Sharing internet connection by using several LAN cards on one host computer

I'm aware that there are many threads and questions already posted about internet connection sharing but I find my problem very specific. I have one computer running on Windows 7 and it has 3 LAN cards:
1) internet connection
2) connection with 2nd computer
3) connection with 3rd computer (via WiFi, ad-hoc)

The idea is simple - I want to share the internet connection with 2nd and 3rd computer. I belive I understand idea of ICS but there is one thing bothering me - when enabling ICS I have to specify the interface that I want to share internet connection with. When I set it to connection [2] there is no problem with internet connection on the 2nd computer but still there is no internet on the 3rd one and vice-versa. The whole configuration was running fine on XP, but as far as I remember there was no need to specify the 'share' interface so the [1] connection was shared with all others. Is it possible to set up such configuration on Windows 7 without using any additional switch or router devices?

Thanks in advance!
