Experts,
This is a two part question regardling VLANs on my network. The first part asks for your comments on my network design while the second refers to questions regarding DHCP addressing for end nodes on this VLANs.
I am redesigning my network infrastructure to accomodate a variety of needs:
1) Control and segregate networks (fobased on bandwidth usage and purpose)
2) Isolate networks for security reasons (viral outbreak, rootkits)
3) Streamline Voice and Data applications between internal nodes as well as between offices
In the diagram I mapped out a genereic setup of my home data center.
I've got a Juniper Firewall Natting Public IP Addresses for my internal LAN. Just behind that device is a Layer 3 switch to be used to segment traffic into mulitple VLANs for reasons stated above. I think I have this mapped out correctly except for a few key subnets
Notice how the Juniper device, the Switch and the Servers backbone all share the same subnet. The Juniper acts as the LAN gatway (192.168.15.1) while the Switch functions as a routing device between the LAN and WAN (192.168.15.2). But how about those servers? Is it wise to keep them on that same subnet? Here is where I could use your help.
Futhermore, I normally use Windows DHCP to pass out IP addressing to the local subnet. However, what's the recommended process in a situation where I've split my single network into multiple VLANS? How or where do clients get there DHCP addressing on their specific VLAN ?
Please comment and elaborate on past experiences. The more you can give me the better off I am in executing this design properly.
Thanks!
