On the host which is used as the Internet gateway (see chapter 2.1 Selection of IP addresses for LAN), start WinRoute's installation. Select Full installation.
If the installation program detects the Internet Connection Sharing service, it is recommended to strictly disable this service, otherwise collisions might occur and WinRoute may work incorrectly. It is also recommended to disable also other system services which might cause collisions — Universal Plug and Play Device Host and SSDP Discovery Service.
In the final stage of the installation, the WinRoute's initial configuration wizard is started where you set administration username and password.
Under usual circumstances, a reboot of the computer is not required after the installation is completed (a restart may be required if the installation program rewrites shared files which are currently in use). This will install the WinRoute low-level driver into the system kernel. WinRoute Firewall Engine and the WinRoute Engine Monitor will be automatically launched when the installation is complete.
