Hi Guys and Experters.
Normaly I don't buy firewall to protect my dedicate server b/c i can lease from my hosting provider but now I moved my server to colocation near my place so i can have a hand on expericense.
I have 3 ips address which i received from my colo providers.
They are not private ip address
77.xxx.xxx.15 and 77.xxx.xxx.16 and 77.xxx.xxx.17
My web hosting server IP is 77.xxx.xxx.15
My IPS-4255-K9 management port is 77.xxx.xxx.16
Can you guide me step by step to set it up properly so my IPS can block all DDOS / SYN attack traffics and the good traffics can go to my webhosting server port 80 77.xxx.xxx.15
