surely they just tell one ip to forward all packets to the IP you get from
your ISP (thus your router's external interface) and it'd work from there.
And yep, I know there are.. just looking to see if there's a "better way" .

The problem is having either 1Mb business adsl, and get the no-nat option
which gives you a block of 8 ips (5 usable), or the 2Mb home adsl which is
cheaper, but doesnt have the no-nat option.
Faster downloads are important, but at the same time 1 ip is one too short,
as a server of mine needs to have a public ip for various reasons.

Hi Ian,
If you are on one of our home accounts we will be happy to assign you
a block of 4 IP addresses (giving you two usable IP addresses)
immediately. To do this simply raise a Contact Us ticket requesting
the change.
If you wanted more than that you would have to be one of our business
accounts, where we will provide 8 IP addresses with justification.
Regards
Josh

/me starts to rethink his adsl plans again 
Basically when the time comes (to upgrade to adsl) Ive just the two boxes
that need unique ip's. One being a nat gateway, the other a private linux
box that needs public access (thus own ip for proper host/stats reporting).
So what your saying is a home account with 4 ip's this configuration is
fine? And yes, i know the router can do NAT, but it doesnt do filtering (not
yet anyway ;p).
Kind Regards,
Ian

Somehow the information that packets for your IP were to be sent to to
your ISP would have to be propagated around the world to any machine
that wanted to contact you. This used to be possible when the
internet was smaller, but if hundreds of millions of IPs had to be
individually routed it just wouldn't work. Allocating them in blocks
greatly simplifies the problem.
Incidentally, it's not just storing the routing tables that's a
problem - the memory to store every possible IPv4 address would only
cost a few hundred pounds - but passing the information around and
updating the tables.

Agreed that it cant really be done, but you could get PI space direct from
RIPE and if you ISP would announce the route into BGP it would be
possible.
This is assuming any ISP would
a) announce a route into BGP for a DSL customer (very doubtfull)
b) That your LIR/RIPE would assign PI space (highly unlikely)
c) Also nearly all providers filter BGP route at /24 so you'd need at
least a class C to get full global routing without your routes being
discarded.
Most ISPs should allow you to have a 8 IP block, I know we would if you
had the right justification for it.

We have a couple of customers on ADSL with PI space they had already. It
is rare though.
The other possibility - which have a few people on but not an "official"
service is tunneled IPs. We have done it where one in a set of offices
has to have a Kingston line or a Manx line and they could not have
service from us but all of the otehr sites are fixed IP, that sort of
thing. Works quite well. We have got one line in Colombia - well, some
IPs in Colombia anyway, that work over tunnels and quite happily do VoIP
as well.

Like I said in reply to Josh, long as i can setup one or two private boxes
with public IP's, thats all I need. TBH 5 is more than I'd ever need.
Current setup as Ive mentioned is adsl router, nat box for controlled net
sharing and a linux server that needs to be able to report client addresses
correctly.
Kind Regards,
Ian

With a block of 4 IPs one would be assigned to your router when you login by
our RADIUS so this would only give you one spare I'm afraid.

It is possible if only one machine to have a global IP of its own and one
for the NAT box then 4 is all you need if the router can work in as an
ethernet modem (ie not requiring an IP address of its own but instead just
acting as the ethernet to ATM bridge).
You allocate the first of the 2 usable IP addresses to NAT box, the other to
the server
eg
-----NAT BOX-----
eth-0 (plugged to router) 81.0.0.5
eth-1 (NAT subnet) 192.168.0.1
eth-2 (non NAT subnet) 10.0.0.1
-----SERVER BOX-----
eth-0 10.0.0.2
veth-0 81.0.0.6
Then manually set up the routing on NAT BOX
destination 81.0.0.6
subnet 255.255.255.255
next hop 10.0.0.2
interface eth-2
I run a setup like this successfully... the server is not NAT'd
