Carrot, we cannot help you further. We have told you that what you must do, but we cannot tell you how to do it. You need to take some initiative. Look at manuals for your router. Find out if you have other firewalls. Get help from other people in your house. There are plenty of resources here for general information, but everyone's configuration is different, so we can't give you specific instructions for your setup. I've given you a very detailed article. Have you read that? Have you tried the instructions given in it? Have you shown it to your 'network dealer'?
