If you want to completely flush all IP table and reset to an open firewall state, you should set the
accept policy on all exchanges, flash all net filter tables and delete all IP tables, user defined.
James, if there is any, this is useful to use at the beginning of any final script in order to flush
everything and to build it from the ground up.
I'm creating a script named Delete Firewall that S.H..
The first step is to set the except policy on all the change of the filter table, their input output
and fought for change is used only for our allotted packets.
And that means that the Linux machine has also the function of our KRAEUTLER.
IP is minus B input, except IP table is minus B output, except.
And IPT is minus B for art accept.
The second step is to flush all tables that have Ruelas.
IP table is minus the filter, minus F IP tables, minus the net, minus F IP table, minus the main
goal, minus F and IP table is minus the Harrar, the last table minus F.
If the table has no goal, nothing happens.
And lastly, delete the user defined chains, if any.
This is optional and the needed only if there are user defined chains will talk about user defined chains
in another lecture.
IP table is minus X if you are using IP set to drop large collections of IP addresses like entire countries.
You should also flush and destroy the six.
There will be a dedicated section about IP said later in the course.
OK, that's all.
I am saving the script.
Then I make it executable and run it.
The IP table is Firehole has been cleared out and all traffic is permitted, by the way.
This is also the default state of a Linux operating system.
