All you people with NAT'd routers using broadband

Overtone writes "Steve Bellovin of AT&T Labs Research has published a paper showing how to remotely count the number of machines hiding behind a NAT box (in IMW 2002, the Second Internet Measurement Workshop). Your friendly DSL or cable broadband provider could implement this technique to enforce their single-machine license clause. Bellovin explains how to change the NAT software to defeat the measurement scheme, but the fix is complicated and unlikely to appear in commercial home gateways anytime soon."

maybe they'll start charging for people with routers an extra fee :rolleyes:

First they'd have to prove that all the boxes behind the router/switch were accessing the internet.

What I have 5 computers on my home network and only two are setup to use the internet but I want connectivity between the machines?

Which, in reality, I have 4 computers hooked up to the switch, of which 3 have internet access, the 4th one is my daughter's which doesn't allow her to go to the outside world. Firewall stops her.

It wouldnt be that hard with the technique they are talking about unless you have a software based nat setup that reform the IPid to something totally random, or the perhaps exactly the same. Most of your over the counter router are going to let the IPid's of all the computers behind the router send out whatever id they have. They wouldnt be able to see the network activity behind the router/switch so having a computer that doesnt connect to the web wouldnt affect the results.

I do not believe any broadband companies will take advantage of this until its been confirmed for being a valid procedure to enforce their AUP's and contracts without getting sued or pissed off customers improperly disconnected. Perhaps you'll start seeing extra charges on your bill for 'router fees' :rolleyes:

most broadband companies are even selling router/switches to make this happen... I see where AT&T cable may through a fit... becase they can lick my balls anyway... they used to charge per IP and I be they are wanting to go back to that but can't make the money... DSL on the other hand... if the company will not give one fucking static IP how the fuck are they going to charge for nating a network....

I posted up before reading the article. I guess other than peering through packets, they aren't doing anything intrusive.
