Sorry for all the dupes under geek@nls.net but it kept saying I wasn't logged in, even though I was so I figured they weren't being accepted...then I saw all of them listed with it saying I was deleted...Why???
Oh well I try again...

I need helpquick.

Assume the following
Firewall internal IP = 192.168.5.50
Firewall external IP = 241.242.255.243

If I needed to yank the firewall because it died and I won't get it fixed
for 24 hours and needed internet access in the mean time...

Could I set up a W2k box with two NICs (one at 192.168.5.50 and one at
240.242.255.243) to handle this routing? What else would be involved?

Just to negate a couple of ideas. THe intitial T1 router belongs to the
phone company...I can NOT TOUCHIT. It of course is on the 241.242.x.x net
lets say it's 240.242.255.242 for grins).

Yes I know how dangerous things would be without the firewall and no I
wasn't quite dumb enough to post actual IPs :-)

Is there another quick workaround I'm missing?

Thanks

Mark

For a quick fix:

2K will not route properly without help!

Set up the two maversion chines as you proposed and install a trial (30 day) of Win Route Pro on it (www.tinysoftware.co.uk). It's dead easy to set up and will do NAT and everything else you may require.

If you wish to spend the time on it it has full firewall functionality as well.

I think it will work. You will of course need to enable routing ("IP Forwarding" in Windoze(r)-speak).

Hi,

I know I'm too late with the answer but... the answer is yes with Win2K. You CAN set up two nics and configure the box as a router between the two cards.

Its reasonably straight forward but will be somewhat slow. Win2K isn't really designed to be a high speed high volume router.

I dont think there's anything else you need to know - apart from that confirmation. You sound like you know what you're doing...

Cheers,
Tim.

You could do this a lot quicker and easier just by going to your local office supply store and picking up a LinkSys DSL router/firewall...

How are u
I have done it in the enterprise.It will work properly.Install windows 2000 server with two network card.Configure routing and remote access with nat support.Be confident there is no problem with it.i worked with it for three month beforeinstalling pix firewall.it will support nat and ip mapping.the only this is u should know how to configure it.

To add on to what the others say it can be done but I would put Microsoft Proxy on the server that away it is natting the address as well as provided built in security that you would need. Because with this you can allow or disallow access to the internet from inside for computers and also disallow certain ports to be accessed as well. This would be the easiest and best way but the simplest would be with the IP forwarding but, this does not offer very much security at all.

by hutchinson

I think this would be easier using Win-XP-Pro or Win-Svr-2K3 and Internet Connection Sharing, with Internet Connection Firewall.

This will at least minimally solve both problems.

Note: ICS will change the local network NIC Address to 192.168.0.1, but once it's running, you can change it to 192.168.5.50 where it needs to be.

Good Luck.

Definitly!!! add the second nic, go to win2k help and get details on how to setup Routing and remote access. Ideally if you had and old NT 4.0 box lying around it would be muche easier to make it a router. Add the second Nic and just enable IP fowarding in Network Neighber hood / tcpIP properties. In win 2k it's a little more work cause of the wizard involved. BE WARNED you will have no protection
