Using XP as a router ONLY

[Eddie]

Hi,
I am trying to use a Windows XP box as a router only. I have a USB
internet connection (DirecWay), so I have to connect the Internet to a
PC. I then would like to route right through to a Netgear Firewall.
I have added a second network card to create a new subnet for the
connection to the Netgear firewall.

Here is my configuration:

WinXP (Connected directly to Internet)
External IP: 66.82.105.117
Internal IP: 192.168.10.250

Netgear Firewall
External IP: 192.168.10.1
Internal IP: 192.168.0.1 (Internal LAN subnet)

I can ping all of the way out the external address of the XP Box, but
cannot get past there? I can also get to the Internet from the XP
box. I added the following route on the XP Box and it didn't make any
difference.
Route Add 192.168.0.0 Mask 255.255.255.0 192.168.10.1
I have also made the registry entry to allow XP to forward IP packets
and confirmed the line "IP Routing Enabled. .......: Yes" by using
ipconfig.

Thanks in advance,
Eddie

Hi Eddie,

Just so I am clear your network looks somethinglike this?

Client<---------->NetGear Firewall<-------------->XP
Router<-------------->Internet

If this is accurate you need to configure Internet Connection Sharing on
your XP box instead of routing. Your internal network addresses
192.168.x.x. are not routable on the Internet.

Hi Marc,

Thanks for your help, but unfortunately ICS will not work for us.
Functionally, it does work and if I turn it on, I can get to the
Internet from the clients behind the Netgear. However, we use
Netmeeting quite a bit to support our customers with the remote
desktop sharing and Netmeeting remote desktop sharing does not work
with ICS. Which is why I am trying to configure the XP box as a
router and use my Netgear for NAT and protection.

I did some reading from the site recommended by the other guy (thank
you) and it talks about Routing and Remote Access for Win2k. I am
using XP pro and connot figure out how to configure it. I have the
service listed in my services and I can turn it on, but not sure what
to do from there? Also, if you know some way we can get Netmeeting
and ICS to work together, I would be happy to scrap the Netgear and
use ICS.

Thanks for your help!
Eddie
