Comment They know your IP address? (Score 1) 319
Most gaming services don't show other users your IP address as things like a DoS could happen. Unless they are the admins of the game or you are using a third party service that they have access to such as a Teamspeak/Ventrillo server, guild/forum web server, etc. Be careful of what you visit.
Also, even the best router is not going to stop your internet pipe from getting flooded with incoming packets.
