Two networks w/ one dsl router

[Zemi]

I just started attending MCSA training and want to set up a test network in my home. I currently have two PCs connected to a switch that is then connected to a four port DSL Router. The DSL router is acting as a DHCP and providing IPs to my PCs.

My question is: What would I need to do to connect two different networks to the one DSL connection? These two networks would be independent from one another.

did you want the test network to have internet too?

Yes. I want both to have internet connectivity. Would I simply plug two switches into my DSL router and use a different workgroup name for each group?

if you just used a different workgroup name they would still be the same network, you can browse other networks besides the one your computer is on.

To segment your network you could assign your home network the default DHCP from you router (192.168.1.1-255) and your second network manually set the ip's to 192.168.2.1-255, but then your gateway would still be the same(routers ip).

Also why do you need this network seperate?

I leased a second IP from my provider and used two routers hooked to a switch that was then uplinked to one cable modem. The WAN IP of one router used one IP from my provider and the other IP went to the WAN port of the second router. The two internal LANs of the routers were different. The extra IP was about $5/month. And of course there's the extra expense of a second router. But it gives you two entirely separate networks that won't even share the same external IP.

I would like to have a separate network to practice security and other features on. Maybe I don't need to, but what the heck I'll learn a lot.

I think I will contact my ISP and see how much an extra IP address costs and go from there. Un less anyone has any other thoughts?
