I'm interested in installing a host firewall and perhaps an IDS for the laptop I use for school. I am wondering if there is some tool that can help me to understand the current firewall rules. Something as simple as iptables --list would be a starter, but if this uses a more complex ruleset, I do have some experience with firewalls and IDS as well.
Sorry for the late response here, but I wanted to check in to see if you were still having questions with this and to see if you needed any input or if you already had found your answers. If you still need help, let me know and I'll be happy to work on this with you.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
