NAT Router / Security?

Question

Suppose I have a NAT router that has a public IP address, and a computer behind the NAT router, with a local (private) IP address, such as 192.168.x.x.

Assuming:
1)  That I am not doing any port-forwarding on the NAT Router
2)  That the computer behind the NAT router never makes any connections to any outside IP addresses

Then - Is there any possible way that this computer could be attacked from the outside?

check here:

scroll down to the middle of page one and click 'proceed'

on page 2 in the services box, click the top left item entitled file sharing.... GRC will then examine your system and report back, then do the same with common ports; all service ports; messenger spam and finally browser headers.  The complete scan shouldn't taken any more than about 3 minutes, tops.

if they find any open ports, just google "how to close port [[pick a number]] "

good luck
