We've just switched from router to just plugging our cables straight into the modem. I suspect this means that I have no router firewall. However, I've encountered a situation where I need to open ports to get an application to work, and I don't know how to do that now that I don't have a router firewall. I'm useing the free edition of Zone Alarm.
