Setting up Secondary Subnet with Remote Access to my Lab

Hey all.  I'll try to keep this brief and to the point while being detailed. 

I setup a CCIE home lab and I setup 4 Cisco 3560 switches as i'm going through some L2 labs.  My home network is pretty simple.  I have FIOS coming into our first floor and use their modem/WAP.  I have all of my equipment in the basement.  I have a Linksys AP running DD-WRT in the basement that is acting as a repeater for my WLAN, and all of my equipment goes into the ports on that AP. 

Out of no where, I started receiving duplicate IP messages on my computer and it was driving me nuts.  I narrowed it down to my switches.  When I unplugged the main copper from the Linksys AP in the basement, everything started working fine.

Rather than trying to figure out what is causing this issue, I think it'd be easier to segregate this from my regular /24 that i use throughout my house.  I just don't know how to go about doing this.  I never setup a DMZ or anything like that (nor am I opposed to it), but I'm just curious what is the best way to go about setting this up. 

With these switches I have a Dell T620 running VMware with 20 virtual routers.  It also has Windows Server 2k12 which has DuckDNS on it which is what I use to get me remote access.  My thought is to take this entire environment and segregate it from my regular network.

Any ideas would be appreciated.

Hello Michael,

do you have a schematic drawing of your setup including your current IP addressing ? We need to get an idea what you want to separate from what...

Hey Georg.

I don't unfortunately, but hopefully I could describe it best as possible.

The FIOS feed coming into the first floor goes into their modem/WAP.  This has the network for all of my home devices.  

Downstairs is all of my cisco gear.  I don't have a feed from Verizon down there so I took an old Linksys WAP and I set it up as a repeater bridge with my current SSID, thus, I could use the 4 ports on the back of it.  This Linksys WAP uses DD-WRT.

I figured I could segregate these ports and create a separate VLAN -  I followed some tutorials on dd-wrt sites but it doesn't seem to work.  I'm thinking because maybe its set as a repeater?  I'm not sure.  

I hope this helps.
