    Hey,

    I am trying to re-configure my home network to allow for a secure and normal (not to secure) networks, that will not be aware of each other but will both connect through to the same router for Internet access.

    Basically I want one network that will be used only for Online banking, other important transactions and store important data and another which will be used for random web browsing,web mail, games etc that are more likely to get Spyware or Viruses.

    The two networks will only have a few computers/laptops on each network and obviously as this is for home I want to know if this is feasible without spending huge amounts of money. If anyone sees any problems with my thinking or has any advice please let me know.

    Am I correct in thinking that all I need is 3 routers?
    1. Wireless ADSL Router connected to phone line that receives Internet.
    2. The secure network router that connects to 1 and several computers.
    3. The standard network router that connects to 1 and several computers.

    2 and 3 would each have a separate wireless SSID and workgroup and use DHCP within different ranges to allocate IP's to the various computers.

    Is there anything specific that I would need to do to the routers configuration to get them to work?
    would the ADSL router need DHCP as well?
    Will I need to configure different subnet masks?

    Any help regarding this is much appreciated.

    Regards,

    Nnahrino

    That will work. The secondary routers need to have a different subnet from the primary router. It doesn't matter if the two secondary routers use the same subnet.

    Not sure how you are using the word "secure." I would advise WPA-PSK (or WPA2) on both wireless networks.

    Actually, two routers will work for this scenario.

    The first one that connects directly to the Internet connection and is the "standard" network connection.

    The "secure" router WAN port is connected to a LAN port on the "standard" router and allows for "secure" connections and separation from the "standard" network.

    No reason to have three routers that I can see.
