I have been using FreeBSD for almost 5 years, and lately because of the several attempts to penetrate my system, I have set up ipfw to restrict access from the outside to my network. Everything is working quiet well, but I am getting the following log from ipfw several times: server /kernel: ipfw: 65435 Deny ICMP:8.0 213.142.81.223 64.4.13.33 out via tun0 I have been able to understand most of the logs, but this one I just understand that ICMP is trying to send something out to server 64.4.13.33. but it is saying ICMP:8.0 What that means ? And why should my server initiate connection without my knowledge ? Thanks in advance for any information...
