My router is on, and is hooked up to my verizon modem. My xbox 360 and my computer are both hooked up to the router and all the lights are on but only my computer is working for the internet where my 360...


with verizon, you need to set the modem to full bridged mode so that the connection from your modem will be opened. This certain firewall is called NAT. Your modem and your router has this feature. To disable NAT on your modem, you need to set it to full bridged mode. To disable the NAT on your router, you need to open ports on your router.

You need to open this port on the router for Xbox live to work
TCP: 80, 3074, 53



UDP: 88, 3074

forward it to the ip of your Xbox.

this should set the NAT on your xbox to open, not moderate.

Setting up xbox live


ARRIS modem is a phone/hsi modem. What youll need to do is first turn power off on xbox then unplug the power supply from the back of the Arris modem and unscrew the coaxil/cable wire from the back of the modem for about a minute. Then plug in the power cord to the modem wait another half minute then screw in the coaxil/cable wire....wait for the lights to come back on make sure the online light is solid green not flashing and follow the ethernet cable (Looks like a thick telephone wire) and make sure you have that ethernet cable seated/snapped into the ethernet port on your xbox. Then turn the xbox on and do connection test. FINISHED..IF it's still not working make sure you have Internet service from your provider and if using a router bypass it at first see if you can get onto xbox live without the router. If you can with just connected directly to your arris modem without the router involved. If you do want to use wireless contact your router manufacture and or xbox support at 800-469-9269.

I am having trouble opening the NAT settings so i can play xbox live with this modem/router..I can log on to xbox but I can't play with some of my friends due to the modem/router settings.. When I go to...


The problem in this scenario is entirely not NAT issue . To overcome the issue open some of the port ports viz 80,3074 for tcp/udp on the router and enter the ip address on the router which is the ip you have for the x-box and then try the connection test.

Change NAT to open


First make sure your security type on the router is WEP-Personal. You may need to get the port range for that game or manufacturer. Then enter them in to the gaming tab. This will keep ports open all the time. NAT 2 is acceptable but you want NAT 1. Some internet connections cannot get NAT1.reply if you need further assistance

Connecting my arris modem to x-box live


I have an Arris cable modem and use Xbox live. They work very well together. Most ISP's will only allow one active device at a time. When you switch between you cable modem and your Xbox you need to use a pen and press the reset button on the arris every single time you switch.

How to change my NAT


You need to check first if your router is Xbox Live compatible (all routers will work, but only certain ones will allow an open NAT):
http://www.xbox.com/en-us/support/connecttolive/xbox360/homenetworking/equipment.htm

If your router IS on the list, make sure you have a compatible firmware version (usually the firmware version is written on the router somewhere). If you do not have the proper firmware, you will need to downgrade your firmware (reply to me for instructions on this).

If your router is not on the list, you're outta luck.
