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
