so far as I know the private IP class B range is restricted to 172.16.0.0 &nbsp;- &nbsp;172.31.255.255<br />
<br />
oddly, I checked arin.net and didn't find any entries for 172.70.0.0 or 172.70.70.0. &nbsp;scratching my head... hehehe

I have a 2000 workstation that must use NIC 1 for the internet and have machines on that network still be able to access the machine. From NIC 2 other machines must be able to access the machine but must not use the internet because of ports that must be open on the router I cannot do from NIC2's internet. I also need to make sure that no traffic from nic 1 can go to nic 2.<br />

NIC 1 = 192.168.1.7 255.255.255.0 internet<br />

Windows 2000 is an operating system for use on both client and server computers. It is the successor to Windows NT 4.0, and is the last version of Microsoft Windows to display the "Windows NT" designation. Four editions of Windows 2000 were released (Professional, Server, Advanced Server, and Datacenter Server) that shared a core set of features, including many system utilities such as the Microsoft Management Console. All versions of the operating system support NTFS 3.0, Encrypting File System, as well as basic and dynamic disk storage. The Windows 2000 Server family includes support for Active Directory services, Distributed File System and fault-redundant storage volumes.
