DNS server

I installed a DNS Server called Treewalk, and is able to redirect websites to my webpage in my computer. Even computers connected to my main computer will be redirected. I have disabled DHCP in a router connected to my main computer via LAN and turned on Internet Connection Sharing via dial-up with my GSM modem. Without the dial-up, there isn't an ICS in the LAN connection properties. Another method would be to install a wireless adapter and LAN will have the ICS option.
