Best W2K nat software

[Dogbert]

Hi,

Just got my new computer

I want to share my ADSL connection through my second lan adapter and M$ internet sharing scheme changes my cards to 192.168.0.1 and 192.168.10.1 while for ADSL I have to be on 10.200.1.1 on the card connected to the ADSL.

So, what's the best (free/shareware/hackable) nat software out there for win2k ?

Save yourself some trouble and get a dedicated router. You can set up DHCP easily, AND have quality firewalling.

If you want to setup NAT in Win2K, try this:

Section I: Host Computer Setup

1) Configure your internet connection for the host: Run the Internet Connection Wizard, check the "I want to setup my Internet connection manually" box. Click the Next button. Check the "I want to connect through a local area network (LAN)" box. Click the Next button. Leave the "Automatic discovery of proxy server (recommended)" box checked. Click the Next button. Follow the rest of the onscreen instructions to setup your mail and news accounts for the host. (Note: My cable provider uses Terayon TeraPro Cable modems which provide dynamic IPs via DHCP, so no special settings were required.)

2) Secure your host computer: From the Control Panel Go into Network and Dial-up Connections, select the NIC connected to the internet: Uncheck File and Printer sharing. Highlight the Internet Protocol(TCP/IP) and select Properties. Click the Advanced radio button. Select the WINS tab. Disable NetBIOS over TCP/IP. Click OK.

3) Share your Internet Connection: Select your Internet NIC again. Select the Sharing tab. Check the Enable Internet Connection Sharing box. Click OK. No special settings are required for the LAN NIC beyond what is done automatically by Windows. FYI: The IP address of the LAN adapter will be 192.168.0.1 with a Subnet Mask of 255.255.255.0. NO OTHER SETTINGS ARE REQUIRED FOR THE LAN ADAPTER.

Section II: Client Computer Setup

1) Configure your internet connection for the host: Run the Internet Connection Wizard, check the "I want to setup my Internet connection manually" box. Click the Next button. Check the "I want to connect through a local area network (LAN)" box. Click the Next button. Leave the "Automatic discovery of proxy server (recommended)" box checked. Click the Next button. Follow the rest of the onscreen instructions to setup your mail and news accounts for the client.

2) The setup procedure for a Windows 98 or Windows 2000 client is identical.

No rebooting or other rigamarol...

MS Internet sharing involves a second card in the main machine. No IP conflict.

Disadvantage to the second NIC method: the server has to be on all the time for others on the LAN to use the 'net. This can run up the electric bill pretty fast if your house has night-owls living in it.

I prefer the Linksys Cable/DSL routers NAT firewall. Very solid and a one time expense of <$100 USD plus it runs on a small transformer/rectifier box that only uses a few watts.

I like that too, but he was asking about NAT and ICS so I figured I'd straighten him out, since he was doing it wrong.

There are very nice routers for sale here but I can't afford it right now.

Ususally my computer is enough to go online except when I'm using it

Besides that, I have no problem keeping my computer online non-stop as a router. It won't cost too much on electricity bill since if it's unused, power consumption can go way down.

It is equipped with two LAN adapters (3com tx905b and Intel pro 10/100)

The 3com goes to the ADSL (Alcatel speedtouch Home) and the Intel is supposed to be used for Lan (via hub or with twisted).

3com configuration for ADSL:
local IP: 10.200.1.1
ADSL IP: 10.0.0.138 (for vpn connection pptp)

How should I configure my other Lan adapter (the Intel one) then ?

You could get a copy of WinRoute, which will do NAT and a few very basic firewall type functions.

My router PC runs Winroute Pro 4.1 and Zonealarm 2.6 as firewall on Windows 98SE, with McAfee Anti-Virus 6 on there just in case. Its only a Pentium 100 with 128mb ram so it wont do much except run Winroute.

An alternative to using ICS under Win2K is to use RRAS, (Routing and Remote Access Services). Of course this will still need two NIC's to work.

[Dogbert]

Like I said, I have two nics.

How do I configure RRAS ?

You need to enable the service first from the Services menu under Administrative tools, once this is running you should see a new option in the Administrative tools menu called Routing and Remote Access. Click on this and run through the appropriate wizard.
