Have you adjusted your party options to allow you to be joined? Hit X in a lobby, then RB to move over to your party options. Ensure that your privacy is set to “Open” or “Friends Only”, and that your max player count isn’t set to “1” or “Locked”.
If you’ve made sure your party options allow you to be joined, it might be your NAT rating. To check, hit the Start button on your controller, move down, then over to “Network Settings” and press A. If your NAT rating is Moderate or Strict, some players may have difficulty joining you. This thread provides some great help on how to open your NAT, but I’ll put the relevant information in a spoiler tag below.
What is a NAT?
NAT stands for Network Address Translation. Basically, your ISP gives you ONE IP address through your Modem. Your Router takes all devices (Xbox, Computer, Printer, etc) attached to the router, and assigns them “private IP addresses”. The NAT then translates these private addresses into the single IP address given to you by your ISP, thus allowing you to connect multiple devices.

Port Forward your Xbox 360
This is where you’re going to make a huge difference at no cost but your own time. Xbox LIVE prefers certain ports on your router for connections. However, sometimes these ports are used by other things on your network. Port Forwarding these ports to your Xbox’s connection “reserves” these ports specifically for Xbox LIVE. This process will also Open your NAT.
To continue with this process, go to a PC you have at home. Open up an internet browser (Internet Explorer, Firefox, Chrome, etc.) and type in your home IP address (this is usually 192.168.1.1 or 10.0.0.1). You will now be asked for a login and password (the login is usually admin and the password is usually password unless you changed it). Now, locate a section called “Port Forwarding” or “Port Triggering” or “IP Forwarding” or something similar (every router is different).
Once you have found the Port Forwarding settings, look for an option called “Add” or “Add custom Service” or something similar. Once you find it, click it. You are now going to enter 10 separate items to this list. When you add an item, it is going to ask you for 4 things. It will ask you for a “Service Name” (or something similar), a “Start Port”, an “End Port”, and a “Server IP Address” (or something similar). For the Service Names, simply put something you’ll remember, such as “Xbox_LIVE1”, “Xbox_LIVE2”, “Xbox_LIVE3” etc for all 10 times. You will put in the Start and End Ports I list below. For the IP Address, put something similar to what your router’s IP address is, but with a different number at the end. For instance, if your router’s IP is 192.168.1.1, then make your Xbox’s new IP 192.168.1.55 or something like that. That last number can be anything between 1 and 255. However, choosing a higher number such as “55” will prevent any problems with other connections in your household trying to use the same number (connections count up, so you’d have to have 55 connections in your house to have a conflict). Next, you will add these connections I list below in the following format (NOTE: your Service IP Address may be different than mine):
Service Name - Start Port - End Port - Service IP Address - Connection Type
Xbox_LIVE1 - 3074 - 3074 - 10.0.0.55 - TCP/UDP
Xbox_LIVE2 - 80 - 80 - 10.0.0.55 - TCP
Xbox_LIVE3 - 88 - 88 - 10.0.0.55 - UDP
Xbox_LIVE4 - 53 - 53 - 10.0.0.55 - TCP/UDP
Xbox_LIVE5 - 77 - 77 - 10.0.0.55 - TCP/UDP
Xbox_LIVE6 - 3330 - 3330 - 10.0.0.55 - TCP/UDP
Xbox_LIVE7 - 1900 - 1900 - 10.0.0.55 - UDP
Xbox_LIVE8 - 2869 - 2869 - 10.0.0.55 - TCP/UDP
Xbox_LIVE9 - 10243 - 10243 - 10.0.0.55 - TCP/UDP
Xbox_LIVE10 - 10280 - 10284 - 10.0.0.55 - TCP/UDP (WATCH OUT, this one’s end is different than the start!)
Xbox_LIVE11 - 1863 - 1863 - 10.0.0.55 - TCP/UDP
Now, you may notice that unlike other IP forwarding guides, I forward 11 services rather than the 5 or so they do. That is because those extra services are for Video connections and such that Xbox LIVE uses as well. Think of it as a FULL 360 port forward, not just gaming.
If you would like a visual representation, I took a screenshot with my iPhone of a port forwarded connection:

(NOTE: this picture does NOT include the “Xbox_LIVE11” service, I will update that later)
Now, you are going to need to open up Command Prompt. You can do this by going to “Start” and clicking “Run” or by holding the “Windows” button your keyboard, and pressing the “R” key. Once it pops up, type in “cmd” (without the quotes) and press Enter. Now you have opened Command Prompt. Now type in “ipconfig /all” (without the quotes) and press Enter. A bunch of info will be listed. Look for a section labled as “Ethernet adapter Local Area Connection”. Look for the info labeled as “Subnet Mask”, “Default Gateway”, and “DNS Servers” and write down the addresses they list.
Now, it’s time to change your Xbox’s IP settings. Go to your Xbox and turn it on. Now go to the System Settings by going to the “My Xbox” section and scrolling right. Open it up and look for “Network Settings”. Select your connection type, and then change your settings from Automatic to Manual. It will now ask you what your Xbox’s manual IP address is. Now input the IP address you chose (I have been using 192.168.1.55 for an example). You will also be asked for your Subnet Mask and DNS Servers, which you can fill in with the information you wrote down earlier.
After you’ve entered all the new information, restart your Xbox, and enjoy your improved connection.
