I have a Server (which needs DNS and Internet access) and a private network.
I'd like to have the devices that only need to connect to the server, stay on the private network and not be visible to the Public Internet.
The server still needs to talk to the devices on the private network and have Internet access through a router to process credit card transactions.
Is this the correct architecture and do I set my Router as the Gateway at my Server PC or only program in the DNS settings? Can I keep my Server on the private network 192.168.10.x and Gateway at 192.168.100.x? How will the server be able to reach the router on a different subnet? (I have only one NIC in the server)
