Siemens: Firmware

Hey there Sludg!

Can you confirm that your Siemens Model 4200 is just a cable modem and not with built in router. Just to rule out that your not having double NAT layers.

You should also secure your wireless network.

Make sure that your router's firmware is up to date.

Just a note: When opening ports with Port Forwarding make sure you have disabled UPnP and DMZ.

Some NAT problems are subtle and don't appear in the Test Xbox Live Connection test. Most likely there's a port blocked... ports can be blocked in your router, modem, or at your ISP. Since the Xbox 360 uses different ports than PCs & Macs use, you can't
see the effect of a port blockage except on the Xbox. A sequential power cycle is the first step in clearing a port blockage:

1) turn off the Xbox then

2) unplug the power from the Siemens.

3) Wait at least 30 secs then replug the Siemens power.

5) Wait 'til the light on the front of the Siemens which says DSL is on solid (not flashing), then turn on the Xbox.

If that does not resolve it, then the next step is to make sure UPnP is enabled. I see your Siemens uses 192.168.1.1 as the IP address, so go to a web browser (IE, Firefox and Safari preferred), enther the IP address in the address bar, and go to the control
panel of the Siemens, then find the UPnP setting and make sure that's enabled.

If that does not resolve it, then set up Port Triggering to make sure port 3074 opens up for UDP and TCP and port 88 opens up for UDP when the Xbox needs it.

Make: Siemens Speedstream

Model: 2624

I've changed the wireless channel and I have enabled UPnP, but that was only yesterday when looking through what could be wrong. I have Comcast as my ISP.

Greetings Zero!

Is your console directly connected to the siemens se567?

Could you access your router's utility interface and turn off/disable the firewall. Save/Apply and reboot your gateway.

Post back and let us know how that goes.

Thank you for providing your router. Doing some research, I came across this webpage which should help you portforward your router. http://portforward.com/english/routers/port_forwarding/Siemens/Gigaset-SE567/Xbox_Live_360.htm
