I have a cable Internet connection and run it through a Linksys router. This has NAT built in for protection. Of course through this I run DHCP to three other machines in a home network, 1 linux and 2 wins. Is this good enough or do I need to setup a personal firewall besides. I have Suse 7.1 and don't have the personal firewall on as this is the way the auto setup did it through Yast. If I do turn it on will this throw a monkey wrench into the something that is running fine now. I'm a newbie at firewalls and the option of just having it done automatically seemed appealing. But I figured Yast has to be much brighter then me and it had to be a reason. I'm thinking because of the DHCP?
