ICS provides Dynamic Host Configuration Protocol (DHCP) and network address translation (NAT) services for the LAN computers.
All packets leaving or entering the LAN are sent from or to the IP address of the external adapter on the ICS host computer.
Typically, ICS can be used when there are several network interface cards installed on the host computer.
The service is not customizable in terms of which addresses are used for the internal subnet, and contains no provisions for bandwidth limiting or other features.
It provides NAT services to the entire 192.168.0.x subnet, even if the address on the client was set manually, not by the DHCP server.
