RouterOS Forwarding Protocols
1

Hi Guys ,

I have a dedicated server and have several IP In my dedicated .
I will use of mikrotik as router for my dedicated server and drop Attackers (DDOS) .
I know how can black an IP address In my mikrotik firewall rules .
But I will see how can Block an IP address for my special IP (dedicated ip’s) ?!!

For example :
I have 127.0.0.1-127.0.0.2-127.0.0.3 IP in my dedicated .
Attacker IP is 22.22.22.22 .
How can block attacker IP just in 127.0.0.3 ??!!

Use the forward chain for any traffic that is passing through the router.
