Subject: change in behavior of OUTPUT chain rule in 2.6.19
Date: Thu, 14 Dec 2006 13:30:01 -0500 [thread overview]
Message-ID: <45819829.2060806@laurelnetworks.com> (raw)
Between 2.6.18 and 2.6.19 (and 2.6.19.1) we've observed that a reject
rule on the OUTPUT chain no longer causes a connection attempt to abort
immediately with "Connection refused". As a specific example, this rule
iptables -A OUTPUT -p tcp --destination-port 23 \
--destination 10.0.20.1 -j REJECT --reject-with tcp-reset
will cause a telnet connection to 10.0.20.1 to fail immediately under
2.6.18 but will take minutes to timeout under 2.6.19. Is this an
intended change in functionality or a regression? This is all using
iptables-1.2.7a.
