Multiple NICs and routing and remote access question.

Hi,

I've got a PC with Windows server 2003(64-bit) and multiple NICs. The
purpose of multiple NICs is, one NIC is connected to the Internet and the
other NIC acts as a DHCP server to a private network.

The requirement is,
I have to make sure that the traffic from one NIC does not mix with that
of others
and traffic from the private network cannot be accessed from other NICs.
I have to use IPSec for private network.

Now, I've got couple of questions.
1. Can I meet the above requirement using Windows Server 2003's routing and
remote access tool? Is so, could you please let me know where can I get
resources for configuring routing and remote access tool.

2. Do I need to make my server PC as a Domain controller to implement IPSec
policies for multiple clients in the private network.

Kindly let me know.

Cheers,

Naveen.

1. you can use NAT.
2. it is not recommended to setup DC on a multihomed server, especially this case.

It won't "mix" in the first place and you don't need IPSec.

Traffic never "mixes" to begin with,...it may "route", but that can not
happen unless you use RRAS to enable routing. If the machine is supposed to
"share" the Internet connection then you would use RRAS to create a "NAT
Server" out of the machine. IPSec still has nothing to do with it.
