Sub-netting or Routing?

Posted on 2011-09-29
Last Modified: 2012-05-12
I need to setup another server (Srv2008) on the current network. At the same time I need to keep these to Srv separated from each other ( two different business) so I will create a new forest when I do a DCPROMO on the new Srv. Both Srv will have static IP address of the other ( I understand there are on same subnet)
I have to install programs like Backup exec and Panda Business on both and I see that it will create a problem, b/c when I try to install Panda it say that there is already a Panda Admin Panel install on the network, which is correct.
Here is my question.
Should I give the new Srv and IP address of and use routing on each srv to be able to communicate with each other? Or put the second Srv on a subnet? or by doing the above I"m I doing both? ( I think I am ) ( boht Srv have to NIC cards )
Never done anything like this before ,so I like to get some fee back on the matter.
Thank you all...

If these are two separate businesses you want to keep them apart. So use two different subnets and separate the two by using a router or set up vlans if you happen to have a layer 3 switch.
That way you can control what traffic to allow between the two much easier.

Never done it.

What kind of router? Are you using it already for anything? How many interfaces does it have?

It's a Cisco router,RV220W

While I know I can do a VLan ( never done it before ) I like to subnet the network that I currently have

Hi, I'm still here :)

I think you'll need both. Create a vlan for each subnet (vlan10= and vlan20 = The RV220W has only two ports, inside and outside (though the inside is a 4-port switch) so to provide two networks on the inside, use vlans.
