I get a kernel panic whenever I try to filter an unbounded number of packets, but it doesn't when filtering a small amount of packets. The things to do now are: - Test that the emission of all the new rules is working properly, and test that rule. - Avoid kernel panic. This will take a longer time, but we need this in order to get the firewall working in real-world systems. - Write flow modifying rules: Given that I've been out of the game for so long, I haven't been able to get those rules written yet, but luckily they are only two rules, and its implementation shouldn't be hard.
