Providing Net services for the new flat

[ciphergoth]

Geek-only content follows. We currently have cable Internet, with a Linux box providing firewalling and NAT to get the rest of the flat online. Email, web pages, domain hosting etc are done through a colocated box (antipope.org) on which I've configured bind, exim and apache appropriately. It's not this way purely out of geek snobbery - this is actually the only way of providing these things that I actually understand.

However, now we're going our separate ways this probably isn't the most sensible way to do things. When purplerabbits and sibelian move to their new flat, I'd like to set stuff up so they're independent of whatever solutions I have set upon antipope.org.

If I am thinking of it all correctly, they need:

1. A broadband connection (no cable where they're going so this has to be ADSL)
2. Some way of spreading the Internet goodness to all the computers in the flat (eg a NAT box)
3. At least three POP or IMAP accessible email boxes, one for each flatmate
4. Name server records for at least three domains
5. Static web pages for each domain
6. A way of sending outgoing email with a From: field from any domain they own
7. Arbitrary forwarding of many email addresses in those domains, to their own POP/IMAP boxes or to other addresses (eg to me).

So what should they do to get the above services,and how much will it cost? Should they get their ADSL provider to do the lot, and if so which provider should they go to? Should I configure a Linux box to provide NAT as before, or should they get a router and several real IP addresses - in which case, how should they do firewalling? The names are currently registered with gandi.net - can/should they stay that way or will one ISP want to do name registration on top of everything else?

What haven't I thought of?

This is all a bit of a step into the unknown for me, and none of the people in the new flat are serious techies, so straightforward, well understood solutions are very much to be preferred over interesting, innovative, or technically neat ones.

Update: I really appreciate the responses I'm getting here, they're very helpful, please keep them coming!

Just another suggestion for the router - we use the SMC Barricade here at StrangeCo, and we've found it to be a great little dark grey box, doing firewalling and routing perfectly.

Although might you not want to go for wireless networking?

Wireless might be a good idea - you've got things like the Linksys BEFW11S4 that integrate 802.11b wireless access point together with router and cable modem, and contain their own NAT firewall and DHCP server. They've probably got an 802.11g version out if you look around - infact the WRT54G appears to be a g version.
