 Posted: Sat Sep 18, 2004 3:44 pm Post subject: NAT Router - How secure? |
 |
|
Very quick question, perhaps others have thought about this as well.
My router does NAT and blocks basic ports as 21, 80 and ICMP etc this is however not a true firewall.
How secure is this? Technically how easy/hard would is be for a person to connect to a client behind a NAT based router?
Silly question perhaps? TIA.

You can't connect to a client behind a NAT router at all, if it's properly configured (i.e. it knows which side is the internet and which side it's supposed to be doing NAT for). Even if it wasn't, it'd be pretty hard, since there's no sensible way to refer to machines on the local network from outside.
