I need a firewall to go on my laptop running windows XP, normally I would install Kerio 2.15, but it has some issues with being suspended and such. All of the firewalls I've looked at so far do not meet my needs, their do not offer a simple and clean interface which allows highly customisable rules. I have narrowed my choice down to Tiny and Look 'n' Stop and I want to ask a few questions to help in my decision: 1) Kerio 2.x loads the ruleset into memory from startup, and uses that as a trusted source, at shutdown it replaces the version on the hard drive with the version from memory to stop rule tampering, does Look 'n' Stop do something similar ? 2) Can someone explain the reasoning for splitting the application based rules from the other rules ? 3) Is their a roadmap in place ? I know that most commercial companies do not release their roadmaps, and this is one of the reasons I like open source software so much. But I like being able to see what the future holds.
