Hi.

Why is it that many ISPs, including those that supply DSL, forbid home
servers? Especially curious about the DSL -- with all that bandwidth,
why the nonos? Does it have something to do with the way the networks
work (ie. a server would somehow rob bandwidth from other users?)? Does
it have to do with greed -- to force you to pay w00h00 $$$$$$$$$$$$$$
for it? Does it have to do with security? If so, would a
tough-like-a-mountain-secure server be okay or would you still be in
hot water? And if it was still forbidden, why? Would it be because of
other reasons still being applicable (like the bandwidth thing, or the
greed)?

I know the reasons would probably differ from ISP to ISP, but I'm
courious about what it is, in general.

Probably due to so many clueless Windows users failing to do security
updates and unknowingly running an easily infected web server or opening
infected e-mail, that in turn spreads those infections. There are still
infected machines trying to spread the old Code Red and nimda worms.

My ISP only blocks a few ports (related to MS Blaster worm, etc.), and not
port 80. If I open my port 80 in my firewall, apache gets almost
constantly hit by those infected Win boxes. So I resorted to a default
virtual host that logs separately, and gets log rotated to the bit bucket.
The only virtual hosts with any content are my no-ip.com names (dynamic
DNS) that I mostly use privately. The worms can't find those.

So even if I had a super-secured server, would they still try and shut
it down?

Might well, if they don't want to support the bandwidth
it takes. A lot of the ISP is run by marketing, who think
in terms of products and strongly avoid commoditization.

If it somehow came to their attention, they might feel they had to in
because you're kind of thumbing your nose at them. My bet would be that,
basically, they don't really care. However, you really shouldn't do business
with a company that's not providing you the service option that you actually
want. You'll be a lot happier when you're not doing something you agreed not
to do.
