If you want to offer web services on a PC at home or access your PCs from work or college, upload digital photo next time you visit your gran or even just set MythTV to record from your mobile/handy/cell/blackberry/fondleslab/whatever, you would need to open your BBR firewall to allow connections from outside in. Inside, on your LAN, you don't need any more firewall unless you are insanely paranoid. Unless you've been playing around with it, your broadband router's firewall will have only two rules: If you have a broadband router, it has a firewall, most probably iptables based.

I had a broadband router and it had all the firewall I needed but I still amused myself with the firewall software discovering just how many Windows applications needed to access the Internet without my knowledge or consent while I wasn't even using them. When I ran Windows and Windows firewall software I had a trusted zone - inside the house - and a untrusted zone - outside the house. The first needs a firewall, the others don't. In many homes a Windows PC is connected directly to broadband with other PCs in the house connecting through the first. In the bad old days of dial-up modems, your PC was connected directly to the Internet in the sense that the bad guys out there could probe your IP address to see if they could get in. I suspect there is a misunderstanding of the need for a firewall here. In my copy of Knoppix 6.4.3, there is a menu choice under 'Preferences'Ĭalled 'Knoppix Firewall'.
