Subject: ESTABILISHED connections are not that estabilished
Date: Wed, 27 Jul 2005 18:10:15 +0200 [thread overview]
Message-ID: <dc8blc$p5s$1@sea.gmane.org> (raw)
In my logs I often find reports of dropped input packets from my DNS:53 or
dropped output packets generated from localhost:25 to other mail servers.
They look like these:
iptables INPUT DROP IN=eth0 OUT= SRC=69.93.28.254 DST=myIP LEN=70 TOS=0x00
PREC=0x00 TTL=54 ID=0 DF PROTO=UDP SPT=53 DPT=4156 LEN=50
iptables OUTPUT DROP IN= OUT=eth0 SRC=myIP DST=219.136.64.239 LEN=87
TOS=0x00 PREC=0x00 TTL=64 ID=44757 DF PROTO=TCP SPT=25 DPT=3062 WINDOW=5840
RES=0x00 ACK PSH FIN URGP=0
I thought these connections should be handled by
iptables -A OUTPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
and not dropped by the default policy. The logs show that this is not true.
Why are these packets dropped?
