This won't be the most straightforward setup for someone unfamiliar with Edgerouters, but certainly not impossible if you're willing to play around with things a bit.
First off, it isn't possible to split off two pairs of ports into switched physical interfaces since there is only one switch chip in the ER-X. You could split two ports off the switch interface and bridge them, but that's a terrible idea for reasons (it'll kill your performance).
The good news is that you can do exactly what you want with VLANs. I won't go into every single detail, but here's a quick rundown:
-Run the WAN+2LAN2 wizard, making sure to create only 1 network.
-Add a VLAN interface on switch0 (for example, switch0.2
-Create DHCP server for switch0.2, add switch0.2 as a listen-on interface for DNS, and add it to any other services that need it (port forwarding, etc.)
-Enable VLAN Aware on switch0
-For your two ports that you want on your first subnet, set pvid = 1 (your untagged "native" switch0 interface)
-For your two ports that you want on your second subnet, set pvid = 2 (your new separate switch0.2 interface)
I'm sure I missed some steps in there, but read up on VLANs a bit to get comfortable with things, then start playing with it. It isn't too difficult to figure out if you're willing to read up on things and dig around the configuration a bit.
