Internet Connection Sharing on Windows XP without using ICS

[Hersch]

To all the MSFN Guru's. Please take time to understand my problem and give the right answer in detail. Your help is much appreciated. Now to the actual question:

I have 3 PCs at home in the following configuration and I do not want to use the Windows XP Internet Connection Sharing. I want to route my other home PCs manually so that I can continue to have my own private LAN (workgroup setup) and still be able to acces the internet from any PC. I have my home network on a completely wired setup (Gigabit Ethernet).

PC1 - Windows XP SP2 - 2 Onboard Gigabit NICs - Kerio Personal Firewall - Workgroup Computer

1) NIC1 is connected to my ADSL Modem (Siemens SpeedStream 4200) and the IP is set to 10.0.0.1 with a class A default gateway (255.0.0.0). This is the internet interface and works fine. No issues here

2) NIC2 is connected to my private home network and has the IP 172.10.16.5 with a standard class B default gateway (255.255.0.0). This interface connects to my internal private LAN and I can browse my workgroup computers, printers, shares etc without any problems whatsoever.

PC2 - Windows XP SP2 - 1 Onboard Gigabit NIC - Setup as a Workgroup computer

1) The NIC is connected to my private home network and has the IP 172.10.16.3 with a standard class B default gateway (255.255.0.0). This interface also connects to my internal private LAN and I can browse workgroup computers, printers, shares. No problems here too.

2) It is on this and another PC (with same IP / Subnet class 172.x.x.x, 255.255.0.0) that I want to be able access the Internet using PC1 as the Routing Machine. I believe this is possible but I am a bit lost on how to achieve this. My research has led me to believe that I should use / setup a Persistent Static Route on PC1, so that all my workgroup machines can access the internet. My only issue is that since the Route command is a set of commandline commands (hope this is making sense) and I seem to be hopeless at this stage in typing it correctly, can one of you kind souls spell out the command for me in detail so that I can type it and set the route?

I will be forever grateful to you guys if you can help me with this! Oh and btw, please don't give the lowdown on the route syntax etc. If possible please give me a detailed example using the IPs that I have detailed above.

Thanks in Anticipation!!!!

AnalogX Proxy might meet your needs.

Cluberti thanks for your reply. But the question is about routing and not setting up a proxy or other 3rd party software.

AnalogX installed on PC1 will do everything you require without configuring routing, just making sure that the gateway IP address (and proxy server in any internet software you use) on PC2 points to PC1. This is why I suggested AnalogX Proxy, as it answers your question in the easiest way possible. Don't just assume that because I suggested a product rather than a command means I didn't answer your question.

Cluberti, thanks yet again for your reply! And one more time I wish to get this understood that I want to add a proper route via the command line. I know that i can even setup the native Win XP Internet Connection Sharing and it will take care of my problem. But where is the joy in not being able to figure out manual routing when the OS actually supports it. All the same, I will keep your suggestion foremost in my mind. Because if nothing else works, sure there is AnalogX after all.
