Firewall considerations - 2 Dual boot PCs
I am in the process of setting up a 2nd PC (a laptop). Have wireless Router and card for the laptop. Regular PC will be base station. Both systems are dual boot, XP and Fedora on the Base, XP and Debian on the laptop.
Current firewalls on Base - Kerio for XP - IPtables for Linux. Router currently is simply 'Firewall enabled.' I don't think it's doing much except watching a couple primary use ports. I still use the software firewalls for specific rules, and they appear to be working fine. Laptop is not yet networked, and has no firewall software installed.
Question: (and a very broad one I'm afraid) What should be my primary planning areas for bringing the laptop online? Either computer at any given time could be running Windows or Linux. Is there any hope of maintaining software firewalls, or am I going to have to try to figure out how to enter all the rules from the software firewalls into the router?
