I have this rule: $IPT -A INPUT -i ${PUB_IF} -m state --state INVALID -j DROP The problem is its matching legitimate packets of visitors (including me) that navigate my site... As i can see in the logs. Its not affecting the normal viewing of my site.. but I wish to know why it is matching these packets as Iam sure it should not. Here is the log entry in syslogd Mar 16 15:29:36 kernel: Invalid IN =eth0 OUT= MAC=00:16:3e:44:bf:02:00:11:92:8b:ff:c4:08:00 SRC=xxx.xxxx.xxxx.xxxxx DST=xxxx.xxxx.xxxx.xxxx LEN=40 TOS=0x00 PREC=0x00 TTL=47 ID=0 DF PROTO=TCP SPT=6367 DPT=80 WINDOW=0 RES=0x00 RST URGP=0 Thanks Mike -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
