yeah..... my question is why would you *need* ICS after getting a wireless router since a wireless router:
1) does DHCP and NAT (and "real" IP routing)
2) usually has multiple ports for LAN connections
3) can protect the network behind it if it is properly secured.

ICS is band-aid service for people who don't/can't invest in a hub/router.
It isn't very robust (its easy to overwhelm with things like... torrents). It has no/terrible knobs for routing functions like portforwarding, etc.

If you're setting up a two-tier network (DMZ fronting an internal network).... you probably ought to go with two routers anyway for port application control.

If you really want to do this.... the network between your ICS computer and the router will have to be set to a IP subnet other than 192.168.0.X (ICS forces a win for use of 192.168.0.1 on the internal LAN card). The router should be able to handle working in another private range (like 10.0.0.X) so you'd set your PC's external net port to 10.0.0.2 and your router's internal net port to 10.0.0.1 for example.
