Ok this is my first time I've ever sit up a firwall using linux. So far this is what I've done. I went to system settings selected security and choose what leve of security I wanted to implement. Then I chose what services I wanted to pass through the firewall. My question is what else is there left to do. First off I would like to know how do I enable another nic as a trusted device. I ask this question because I have 3 nics in the box. During the install you can choose what nic you want as a trusted device, but I have not been able to find out how to enable a nic to be trusted after the install.Also can you configure rules for the firewall if so how is this accomplished. And my final questionis can a dmz zone be set up using linux.
