Just to clarify your position before any further advice is offered, do you want the router itself to obtain one of the static IP's? The reason I'm asking is typically with multiple static IP's the router will obtain a dynamic IP by default, the router needs to be configured to make use of the static IP's but doesn't get one itself, it's purely acting as a gateway for those addresses and the IP's themselves would normally be assigned directly to devices on the network.
You'll find this will happen with both the home hub and the business hub and there's no way around it with those routers, the home hub doesn't have the option to configure multiple static IP's anyway and the business hub will always get a dynamic address. Some 3rd party routers will allow you to specify one of the IP's on the WAN port and use it as a static IP, as long as the gateway and subnet mask are obtained automatically then this will work, but obviously this isn't a gauranteed method and we can't officially endorse that type of setup in case changes are made to back end that stop this from working (which I don't foresee, but never say never).
I have had this working on a Netgear DG834G and various BT Voyager versions, the netgears drawback is the fact you can only run NAT or no-NAT, you can't do both... last check the Voyager will allow multiple subnets to be configured so you can make use of a private NAT network and your multiple static IP's in no-NAT mode. Being 3rd party routers we couldn't offer support for those if you called the helpdesk, we would help with the Voyager 220v but that may not suit you as it only has 1 ethernet port and no wireless, all other voyagers are considered 3rd party but the firmware is more or less identical across the board bar wireless section.
Hope this helps
