How to Install Exchange Server on a LAN behind a firewall, and still have SMTP mail access
I am preparing a test installation of exchange.
1) I have only 2 public IP addresses.
2) I have a registered domain name and it is pointing to one of the public IP's
3) I have a linksys router with NAT/firewall built in.
4) I am setting up a new DC - win2k Server using the public IP address and a second NIC
to access the private LAN behind the firewall/NAT.
5) The linksys router has the second IP address
I need the following information.
Let's assume that I mange to set up the DC correctly with AD and DNS. I'll check the microsoft howto.
I also read the exchange howto - install about usig DCpromo to upgrade AD to have the exchange extensions.
What I want information on is
a) WHat do I need to do to setup access to the internet through either the multihomed DC or the linksys router.
b) Could I use just the linksys router without a multihomed DC , and still host exchange and a domain ( abc.com ) ?
c) I want all mail sent to the Domain name to go to the exchange server.
d) I want to be able to send mail thru exchange and SMTP.
Points will be given for partial / complete answers with full details.
I will divide this question up to distribute more points as needed
Thanks in advance !!

a1) If you only require internet access to the DC/EXCH box, then you will need no other software - as long as the router is configured to route data properly.
a2) If you require the router to share internet access to the private lan, then you will require either the router or the DC/EXCH box to route traffic, and use NAT. I'm not familiar with the router, but it should do it, otherwise, use RRAS on the DC/EXCH box.
Note: for both a1 and a2, you do not have any firewall in place, unless the router does. You should examine the router anyway, to make sure that traffic can penetrate the router, and get to the DC/EXCH box.
b) Yes, you will have to edit the DNS records, and point the SOA at the DC/EXCH box (and make sure it is setup to deal with mail addressed to abc.com).
c) If you are using the DC/EXCH box as the sole SMTP transport, this will be done.
d) see c.

Thanks for the answers so far.
More details.
Since I only have 2 IP addresses, one for the DC and one for the linksys :
I am worried about the exchange server being on the private LAN.
SInce it is NATed, how will mail reach it ?
Please give me some details.
Thanks !
