Mangle table,what is that?
I am trying to find what is and what for there is tha mangle table.
The only inforamtion which i found is only from manual.
mangle This table is used for specialized packet alteration. It has two built-
in chains: PREROUTING (for altering incoming packets before routing) and OUTPUT (for altering
erated packets before routing).
This is used to set the 8-bit Type of Service field in the IP header. It is only valid in
the mangle table.
You can use a numeric TOS values, or use
iptables -j TOS -h
to see the list of valid TOS names.
And i can not figure out anything:(
For a example, when the manual say about altering the incoming packets what it tries to tell me?
I just want to know because i am building my firewall and i don't know if i have to leave the policy
as it is
or to set DROP policy and if i have to do add rules for this table.
This table has to do anything with security?
This is the question.
THanks in advance,
I love having the feeling of being in control
