I would like to point out that I am not wrong - Mr. K6. There is really no absolute right or wrong when it comes to how to configure a PC for security - rather it is a matter of opinion. And one's opinion is based on how comfortable they are with technology, what risk they are willing to accept, how many people are using the LAN in question, etc. When behind a router with SPI firewall on my own private LAN (where I am the only user) I simply don't feel it is worth the overhead of running a software based firewall. There is "some" overhead (granted it is very slight) plus there is configuration management for certain applications such as hosting a gaming server, peer to peer, etc. I perfer to keep this sort of configuraiton tied to my router. In some ways a firewall router can be superior to a software firewall as the router is basically its own device with a CPU, operating system, software, etc. - and as such it is not suseptible to the standard Windows based viruses, worms, etc. that a software firewall could be impacted by. Now granted running behind both the router firewall and the Windows firewall does give you some protection, but at this time I don't feel it is really needed with my current configuration.
