Re: NAT with 2 NICs

Indeed. Use a separate device for NAT. It is a very bad idea to run a DC as a router (unless you use SBS server which is designed to run that way).
Use a dedicated NAT device to make your Internet connection and connect all LAN machines to the switch with one NIC in the private subnet.
Do no use the DSL device for DHCP unless you can configure it to hand out the DC's IP address for DNS. (The DNS relay used by these devices is not compatible with Active Directory). If it cannot do that, disable DHCP on that device and run DHCP on your DC.
All local machines should use the NAT device as default gateway but use the DC for DNS. The local DNS should be configured to forward to a public DNS service (so that it can resolve "foreign" URLs for the AD clients).

Is there some reason that you do not want to use a $59 router? That's the customary method..

I have a small network of 6 PCs running XP SP3 and a server running
Server 2003 SP2. I need to have a file server, user management (so
domain based configuration) with Internet access in all clients.
My ISP gives me a direct ethernet cable based connection with *a fixed
IP address*, only through which I can access the Internet.
This means that I cannot connect the Internet connection to the
switch.
Following are the details:
Internet Connection:
IP: 172.16.98.187
Subnet: 255.255.248.0
Default Gateway: 172.16.96.1
P. DNS:119.160.192.2
S. DNS:119.160.192.3
(I need to log on with a password either using http interface or a
software)
My computer vendor tried with ICS but knew ICS cannot work on a
domabin-based configuration so I tried NAT myself, but I cannot get it
working properly...
First, when I start the server, Windows tries to register itself on the
Internet connection's gateway and so I get "Duplicate name exists on
server" error.
When I click OK in any connection's TCP/IP properties, it shows:
Multiple default gateways are intended to provide redundancy to a
single network (such as an intranet or the Internet). They will not
function properly when the gateways are on two separate, disjoint
networks (such as one on your intranet and one on the Internet). Do you
want to save this configuration?
While trying out differently, once I also found that I could access the
Internet only if I disabled the LAN connection.
I use Quick Heal Total Security and Quick Heal Firewall Pro on server
(I tried disabling it) and Norton Internet Security on clients.
WHAT IS THE BEST WAY TO CONFIGURE THIS NETWORK?
I prefer NAT rather than a router because of small-scale network
requirements. Plus, it _should_ work if _it_is_supposed_to_.
Please help me how to configure NAT correctly...
