I am trying to setup the network for a small business using a network configuration I am new to. The business has one public IP(135.x.x.x) and wants to use separate machines for its website (www.example.com on 192.168.1.50) and sharepoint site (sharepoint.example.com on 192.168.1.75). The DC is on 192.168.1.10
I have added DNS Host A records for the sites pointing to the private IP address of the hosting machine. From inside the LAN, all users can access the web and sharepoint sites. But from an external PC, the websites return a 401 error.
Not sure whether my problem is topology, DNS, firewalls, or if the concept is simply not possible with only one public IP.
