicking start --> run --> cmd --> ipconfig

The default gateway IP address is NOT the same as the LAN address, for example the default gateway might be 192.168.0.1 and your computer's LAN IP could be 192.168.0.101.

You first have to understand the difference between a WAN IP and a LAN IP. The WAN IP is the address used to connect to other computers on the internet while the LAN IP is the one used to connect to other computers in your local network. When you're talking about port forwarding, only LAN matters. What you saw as Dynamic IP on your router's interface is referring to WAN. When you say your IP never changes, you are probably referring to WAN since LAN IPs have a lease expiry date on them that is generated by the DHCP of the router.

i'm pretty sure you have to pay for a static IP address... unless its a workgroup...
