Hi Bob,
I see from the link I posted that this device seems to be multihub sort of device allowing Phones and TV services as well.
If it does do this it may be easier just to add a router beyond the FastLive box.
Then you could Port Forward to the new router with Staic Addressing and let this new router do DHCP and UPnP to allow both computers.
This may be cheaper than a new modem anyway.
I have a Linksys router that does this.
Defcom uses a Netgear DG834 variant (T I think) modem that he uses with an ADSL2 connection at about 22meg download speeds.
Alcatels are popular on the continent but avoid those with Version 5 or 6 firmware. This can not Unbind SIP from port 5060 that it has and earlier firmware (4.2.9 and below) can have done.
Avoid MIMO devices that supposedly extend the range of the wireless cover, or Pre-N devices that try to guess the next incarnation of the 802.11 wireless format. Both these devices have problem with iChat (though some people are now reporting success)
If this device you have does do multiple service then I would just add a router to the network.
