[UFW BLOCK] in dmesg
by MilkTea from LinuxQuestions.org on (#5JXZA)
I have a rather strange problem that I couldn't figure out. On my server, I only enabled port 22 for SSH and port 6000 for an application. The default policies were deny incoming, allow outgoing, and deny routed. I noticed a bunch of [UFW BLOCK] from some external peers and the STP is 6000.
I couldn't figure out why ufw blocked those traffic, I changed the default for incoming to allow. Well, it didn't help. I then changed the default for routed to also allow. So now all incoming, outgoing, and routed are allowed. Still, I am seeing [UFW BLOCK] growing whenever I check dmesg.
I thought by allowing all is essentially not blocking anything. Why does ufw still block the incoming traffic?
