What should my network settings be?

I know in Norton you can do things with network setting and I want to make sure that I have the correct network setup for my case. Here it is. I have 1 desktop computer wich is connected to a wireless router wich is connected to a vonage device wich is connected to a modem. I dont have even one other computer EVER on my network. The wireless router is only used for PS3 and WII. I also called lynksys (people who made my router) and they helped me secure my network. Is there anything I should configure in NIS09 in terms of my network?
