Configuring Mikrotik for Firewall Mangle Part 2

Configure the Mangle Firewall for Part Two

Hello everyone, I will give an explanation of the placement of the mangle firewall on Mikrotik RB750, but you should see my writing in the first section, and can see it here

What is Mangle Firewall ?

Mangle is a kind of 'marker' that marks packets for future processing with special marks. Many other facilities in RouterOS make use of these marks, e.g. queue trees, NAT, routing. They identify a packet based on its mark and process it accordingly. The mangle marks exist only within the router, they are not transmitted across the network.

Next I will display the firewall mangle menu

Then the mangle firewall page will appear, this I have filled in for a particular port path, then I will share the script for the mangle firewall.

Here's how to enter the script for the mangle firewall, you must open a terminal in winbox

The following is a script for the mangle firewall on winbox

/ip firewall mangle add action=accept chain=input dst-address-list=private-lokal \ src-address-list=private-lokal add action=accept chain=prerouting dst-address-list=private-lokal \

Enough here, for the next I will review about the next Mikrotik, I hope for support, so I continue to write next, thank you.
