Sounds ghastly. Perhaps you should move to Canada -- 1.5 Mbps for 45 CAD
a month (about 29 EUR) and static IP for 90 CAD (58 EUR) :)

Are there any alternatives? Ireland's a fairly progressive country,
there ought to be some decent competition in the marketplace, or am I
I am fortunate enough to have a very *nix-friendly ISP; they have
numerous customers using Linux and Slowlaris. Some ISPs have carved out
a good niche for themselves doing this. Personally I would be leery of
any outfit that responded to my queries with a question like "What is
Anyway -- to your question:
Generally getting cable DHCP going is a snap, with the following caveat
-- if the cable modem uses PPP over Ethernet, it gets dicey. I don't
know enough about cable modem systems to be able to say if this is even
a possibility. Cable modems use a shared loop, so my guess is that PPPoE
is not possible (or at the very least, not typical), in which case you
would be just fine.
Still, caveat emptor. Check this with NTL first. And if you can show
these clowns the door, so much the better.

They make you buy the modem? Sharks. That's called "offloading
maintenance on the customer". Now, when it fails, they can say "tough
beans, it's YOUR modem". The dirty secret of the broadband business:
broadband terminal hardware fails at a ridiculously high rate. Do you
think they are selling the modems now because it's to *your* advantage?
The firewall is de rigueur if you have any Windows machines. Otherwise I
would say -- keep your system updated, use only ssh to log in
remotely, and keep the number of open ports to the barest *necessary*
minimum, and you can skip the firewall (they are often more headache
than they are worth, IMHO).

Don't let it intimidate you. Lots of people manage the cable modem
without too much grief.
