It protects you because it uses NAT (network address translation). It hides your private IP.

ie people see you x.x.x.x ip addres and can do all they want to try access that ip but they will be trying to access a router not a pc. You pc is on a private y.y.y.y address which is invisable. What the router does is note down what service you request and opens the require port only for that service. It can allow access externally but only if specifically programmed to do so.
