Internet Connection Sharing using netsh

hello,

I use two windows XP machines. Machine1 has two interfaces. One connected to internet. The other is static ip "172.16.1.1 ". This interface is connected to Machine2 that has static ip "172.16.1.12" with gateway "172.16.1.1 ".

Now I want to access internet in machine2 via machine1.

I did the following steps:

1. Enabled "IPEnableRouter" register setting to "1 "
2. Enabled NAT by commands
netsh routing ip nat install
netsh routing ip nat add interface "Internet" full
netsh routing ip nat add interface "Local Area Connection" private
netsh routing ip dnsproxy install

Even then, I am not able to access internet. Is there anything more that needs to be done, to access internet.

Thanks in advance

Thanks tony,

I disabled firewall. I prefer to do it by netsh. I have systems in this way:

Machine1(172.16.1.12)-----(172.16.1.1)Machine2(10.132.14.1)------(10.132.14.23)Machine3

from machine1, I am trying to access Machine3 via Machine2. I am configuring Machine2 to make this happen and got stuck at netsh. Please suggest me ideas.

A 39.00 router? I'm just saying.

Good One Scott.

From Machine1, I issued "ping 10.132.14.23 "

In Machine2, sniffed packets on "10.132.14.1" interface. I could see the ICMP echo request(Src: 172.16.1.12 & Dst: 10.132.14.223) and Machine3 is trying to reply to 172.16.1.12, which has no route in its routing table.

This means that IP address 172.16.1.12 has not changed to 10.132.14.1 at Machine2(NAT hasnt enabled). I was asking is there any way we can enable NAT, so that IP address translation is done.

If I do that, the packets intended for both the ip addresses travel through both the interfaces.

Please mention how NAT can be configured to make translation of ip address from 172.16.1.12 to 10.132.14.1.

I am badly in need of it.
