Since enabling (but not yet using) firewalling in the 2.4.1 kernel, my log gets clobbered with messages like: Feb 1 12:58:56 obelix kernel: NAT: 0 dropping untracked packet ce767600 1 129.69.22.21 -> 224.0.0.2 Feb 1 12:59:01 obelix kernel: NAT: 0 dropping untracked packet ce767480 1 129.69.22.21 -> 224.0.0.2 Feb 1 12:59:04 obelix kernel: NAT: 0 dropping untracked packet ce767d80 1 129.69.22.21 -> 224.0.0.2 Feb 1 13:00:44 obelix kernel: NAT: 0 dropping untracked packet ce767600 1 129.69.22.51 -> 224.0.0.2 Feb 1 13:00:47 obelix kernel: NAT: 0 dropping untracked packet ce767600 1 129.69.22.51 -> 224.0.0.2 Feb 1 13:00:50 obelix kernel: NAT: 0 dropping untracked packet ce767b40 1 129.69.22.51 -> 224.0.0.2 The IP Adresses belong to Windows 98 computers. What does the message mean, and what could I do to stop them?
