    Hi

    I suppose those three words usually go together. Complex Network and Problems! I'll explain the situation.

    I have a total of 12 networked devices in my home (maybe more! - Wireless only though)

    2x Wireless N Laptops
    5x Wireless G Devices (Laptops,etc,etc)
    5x Cabled (1GbE)

    At the moment my network looks like the following

    30mbit Cable Line > Wireless Router > Switch > Computers

    Im adding the following in the next week

    1x 16port Dell Managed Switch
    1x Wireless N ADSL2+ Modem
    1x ADSL2+ Line
    1x New System, Wall-E2 with Dual GbE
    1x New System Alexa with Dual GbE

    My objectives are:

    - Create a Wireless N network that draws from the 30mbit cable line. NOT the ADSL2+
    - Use link Aggregation between Wall-E2 and Alexa. (Yes! I've researched this aplenty, and i've found a software solution to take advantage of the multiple links when transferring files. (in this case different VMWare sessions)
    - Provide the ADSL2+ Line to ONE system only used for bit-torrent, (though other computers being able to use this would be an advantage)

    Im looking at creating this:

    Solutions (So far!)

    - To access Wall-E2's ADSL2+ connection from any computer I was thinking about using a VPN

    For me this is all a learning experience, and any help, websites, crazy idea's I would love to hear about and further investigate!

    Thankyou in Advance!

    Hi,

    You're going to need a router for such a complex routing scheme to work. You're going to need to make one or two changes to the architecture, but the idea will be the same.

    If you're on a budget, take a look at OpenBSD (specifically read up on CARP -- see if you dont think it would make a nice addition to your diagram with 2x cheap / old boxes).

    If you're not on a budget, 2-3 hours of a good network consultants time will a) get you setup b) teach you how to do this for life

    Disagree with above, piece of cake.

    1. Disable DHCP on your "torrents only" line.

    2. Set your "torrents only" workstation to have a static IP and default gateway to your ADSL router.

    3. Set the rest to static with default gateway of your Cable router, or DHCP to it.

    4. On the Dell switch, you'll need to configure "channel-group X mode auto" or "mode on" in two or more ports, to create the virtual interface for the port channel.

    5. VMware ESXi 4.0 is what you're thinking of using? If you've not had much experience with this I can tell you it'll do what you're expecting. Just make sure you set every vSwitch to use "Route By IP Hash" or "Route By MAC Hash" for compatibility with Link Agg.

    Your workstations will only use the default gateway if you leave the subnet. By putting all your devices in the same subnet, you won't need to do anything special to have your torrent box and torrent ADSL working on a dedicated WAN link while still being able to contact your LAN.

    Even your wireless N to cable will work fine, as they'll pick up DHCP from your cable router. That or give em all static IP addresses.

    If you wanted to link aggregate your WAN links, you would need some specialist kit, but it does exist.

    It would only be outbound aggregation, but that seems to be what you're after. For inbound, you'd need a BGP feed from your ISP, which no-one would do on ADSL or cable :p

    You can manually failover with this solution by changing the default gateway IP, or you could pre-prepare a batch file on your desktop which will change your settings using the "route" command line program within Windows.

    oh my lord, you prize bit-torrent so much your installing a 2nd line for it just so your web browsing isn't effected.

    Truly mad!

    This is what I am describing.

    [​IMG]

    You can only have one DHCP server per broadcast domain.

    By connecting the two routers into each other, via the Dell Switch, as long as you leave it VLAN untagged, you only have one broadcast domain.

    The normal process for a Wifi association is

    - Laptop associates with Wifi
    - Laptop sends DHCPREQUEST to FF:FF:FF:FF:FF:FF eg the whole subnet
    - The DHCP server replies

    That DHCP server doesn't have to be the wireless router itself :thumb:
