    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).

    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.
