[Shorewall-users] Unknown commments in shorewall status.
I wonder if someone can tell me what these ''unknown'' remarks mean in my status file. They are only in the last portion of the file and are listed below. If they mean nothing, I will rest easy. But if not it means I need to fix something. Your thoughts would be appreciated. ---------------- udp 17 92 src=24.224.173.220 dst=24.222.0.75 sport=1027 dport=53 src=24.222.0.75 dst=24.224.173.220 sport=53 dport=1027 [ASSURED] use=1 unknown 93
