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?

Have you got any firewall between yo lan and internet? You need to open those ports if you have one because by default the firewall blocks anything from outside.

You need to configure your firewall to do the nating and map ports to ip addresses. Unless if you have 4 public addresses

The maximum rule count is 10.

The above is what i see. So my question is if i put port 3001 as an external port will it automatically open all the internal ports on the said ip address.
