However, we need to keep something else in mind, which Iljitsch's note
hints at. If I'm an ISP trying to sell a low-end service to low-end
customers at a low (but still profitable) price, I need to cut customer
support costs to the absolute minimum. If someone calls up for help
with a configuration problem, that may be six month's of profits from
that customer eaten up in the cost of answering the call.
I find myself wondering, don't they get support calls from customers
having to deal with the problems caused by the NATs?
No, because most customers browse the web, read e-mail, use skype/VOIP
services, and all of those work under NAT. A number of VPN packages
break, (a) that's not that common compared the huge number of
residential customers that aren't doing VPN's for work-at-home setups,
andin any case, those complaints usually gets sent to the company help
desk, and a number of VPN's have solutions that work with NAT's
anyway.
The problems caused by NAT's are the sort of things that don't
normally show up at ISP help desks; the new applications that are not
written, the architectures that are torqued to deal with NAT's, etc.
