I am setting up an exchange server for the first time and have got a little stuck! I have a domain controller running windows 2000 advanced server SP4. This is the DHCP controller and the only server on the network. The network has approximately 30 computers on it, all running windows 2000. a 1Mbit broadband line is about to be installed, with a router that comes as part of the deal. We shall call the local domain "domain.co.uk". This is also registered via clara.net ISP
I have set up exchange server linked to active directory and all internal mail works perfectly. The problem I am having is sending email to the outside world and receiving from the outside world. Having spoken to clara.net, they seem to think that my exchange server needs a real world IP address. Is the correct? If this is the case, then I see my self needing two routers - one which has NAT for all clients to access the internet and a NON-NAT router so the exchange server can Have a real world IP address.
I am happy to have the mail sent through the ISPs mail server, or sending mail straight from the exchange-server. Whichever seems to be the best option!
The final point - If I need to go with the server having a real-world IP address, then does it need two network cards - one with a local IP address and one with the real-world IP address.
Incidently - IP address of domain controller is 192.168.254.2
IP address of current router (NAT) is 192.168.254.254
DHCP range - 192.168.254.11 ~ 99
If there is any info that I have left out, please let me know.
Many thanks in advance!
