    yes - excluding DC I'm not understand what the other abrievations mean and also can't see where the firewall sits and you have a number of things off of one branch ( presumably cable )

    Was hoping for something a bit more detailed / in depth so I can see where you would connect the firewall to and what the proxy connects ie

    So Router from ISP --> firewall ( whether software or hardware ) --> proxy server --> VPN --> ?????

    Don't know how much this will help, or confuse more, but this is a (very) rough layout of our current network topology.

    That's more like it - just a few things

    * Which physical server are the virtual servers running on ?
    * SMB Folder shares is that a SAN or NAS or something to that effect ?
    * VHD Access switch - what is this and what does it do / what is its purpose etc ? I thought VHD meant Virtual Hard Drive
    * DMZ Switch - Is this an actual switch that is configured to place certain servers / items into the DMZ ?
    * How come the smoothwall utm ( which deals with vpn / proxy / firewall etc ) has 2 connections into the DMZ Switch , they aggregated links or because said device deals with so many roles ie proxy / vpn / firewall etc so needs the extra connections ?


    I presume the smoothwall UTM deals with all the different roles so proxy / firewall / vpn etc

    Everything in the diagram is physical. So there are three individual physical host servers. The square brackets underneath give an indiciation of individual running virtual machines.

    Technically I believe it qualifies as a NAS set up in a SAN-like configuration.

    This is the network route virtual machines hosted on the virtual servers take to access their virtual hard drives stored in a SMB share on the file server.

    Physical switch on the "live internet" side of the firewall. Anything plugged into it has a live public IP address.

    * How come the smoothwall utm ( which deals with vpn / proxy / firewall etc ) has 2 connections into the DMZ Switch , they aggregated links or because said device deals with so many roles ie proxy / vpn / firewall etc so needs the extra connections ?
    2 routers, each with thier own 14 address subnet. One link to each subnet from the smoothwall. Allows the smoothwall to provide loadbalancing and failover between the two routers.

    Yes

    Yes
    I would be interested in how the VHD Access Switch works to allow the different virtual machines / servers to access there relevant virtual hard drives stored on the SMB Share / File Server or is it just like vmware fusion etc where you have a profile for each virtual machine / server and in that profile it has the config ie which virtual hard drive said virtual machine uses and it points to the relevant VHD ??

    That's a good one - nice and simple / concise to understand

    Thanks @plexer

    (fake IP's)

    Core Network addresses - 10.95.32.0-10.95.33.255
    VHD Network addresses - 172.45.28.0-172.45.28.255
    External IP addresses - 229.39.174.28-229.39.174.42

    SMB File server has 2 IP addresses. One on core network (10.95.32.16) which users use to access shared folders (\\10.95.32.16\home$\%username%). The other on the VHD network (172.45.28.10) which virtual machines use to access their disk images (\\172.45.28.10\VHD$\PrintSvr\).

    Both connections use 2x1Gbps bonded pairs and TOE (TCP/IP Off-load Engine, less CPU load) nics. The VHD network uses Jumbo frames for faster data transfer.
