A little background
In the past I have used devices that have single port forwarding which has worked fine for me.
I know have a device that only has port range forwarding.
I have 4 Devices that have a service that runs on port 3000 connected to my modem. When I access my public IP I want to be able to access all four devices.
If I have a public IP xxx.xxx.xxx.xxx
Device 1 - Port 3000->3000 - 192.168.1.10
Device 2 - Port 3001->3001 - 192.168.1.20
Device 3 - Port 3002 ->3002 192.168.1.30
Device 4 - Port 3003 ->3003 192.168.1.40
when I try to connect to xxx.xxx.xxx.xxx:3002 from the internet will it open port 3000 on the LAN side on 192.168.1.30?
