    Hey all

    If I am running a home network with internet access through a wired/wireless router with NAT (acting as the DHCP) and then through the DSL modem (acting as a DHCP for the router to drill down the IP even further)..... do I need firewalls on the PCs?

    I use strong WEP and do not broadcast the SSID on on the wireless. I also limit the DHCP to only the min # of IPs I use. I use Mac address authentication as well. Of course, I do run AntiVirus and AntiSpyware.

    I would like to avoid the redundant protection if possible. Plus my wife and kids don't ever know what to do with the firewall prompts, making it a pointless adventure.

    PS: my network has the following:
    5 PCs. 1 Server. 1 NAS. 2 Tivos. 1 Xbox 360 (with media connect enabled on some of the PCs).

    Thanks!
    ~ Dad

    You already have one of the best firewalls against incoming attacks that you can get.

    You only need another firewall if you feel that you need outgoing protection; e.g., from spyware "calling home" with your passwords and financial data. I don't feel that I need one for that purpose, but I cannot do your risk assessment for you.

    I'm with Terry, I don't have any other firewalls, I trust my router. :) I'm also pretty restricted in how I use the Internet, so I'm what you call a "low risk" user.

    I have to agree with the NAT as well. Never had any issues. Unless you have multiple public IP addresses on your network I wouldn't worry about the personal firewall. If you did have multiple public IPs a hardware firewall would be in order.
