Solution
The INPUT chain specifies changes to packets as they are processed, but after the PRE
ROUTING chain is traversed.
The POST ROUTING chain specifies changes to packets as they are exiting the firewall, after
the OUTPUT chain is traversed.The FORWARD chain specifies changes to packets that are
forwarded through the firewall.
The OUTPUT chain specifies changes to locally generated outgoing packets.
information is available about packet marking in the iptables documentation, beyond that it’s
used by the Linux Quality of Service implementation and that it’s intended as a communication
flag between iptables modules.
Scenarios and scenario techniques are also distinguished by the type of information which they
can and should assimilate and/or transport. Are qualitative descriptions alone used r the
generation of scenarios depending on whether quantitative or qualitative data are required,
meaningful, and available. Quantitative knowledge is used, for example, in topic areas like
demography and economics, whereas on the other hand cultural, institutional or political
dimensions often tend to be recorded qualitatively ,The methodological decision for proceeding
either qualitatively or quantitatively has direct consequences regarding the possible degree of
formalization of the scenario technique to be used. To put it provocatively and ideal-typically,
quantitative approaches have recourse to mathematical models, qualitative approache on the
other hand have recourse to narrative and literary techniques.
