    Which router do you have most have a built in firewall?

    routers use nat firewalls.
    not the same thing.

    Yes yes but since it blocks incoming connections reaching the pc in most cases it will do enough.

    routers use nat firewalls.
    not the same thing.

    I have a Netgear DG834G modem/router and it has a pretty useful firewall built-in.
    Control over incoming and outgoing ports, broadcastable logging, UPnP support, VPN support, DoS and Port Scan protection.

    More than sufficient for home use.

    I’d only bother with a software firewall if I was using a laptop and connecting via WiFi points etc where I don’t have any control over who else is on the network.

    HTTP404 – explain yourself. Why is a software firewall needed as well as a nat firewall in a router?

    Have used Zone Alarm for years….. but the recent version seems to be a complete nightmare. I’m running vista, and in the end took it off as it really was screwing it all up. ( can’t remember exact details, bit simply just too much faffing )
    I asked several IT people’s opnions, and also posted on here. General opinion being that our router + windows firewall seems to be sufficient for home use.

    Whilst NAT discards all unsolicited traffic received from the Internet, it does not restrict conversations initiated by the computers behind it. A software firewall (and it’s user) would theoretically prevent malicious programs from initiating these ‘outbound’ conversations.

    As I said, the firewall on my router does allow me to control outgoing ports. Granted it only does it by port as it can’t know which particular program is initiating the connection, but I agree with…

    Clearly, a software firewall employed as a security measure in this scenario should only be considered as a last resort backup against the subset of malicious code that is network-aware. If your existing measures against malicious code in general (common sense included) are up to scratch, a software firewall may well be a waste of both your and your computer’s resources. If they are not, you really need to make them so!

    As with all security measures, the decision to run a software firewall should be based upon an evaluation of the cost / benefit ratio. A software firewall uses memory and CPU time on the host computer, requires proper configuration, frequent user interaction and often produces false positives in (usually overly dramatic) alerts and logs.

    The router firewall is more than sufficient for me. I leave the built-in Windows Firewall running for some software-level protection, but I have no need to install ZoneAlarm, commodo etc.
