Help converting three networks into VLAN

I had a problem with an appliance that only had one ethernet port because i need to connect it to three different network so i borrow an Dell N3024 switch trying to find a solution.

Already i have three networks cables:

- Network 1 (192.168.0.X)

- Network 2 (10.10.100.X)

- Network 3 (172.16.2.X)

The thing i want to do is connect Network 1 cable to N3024 Port 1. Network 2 cable to Port 2 and Network 3 cable to port 3. And finally the appliance to port 4. 

And now the problem, i need Port 4 have access to Network 1 as default (VLAN1), Network 2 as VLAN200 and Network 3 as VLAN300. So in the appliance i can configure the network card with an Network 1 IP (and no VLAN config) and then create two sub interfaces to use the VLAN200 and VLAN300.

It is possible? How can i do it?

Thanks (and sorry for my poor english).
