I have more than a few computers behind my home wireless router which only has the most basic firewall. I also run Windows 7, OSX, Ubuntu so trying to buy firewall software for each OS and running machine is going to require too much maintenance.
I'd like to put something preferably before the router to manage all firewall aspects but I'd also like it to have a webpage I can hit for reports/alert management etc. If I can put it between the router + cable modem then the router can still act as DHCP/Wireless etc.
I have a Netgear WNDR3300 - not sure it has enough firewall features to be much use and no easy management/log of what is going on. It's not DD-WRT compatible.
The concept I'm shooting for is what you'd get if you purchased a personal firewall product to install directly on your machine - those alerts and intrusion attempt reporting are great.
