Port knocking is a mechanism to secure a network device by closing all the ports-even those you know will be used. Those ports will be opened on demand if-and only if-the connection request provides the secret knock (prearranged pattern). Port Knocking is one layer of security, it MUST NOT be our only form of defense

Great! Thanks for sharing. Very well explained! Cheers from Mesi's City - Rosario - Argentina!
Glad you enjoyed it!
perfectly explained. Thanks
Excellent Tutorial!
Glad you liked it!
GREAT VIDEO!!! tks
Thank you for the video. Unfortunately there is no option to set port knocking "action" as "run script". IMHO, it will be extremely useful in many use cases. Maybe you know some workaround how can I force mikrotik to run script after successful port knocking?
I use that PK but have additonal rule who detect any knocking into range 6000-9000 (without my 3 ports) and I block that IP at 1h. This is used when I cannot connect from trusted constance public ip. This prevent me from that knocking automatics.
Very good. Could we have the Eve-ng project file? Thanks
porque en la 7.15.3 no aparecen la src address list en advance
