A&A will give you a subnet for as many IPv4 addresses as you need. No extra charge, at least they didn't charge me anything for my /28.

IDnet. Static IP? Check.
Bleh.

34.99 a month for 8mbps with 60gb cap? You're having a giraffe!

To be honest sounds like DynDNS would work just as well in those situations.
No it won't. Every firewall rule I've ever set has been IP based not host name based.

Can we stop telling him doesn't want what he wants and answer the question instead now?

I thought someone else was going to!

Err, by the sounds of it, static IP is something you're going to need. I don't know how it relates to your move though. The additional details seem to imply that the mail server is completely under your control, so I would have thought that you would be able to reconfigure it if you move.

The remote firewall might have to be reconfigured when you move, but that's hardly a serious problem.

It sounds to me like the question you might have asked, is which ISP can guarantee to maintain a fixed IP address across a move of house, and that is a question that I think may be difficult to answer, although I would naturally bow to those who know more.

Maybe the question is simpler, which is the cheapest ISP that offers a static IP.

Whatever the question, I'm pretty sure that those above have different answers.

Every firewall I've seen in a commercial environment will allow the VPN through regardless of the client changing IP address so long as the EU's credentials are correct. Locking to an IP is putting all your eggs in one basket and assuming your provider has some some intelligence and won't reallocate you on a whim... much hilarity will ensue when it's proved they're busy running around a brewery with a wire basket and have done so. Yes, been there, done that. Now locking to an IP inside the network is sensible because the internal gateway boxes don't tend to wander off of their own accord.

To be honest as this is obviously more for business useage than home, I'd be looking at places like Zen who seem to get rave reviews and their tech's seem to be on the ball about stuff, at least that's the impression the PHers who've gone with them have left me with from here. Considering they're a smaller ISP, giving out and more importantly not randomly reallocating a static IP due to fat fingers, should be easy.

How does an ADSL modem/router cope when you have a subnet of addresses? Thinking aloud, I guess you'd have the router use DHCP as usual, but switch off NAT and manually assign the additional IP addresses to the relevant machines inside the network, right?
You mean turn off DHCP and manually allocate addresses in the allocated range? Or turn on DHCP and have it allocate the public IPs? Either way, it wouldn't be the recommended advice. Far better to run a private addressing scheme inside your network.
That much I understand (I actually have three subnets on my internal networks - external, DMZ and internal). Previously I was somewhat confused thinking that the router would pick up all assigned public IPs which of course it won't. Instead, these are available to be assigned to the firewall, other servers, etc.
My Draytek gateway allows me to use Multi NAT- it is currently subnetting only five of the 8 IPs - it is possible with some tinkering to have all 8 usable however.
