I started out trying to setup a Unifi Security Gateway to do this and gave up.
Now I am using an EDGEROUTER LITE.
I have 5 Public IP's.
I have 15 Ring Central VOIP phones. They are on VLAN3
I have a web server that is live on the INTERNET through one of my public IP's on VLAN2
On the main network:
I have a domain controller with the Microsoft Essentials Experience running.
I have an Exchange Server.
I have 15 Client computers.
I have SNAT and DNAT rules so that the web server, the essentials experience, and the exchange server, are all available from the internet via their own public IP's.
I can access the essentials exerience and the exchange server from the main local network with their Public IP's.
I cannot access our web server on VLAN2 from the main network.
My config.boot file is as follows:
