I have set up Internet Connection Sharing in my Windows 7 laptop. Currently the IP range alloted for ICS clients from DHCP is in the range of 192.168.137.x. I am not able to find a way to change the range manually to 192.168.0.x range (i.e the same range as my wireless router)
I tried googling but did not find any answer.
EDIT: I found this http://support.microsoft.com/kb/230148 from microsoft site , but this article may be very old, since I am not able to find that particular path in my regedit.
EDIT2: This is the specific scenario for which I need to do this. Note: I am not going to buy new hardware for atleast some time. (I know that buying a multiport wifi router will solve my problem) I have a pocket wifi router, which has only WAN port and no ethernet out. I have a desktop which has only ethernet and no wifi. Desktop has a i7 processor and 16GB RAM. So very powerful. I have a laptop with windows 7 with both wifi and ethernet. But my laptop has very low config and not very powerful I have set up ICS in my laptop to share internet connection in my laptop.
I have RHL Linux running inside a Virtual Machine in my dekstop. I want to set up a site-to-site VPN from my Linux VM inside desktop to my friend's VM in his house. His comp is also behind a NAT. I wanted my wifi router to be able to ping my desktop (so that i can set up natting in my pocket wifi router) and I thought that by giving the ip address in the 192.168.0.x range, I can achieve this. But I was wrong. My desktop did get ip address of 188.8.131.52 after trying out the below solution by @michael-kjorling . But neither my desktop nor my wifi router can ping each other.
So is there any way I can achieve this?
