Siemens SpeedStream - Recent Questions, Troubleshooting & Support

http://www.portforward.com/english/routers/port_forwarding/Siemens/Speedstream-5450/World_of_Warcraft.htm should be close enough to get you started (they don't have pictures for the 4200). Check the link for the downloader too - you'll need those ports forwarded if you want to download upgrades. (And you probably can't get both the desktop and the laptop playing at the same time - a port can only be forwarded to one computer at a time.)

First I would open Internet Options in the Control Panel, click on the Connections tab, click LAN Settings and deselect everything that is checked. If you still can't go to a site, try Google Chrome or any other browser to see if they work. It could also be that you have Limited Connectivity. Click Network and Internet Settings and see if check your status there. To reply, please click the Comment button.

Just ipconfig in command prompt and you will get the default gateway and you can actually get the config page to configure the same. Good luck.
