We must fight spam for the same reason we fight crime: not because we
are naive enough to believe that we will ever stamp it out,
but because we do not want the kind of world that results when no one stands against crime. - Geoffrey Welsh

But I want to see the same clause in their advertising, at least as prominent as the claim of "unlimited". If it's limited, they shouldn't be able to deceive people by claiming otherwise.|

The problem is that the consumer routers may have bugs that allow attacking from outside (e.g., via strangely-formed packets that overflow a buffer), and their software is usually not patched once the model is no longer current. I use MikroTik routers now. They're not expensive, and they are incredibly powerful for small machines. And they keep updating the software, which runs across a wide range of current and older models. However, they're also not designed for consumer installation; they're not well documented, and all that power assumes serious expertise. Even with the decent GUIs they now have. They're mostly installed by ISPs; someone there usually becomes expert at MikroTik's software, RouterOS, and comes up with a configuration. We use also RouterOS as a serious firewall, the kind with lots of custom rules, not the simple home kind.|

That may not be enough, experienced ample enough times, with "hidden" back doors (until the hacker discovers them) with no user control over who can access what, and/or hard coded admin username/passwords with no user control or view that they exist. This is addition to test-ports that are baked into ADSL routers, like the telco spec TR-067 where the ISP can remotely trigger firmware updates, testing, etc. -- Doug McIntyre email@example.com|
