What I am trying to do I am not sure if it is even possible, I am trying to setup a testing lab in my house to have 2 vm host running server 2012 on to different subnets so this is how I want to set this up if possible and please tell me if it is not Coming from my modem plugged into pfsense firewall running 192.168.20.2 on the lan side From the firewall plugs into my Extreme switch x250e switch all untagged ports from here to my vm host my server 2012 r2 is setup as a domain controller, DHCP, and DNS on 192.168.20.1/24 this is all working fine , The problem is I have another switch that is a Dell power connect that is running another vm host On this server 2012 r2 is setup as Domain Controller, DHCP, and DNS running ip range 192.168.30.1/24 Is there a way to connect the Extreme switch to the Dell switch to pass traffic back and fourth on both subnets so I can access any other servers or clients on either subnet and Have internet running on both subnets running with 1 modem and firewall Any help would be great
