(To deflect the inevitable "NAT is not a firewall" complaints, the box is a stateful inspection firewall -- as all NAT boxes actually are).
Hmmm, are you saying that the solution to many so-called Internet security vulnerabilities is for people to use an SI Firewall, aka Simple, Inexpensive Firewall, aka Stateful Inspection Firewall? One wonders why the DSL/cable router manufacturers haven't caught on to this idea before now. If the goal is to actually change people's behavior and get them to secure their own computers then a name change like SI Firewall is actually an important tool. There is a lot of bad press out there for NAT and I wouldn't be surprised if a lot of the amateur technicians of the world are advising their clueless friends not to use it. But if ISPs would promote the use of an SI Firewall (Simple, Inexpensive Firewall) to their customers then perhaps we can get more uptake and an overall improvement in security without fussing around with frenzied patching sessions. --Michael Dillon
