Is there any truth in the rumour that if you have a router between your modem and PC, then you don't need a software firewall such as Zonealarm etc?
My router's a Netgear WGR614v6. According to the Netgear site it has 'Double Firewall protection from external hackers attacks'. I'm more than a bit reluctant to knock my Sygate firewall off. All the software firewalls I've tried prompt for permission for programs trying to access The Net. I'm wondering how the router performs its function without the prompting.
Router firewalls block incoming threats but not outgoing (ie if some malware is on your computer and is trying to send data outwards). So a decent software firewall is useful as they stop incoming and outgoing threats. If you aren't too worried then the router firewall and the simple XP firewall will do a decent job stopping incoming traffic. But look at ZoneAlarm and Comodo's Firewall (both free for home users) to add the extra protection for outgoing traffic.
