It is very important to setup a static ip address, if you are going to use port forwarding. When you have port forwarding setup, your router forwards ports to an ip address that you specify. This will probably work when you initially set it up, but after restarting your computer it may get a different ip address. When this happens the ports will no longer be forwarded to your computer's ip address. So the port forwarding configuration will not work.
What is an ip address?
IP addresses are four sets of numbers separated by periods that allow computers to identify each other. Every computer has at least one ip address, and two computers should never have the same ip address. If they do, neither of them will be able to connect to the internet. There is a lot of information at the following link. You don't need all of it. But if you want to know more about how networks work, you'll find it there. For more information on ip addresses, subnets, and gateways go here
Dynamic vs Static IPs Most routers assign dynamic IP addresses by default. They do this because dynamic ip address networks require no configuration. The end user can simply plug their computer in, and their network will work. When ip addresses are assigned dynamically, the router is the one that assigns them. Every time a computer reboots it asks the router for an ip address. The router then hands it an ip address that has not already been handed out to another computer. This is important to note. When you set your computer to a static ip address, the router does not know that a computer is using that ip address. So the very same ip address may be handed to another computer later, and that will prevent both computers from connecting to the internet. So when you asign a static IP addresses, it's important to assign an IP address that will not be handed out to other computers by the dynamic IP address server. The dynamic IP address server is generally refered to as the dhcp server.
Setting up a static ip for windows ME.
If you have a printer, before you begin print out this page!
Step 1:
Open up the start menu, and click Run. You should now see the following window.
Step 2:
Type command in the Open: box, and click Okay. If command didn't work try cmd. This will bring up a black command prompt window.
Step 3:
The command prompt may look different on your screen, but it doesn't really matter. Type ipconfig /all in that window, and then press the enter key. This will dISPlay a lot of information. If it scrolls off the top you may need to enlarge the window.
Step 4:
I want you to write down some of the information in this window. Take down the IP address, Subnet Mask, Default Gateway, and Name Servers. Make sure to note which is which. We are going to use this information a little bit later.
The name server entries are a bit complicated. Name Server is just another name for DNS(domain name server) server. Some router's act as a proxy between the actual name servers and your computer. You will know when this is the case, because the Default Gateway will list the same ip address as the Name Servers entry. We need to have the correct Name Server IP addresses. If we do not, you will not be able to browse the web. There are a couple ways to get these. The first way is to log into your router's web interface, and look at your router's status page. On that page you should see an entry for DNS Servers, or Name Servers. Write down the ip adresses of your Name Servers. Another way to get the correct Name Servers to use, is to give your ISP a call. They should know the ip addresses of your Name Servers right off. If they ask you why you need them, you can tell them you are trying to setup a static IP address on your computer. If they try to sell you a static external ip address, don't buy it. That's an entirely different thing that what you are trying to setup.
Type exit in this window, then press the enter key to close it.
Step 5:
Right click Network Connections on the desktop, and then click the properties option.
Step 6:
You should see a list of options under the following components are installed. We are looking for the TCP/IP of your internet connection. Click it when you find it, and then click properties.
Step 7:
Before you make any changes, write down the settings that you see on this page. If something goes wrong you can always change the settings back to what they were! You should see a dot in the Obtain an IP address automatically box. If you do not, your connection is already setup for a static ip. Just close all these windows and you are done.
Pick an ip address and enter it into the IP Address box. The ip address you choose should be very similar to the router's ip addres. Only the last number of the ip address should be different. If the router's ip address is 192.168.1.1, I might choose 192.168.1.10. The ip address you choose should end with a number between 1 and 254, and should not be the same as the router's ip address. Every device that connects to your network needs to have it's own ip address.
Put the subnet mask we previously found in the subnet mask section. Thats it for this page. Click the Gateway tab close to the top of this window.
Step 8:
Before you make any changes to this screen, write the settings down! Enter the default gateway we previously obtained into the New Gateway box, and then click Add. You should see the gateway you typed in the installed gateways box. We are down with this window. Click the DNS Configuration tab at the top.
Step 9:
This page should be blank. If it is not blank, don't make any changes to it. If is blank go ahead and click the Enable DNS radio button. Enter a host in the host box. It does not matter what it is, you could use your first name for example. Enter the last part of your email address in the domain box. In the DNS Server Search Order box enter one of the dns numbers we previously found. Click the Add button. The number you entered should appear in the box below the box you entered it in. Go ahead and enter the other dns number. Generally their will be two dns, but if you only found one that is okay.
Click Ok all the way out of these menus. You might be prompted for your windows disc, but usually you will not be. Once you exit these windows you will be prompted to restart your computer. Go ahead and do it. If you have any problems go back and change your configuration back to what it origionally was.
If you find that you can not pull up webpages, the problem is most likely the dns numbers you entered. Give your ISP a call, and they will be able to tell you which dns servers to use. This is a question they answer all of the time. They will be able to tell you what you should use right away.
After you restart you should be done with this computer.
