How do I setup a Window2K DC behind NAT (can it's be happen).
I have cisco 831 with 2 Ethernet interface 0 and 1, Windows2K Server, and couple client pcs.
My Connection is Broadband(cable) with dymanic ip.
even I got dymanic ip, but my WAN IP is hardly change (I have the same IP address for 3 month abd it's haven't change yet). I don't mind to check my WAN ip to get into my network.
My reason doing this is so I can have a full control of my network, and maybe setting up a webserver in the furture.
Thankssss!!!

Inside:
In a small AD environment, I would turn off DHCP on the router.
Set your DC up with a static address on the same subnet as the router.
Use the router as the default gateway and DNS server.
You can either use DHCP on your DC or set your stations up with static addresses.
Use the router as the default gateway and the DC a the DNS server.

outside access:


Obtain a host name from http://www.dyndns.org/services/dyndns/ (free)

Install one of the clients to keep your DNS entry in sync with your dynamic WAN address http://www.dyndns.org/services/dyndns/clients.html

Now you have to determine what services you want to access from the outside, and whether these will be public or private.

Your router can port forward requests for common services from the outside address to your server with a couple of mouse clicks. You have to be aware of the security implications of these decisions.

If your access is to be private, you want to make use of the VPN capabilities of the router.

What services do you want to make available outside of your network and to whom?
