How do i open my nat for my motorola sbg900

for static IPs: check your router settings. router should be in "bridged" mode so that all the devices have own static "lan" ips like / router will have one lan ip static and one global ip(one it gets from service provider) you must manually give one address of / for your xbox. then give correct subnetmask (default and gateway routers lan ip (default you can aslo put routehrs lan ip as default dns if needed dmz or port forwarding is a tool in your router settings you can assign outside ports to specific ip i have only done manual port forwarding, not sure how dmz works.

Motorola SBG900 NAT problem.

Nat can be turned off in the sbg900, but not recommended, as it also shuts down the dhcp, which is responsible for providing ip addresses to you PC,xbox etc.. I do not believe there is a work around. Nat sometimes limits certain games, but I have not found any games other than COD that I have ever had problems with. bottom line, if you need to disable nat, then you will need to plug directly into modem.

I don't remember the password for my sbg900 motorola router and i need to connect one of my laptops to the network. How do I get the security key. I read another blog that mentioned pressing the reset...

Disconnect the Coax cable from the modem and restart it. Once the "Receive" light begins flashing reboot your computer. If the modem and the computer are communicating, the computer will get a IP address (192.168.0.x with the SBG900) from the cable modem. Shut down your computer. Connect the Coax cable to the cable modem, restart it, and wait for the modem to sync up with the cable company. Once the modem is in sync (Power, Receive, Send, On-line are all illuminated) restart the computer. Once the computer has restarted check the IP address. The computer should have a valid IP address from the cable company. Computers attached to the SBG900 will always get a private (192.168.0.x) address regardless of whether or not the SBG900 is registered on the cable system.

Motorola SBG900 Assign network address to computer

I guess your modem router was already configured well since it worked already previously. It seems that your motorola router is set to broadcast dynamic IPs (DHCP enabled) and your last connected Pc and laptop were configured with static IP. Please check your "network connection" setting and make sure it is set to "Obtain IP automatically"

Setup your IP addresses correctly by checking available IP addies in router.

You will have to know your router addie and your available wireless addies (in router). For this you need to enter router configuration (read manual).

Open network properties, tcp/ip properties, check "use following ip addie and enter something like depending on what your router is setup as available.

Enter same subnet as your router.

Enter DNS server addies from you ISP.
