Hello!
Could anybody explain about one way to filter SYN (I found it in MikroTik Wiki):
/ip firewall filter add chain=forward protocol=tcp tcp-flags=syn connection-state=new
action=jump jump-target=SYN-Protect comment=“SYN Flood protect” disabled=yes
/ip firewall filter add chain=SYN-Protect protocol=tcp tcp-flags=syn limit=400,5 connection-state=new
action=accept comment=“” disabled=no
/ip firewall filter add chain=SYN-Protect protocol=tcp tcp-flags=syn connection-state=new
action=drop comment=“” disabled=no
What does mean in this rule limit=400,5?
Thanks a lot!
