We're in the UK and moving from Demon's ISDN dialup to their ADSL package.
The new (non-nat) router has arrived and it has wholly different IP's than
our original Cisco.

The SBS is dual-homed, with the external router on 192.168.1.1 and the
external NIC on 192.168.1.2. The new router does not have an internal NIC so
it looks like I'd need to put the external IP (A.B.C.D) onto the external
NIC - effectively connecting us directly to the Internet. Is this correct?

Also, I would appreciate help on the settings I need to change within SBS to
accomodate this routing change:

1) anything in RRAS?
2) hostname changes from XYZ@ISDN.demon.co.uk to ABC@adsl.demon.co.uk

I don't really want to start fiddling and then find that I can't go back if
there's a problem.

This is probably a simple change and just requires a reboot but.... knowing
SBS... that's maybe not how it is...

Just for clarification, Demon have sent me a non-nat router. It looks like
the router would plug directly to the external NIC thereby putting a public
IP onto the SBS box. Is that bad?

and if you wish to keep your extra layer of security just buy a simple NAT
router (maybe the one you used for ISDN will work) and place it between your
external NIC and the ISP suppled router. This would have the slight
additional advantage of not requiring you to reconfigure your SBS external.
