How to Port Forward Xbox 360
This is a detailed walkthrough and explanation of Port Forwarding your Xbox 360.
The actual process takes just a couple minutes if you've done it before, so do not be intimidated by the amount of information and steps I have included. You don't have to have an understanding of networks to do this.
-Simplified 1 (or 2) Step Process-
1) DMZ your router through your modem (if your 360 is connected to a router and not a modem).I have attempted to identify and address all the scenarios possible with this process, and to include every piece of information that is needed and helpful to get the job done.
-What is Port Forwarding?-
All communication (data traffic) that occurs between your 360, Xbox Live servers, and other Live users travels through specific ports. These ports are managed and monitored by your modem and/or router. Both the modem and router generally use NAT and a built in Firewall. When using a computer, these 2 things are usually a good thing, for they prevent a large amount of illegimitmate traffic from accessing your computer. On a 360, however, they just interfere with legitmate network traffic. Port forwarding is the term used for "opening" these ports, allowing unrestricted traffic through specific ports only to a specific destination, which in this case is your 360.-What is DMZ Hosting?-
DMZ Hosting is a feature included in most routers and modems. It allows you to give unrestricted data flow to a specified IP Address, thus opening all ports to that network device. DMZ Hosting a computer is NOT recommended even with personal firewalls and Anti-Virus programs installed because it creates a severe security risk, so please don't do it.-What is DHCP?-
DHCP stands for Dynamic Host Configuration Protocol. DHCP assigns ALL network devices on your LAN an IP Address. This address is DIFFERENT than the IP Address of your actual LAN (the # your ISP assigned to you; I.E. what identifies your location when online). The reason EVERY network device needs it's OWN unique IP Address is so data can be routed to the right device. You wouln't want the H3F home page data being sent to your 360 would you? Your modem/router makes sure this doesn't happen by assigning unique IP Addresses to every device, so data traffic can flow to the correct places.-What is the difference between a Modem and Router?-
Everyone with a high-speed internet connection has a Modem. Usually your ISP supplies it to you for a fee. This is the box that is wired directly to the wall, and usually is installed next to your home's main PC. But, most Modems have very limited ethernet ports, and thus people often buy Routers to expand their network. Routers have basically the same job as modems. Both generally have a NAT and Firewall, and will often deny data traffic they believe is not legitimate. This is what causes you to not hear some people over XBL, or not be able to connect to some people at all. If your 360 is connected to a ROUTER, you have TWO sets of NAT you must break down.-Terms to Understand-
Internal IP Address - Modems and Routers have an Internal IP Address. This address is static, and was originally set by the manufacturer. The Internal IP Address is the number we use to access that device's Firmware Interface Via a Web Browser. The Internal IP Address is the template for any IP Addresses it must assign using DHCP to devices connected to it.-Reasons for port forwarding-
1: Determining your Configuration
Determine your network configuration. The 2 most common configurations are as follows:2. Displaying LAN Information
If you are using a router, you are most likely behind 2 sets of NAT and Firewalls. Port forwarding your router only addresses 1 set. You must forward any traffic that is destined for your router through your modem. On a computer that is connected to the router, go to Start -> Run -> Type "cmd" and press enter -> Type "IPconfig/All" and press enter. This displays all your LAN information. It should look something like this:3. Accessing Router Via Web Browser & External IP Address
The Default Gateway should be the Internal IP Address your router was programmed with by the manufacturer. This is how you enter your router's firmware interface. Enter this number into a Web Browser. Often it will be 192.168.1.1. You may then be prompted for a username and password, which unless the defaults have been changed, were set by the manufacturer of the router. They are usually "admin" and "admin" or "user" and "user", or "admin" or "user" with NO password at all. Consult this router list or google your router to locate its default username, password and interal IP Address. Once inside your router, locate its external IP Address that your modem assigned it with DHCP.4. Accessing Modem Via Web Browser and DMZing Router IP Address
Now you must DMZ Host your router through your modem. Your modem's Internal IP Address must now be entered into a web browser, the same way you accessed your router. Under the IPconfig/All information, your modem may be your first DNS server. If not, you can use the router list or do a google search to find out what it is. Cable modems are often 192.168.0.1 or 192.168.100.1. Once inside your modem, locate the DMZ Hosting option, and enter the external IP Address of your router that we located in step 3. Save this setting; your modem may now restart. Now all data destined for your router will be unaffected by your modem's NAT and Firewall. The following is the DMZ option in my Actiontec Modem:5. Locating IP Address of 360
We must now either DMZ Host your 360's IP Address or port forward all necessary ports manually through your modem/router (depending on whether you have a modem or not, this step and those that follow assume you do not have a router, or that you have DMZ Hosted your router through your modem already). We first must know the IP Address assigned to your Xbox 360. On the 360 Dashboard, go to System Settings -> Network Settings -> Configure Network. Write down the current IP Address. Note: With DHCP, the IP Address of your 360 may change if you do not use your 360 often. To prevent this, copy all the current entries for IP Settings and DNS Servers into the Manual Configuration option on your 360. The following is the Network Configuration page of the 360 where the IP Address is displayed:6. Accessing Modem/Router Via Web Browser
Enter the Internal IP Address of your modem/router (the one the 360 is connected to! Not both, or the other!) into a Web Browser to access its firmware interface. To locate this, go to any computer that is connected to the modem/router and go to Start -> Run -> Type "cmd" and press enter -> Type "IPconfig/All" and press enter. This displays all your LAN information. The Default Gateway should be the IP Address we need. If not, you can use the router list or do a google search to find out what it is. Cable modems are often 192.168.0.1 or 192.168.100.1, while routers are usually 192.168.1.1.7. DMZing/Port Forwarding 360 IP Address through Modem/Router
Once inside the modem/router, simply locate the DMZ Hosting option and enter the IP Address of your Xbox 360. If there is no DMZ option, you must manually port forward each necessary port (listed near the top of this post). Locate the port forwarding options in your modem/router. All firmware interfaces are different, so I can not tell you where it will be located. But, if you refer to this database, you will see step-by-step instructions on locating the portforwarding section of your modem/router. Once there, make entries for each port with the IP Address of the 360 as the destination. Save these settings. The following is a DMZ entry within the Linksys WRT54G Router:8. Confirming Successful Port Forward of 360
Under Network Settings in the 360 Dashboard, test your network and confirm your NAT is Open. Note: An Open confirmation by the 360 test does not always mean your ports are forwarded properly. But if it doesn't say open, they definitely are not. Hopefully your results look like this:-Thing that complicate this process-

Thanks a lot, very detailed and cleared up many things =)
1) DMZ your 360's IP Address through your modem/router.
2) DMZ the IP Address of your router through your modem, if you use a router.
But, if that's all I put, would you know what DMZ is, or where to find it?
Would you know how to find your 360's IP?
Would you know how to find your router's IP?
Would you know how to find your modem/router firmware interface?
These are the things that people have to learn, and when people put just the actual things you have to do, it would only help those who are already very knowledgeable in networking.
DMZ is the fastest, easiest way to ensure that your 360 is completely open.
Never have a heard of anyone exploiting a DMZ-ed 360, but maybe someday it will happen? I doubt it though.
