Question about routers

If I use a router to share a connection between 3 computers, am I correct in believing that network shares on the computers are not accessable to the outside world?

Question being: if I share the full C:\ drive on one computer behind the router, will I have security issues?

Thanks,

If the PC behind the router has a public IP address, and the router is doing unfiltered routing, yes, you could have issues (add a password, though, and you remove most of them).

If you're using a NAT router with private addressing, then nobody can connect directly to your machine because it doesn't "exist" on the internet.

Each PC has it's own private address - the router will be the only one with a public address....

Thanks heaps!
