To properly configure the host with static settings, you must provide the host with IP address and host name resolution information. Also, you must configure the ICS host (the Windows XP-based computer that is running ICS) with the name of the client so that name resolution can function properly.

|How to Configure Windows XP ICS for an Internal PPTP Server|
Windows XP includes support for Internet Connection Sharing (ICS), which provides the ability to share an internet connection with other computers on a local network. ICS in Windows XP allows services to be mapped to hosts on the internal network, so that requests coming from the internet and destined for a particular service will be redirected by Windows XP to the appropriate computer on the internal network.
For example, you may want to place a Point-to-Point Tunnelling Protocol (PPTP) server on the internal network and configure Windows XP ICS to forward the Virtual Private Networking (VPN) traffic to the PPTP server. This article describes the process that is required to map PPTP back to an internal host, so that an incoming VPN connection can pass through the Windows XP ICS computer. For the purposes of this article, it is assumed that the PPTP server is already configured properly and is able to accept PPTP connections from clients on the local network.
