No, not at all, That is simply routing information from the Internet  
side of your router to the rest of the world. Your Mac is 'hidden'  
behind that router.

I have hidden in quotes, the function of NAT is not to hide an  
internal network, but to map external network connections to a non- 
routed internal network, but the effect is the same.

Anything on your side of your DSL router isn't reachable from the  
outside; your computer has to go out and make the connection.
