Can not see my own websites after setting up routing

I have setup counting on Machine1. It is connected directly to the Internet
as well as my local network.

I have websites setup on Machine2 on my local network and am routing all
traffic from Machine1 port 80 to it.

I have another server on my local network, Machine3 that I use as a
workstation.

When i attempt to connect to my website from Machine3
(http://www.domain.tld) I get the "Page can not be displyed". But, when I
connect from a machine out on the Internet, it works fine.

What have I done wrong?

Thanks
