First off, I would like to say I've been working on this for several days and am becoming very frustrated with this problem I've been having. Any information and help that clears some things up would be greatly appreciated. That being said, my issue is very similar to this post: http://www.geekzone.co.nz/forums.asp?ForumId=8&TopicId=1245

I have 2 computers in my room, A and B, both with XP Home. Computer A connects to a wireless router downstairs (DI-624), and I want to set up ICS with computer B via crossover cable. From days of research and process of elimination I've gathered that, and I could still be wrong, that computer A's IP needs to be 192.168.0.1 for ICS to work. Is this true? I've re-issued every IP in the house to avoid 192.168.0.1, and changed computer A's IP to static to obtain it specifically. Still a no-go. I've noticed that computer A's IP is 192.168.0.101, instead of the specified 192.168.0.1, any idea why this is happening? Is there something I'm missing? Please offer any advice or instructions you may have. Thank you.

I've also come across this link: http://support.microsoft.com/kb/308006/en-us

In it it says that an "internal adapter" needs to be configured to 192.168.0.1. What exactly does this mean? Is this seperate from the computer's IP? If so, how would I go about changing it?

Ok, let's examine things... To use ICS you need two network interfaces on the host PC. One connected to the LAN (NIC A) and another being used to share the LAN (NIC B). The client computer only need one network interface (NIC C).

To correctly configure ICS the NIC B must be 192.168.01. The default gateway can be your router's IP address, and the DNS server addresses are best if filled with your ISP's DNS addresses.

Then you will wil create the ICS by right-clicking NIC A and sharing it to NIC B. NIC A can be any valid address on your network, no need to be static at all.

The main problem is that you can not have more than one device using the same IP address. So if your router is 192.168.0.1 (likely, but of course it's your network) then you will need to change it to something else. Also it may be that your router is providing IP addresses automatically (DHCP), so in this case, make sure to configure it to use a range that excludes 192.168.0.1, for example starting from 192.168.0.10, leaving 192.168.0.5 for the router itself.

If this is a cable modem connection be sure not to change the router's WAN IP address, and if it's a DSL network make sure the modem itself is correctly configured.
