Subject: State NEW and --syn flag
Date: Tue, 20 Jul 2004 11:15:39 +0200 [thread overview]
Message-ID: <TBEXEDU01kJSFsxf4yp000000d3@smtp.maurickcollege.nl> (raw)
Hi all,
When writing a rule, if one doesn't specify a state, state NEW is
assumed, right ?
If the first packet of a connection arrives, it has state NEW and
subsequent packets are ESTABLISHED or RELATED. The first packet also has
the --syn flag set so new packets could also be identified by --syn.
If checking for state NEW, is there any reason to also check if the
--syn flag is set or is it enough to just rely on state NEW ?
Gr,
Rob
