Question : Setting Up Routing and Remote Access (NAT Server)

Local Area Connection 1 = Internet (Adelphia Powerlink/Cable) Running ICS Currently
Local Area Connection 2 = 192.168.0.1 Class C (Home Network with DHCP)

Running Windows 2000 Advanced Server, need to know how to configure RRAS. I've tried using Microsoft's guides.. dont really understand them, i'm not that advanced in RRAS Servers. Anyone can give me a step-by-step instrcution on how to enable it, and run DHCP on the LAN2 connection. I have tried to set it up with Windows defualt settings, but it doesn't seem to work very well. All that happens is that it resolves a DNS address, (www.google.com) then it just sits there trying to access the page. How can I enable the device to share it's Internet Connection, and to open any ports necessary on workstation demand. Any help on this would be greatful.

Answer : Setting Up Routing and Remote Access (NAT Server)

Open up RRAS under Administrative Tools.

Right Click you server and go to Properties.

Under the General Tab, make sure 'Router' is checked and the LAN Routing Only radio button is selected.

Under the Security Tab, make sure that Authentication Provider is set to Windows Authentication, and Accounting Provider is set to Windows Accounting.

Click OK to close and save the changes.

Back in the RRAS window, expand IP Routing and select General.

You should see 3 or 4 interfaces listed on the right side, your adapter connected to the external network, adapter connected to internal network, and loopback interface.  If you don't see them, add them.

On your EXTERNAL adapter, right click and go to properties.  Under the General Tab, make sure 'Enable IP Router Manager' is checked.

Click OK to close and save the changes.

Now do the same thing to the INTERNAL adapter, and also make sure under the Configuration Tab, that 'Use the following IP address' is checked and that it is 192.168.0.1.

Click OK to close and save the changes.

Back in the RRAS window, select IGMP.

Then select the INTERNAL adapter listed in the right and right click on it and go to Properties.

Make sure that 'Enable IGMP' is checked, and IGMP Router is the mode, and Version 2 is selected in the dropdown box.

Click OK to close and save the changes.

Now do the same thing to your EXTERNAL adapter, except make sure the IGMP mode is set to proxy.

Click OK to close and save the changes.

Back in the RRAS window, right click Network Address Translation and go to Properties.

Under the Address Assignment Tab, make sure that 'Automatically Assign IP addresses by DHCP' is NOT checked and that it reads 192.168.0.0 and 255.255.0.0 in the two boxes.

Click OK to close and save the changes.

Back in the RRAS window, Network Address Translation should still be highlighted, right click your EXTERNAL adapter in the right hand window and go to properties.

Under the General Tab, make sure that 'Public interface connected to the Internet' is checked, and 'Translate TCP/UDP headers' is also checked.

Click OK to close and save the changes.

Back in the RRAS window, do the same as the above step, except to your INTERNAL adapter, and make sure that 'Private interface connected to a private network' is checked.

Click OK to close and save the changes.

That should do it.
