  1. I know that your supposed to only really have one firewall but I have my hardware firewall on my router and then a software firewall on trend micro internet security 2007. I was wondering if i should disable the trend micro one and just use the one on my 2Wire modem. And i was also wondering if its ok to use a hardware and software firewall without any interference.

    What you have is OK if you are happy with what Trend Micro offers. But you would never want two software firewalls.

    If the hardware router has NAT/SPI/Intrustion Detection/Internet Filtering by MAC/IP an etc/Parental Control, then you can get back with light firewall software like Armor2Net there are a few others that work for monitoring what's coming in and out. Some routers are full firewall hardware routers those are mostly found in VPN routers.

    Any NAT router + software firewall is ideal protection.
    It`s the NAT bit that gives routers the inbound security.

    add SPI.

    The recommendation to avoid multiple firewalls is ONLY a configuration and
    maintenance issue. It adds complexity and to ensure that data flows properly,
    they all need to be adjusted if ether is reconfigured. Ergo: use one and learn to
    configured it well.

    A hardware firewall appliance, as apposed to a simple router with NAT+SPI,
    is a great solution that most of us can't afford. Having one placed BEFORE
    a router is a great solution as it protects all down stream LAN connections
    with one common configuration. Without that, we opt for a personal firewall on
    each LAN system, trading more configurations to save $$$.

    btw: most routers used by home users should not be considered Firewalls, as the
    only firewall control that is available is port forwarding. A firewall normally
    controls protocols, source/destinations that are accessible, and ports which
    can be used, none of which are available on common routers.
