I have attach a diagram of dmz setup using a cisco soho router, cisco IPS, cisco asa. I want to know how i can stop an attacker. currently from IPS i can block a host. But even i block the host from IPS, i still get alerts from that attacker IP address. I think its because even I block that attacker from IPS that attacker still can reach IPS interface before getting droped.This can still cause our hosted services to be down. So isit possible i can block the attacker IP address from the router and then IPS and at last from ASA? In this way there will be slight chance of success for that attacker. And our hosted services wont be down.
IF so how can i add a rule to block a attacker ip address on cisco soho 78 router and then ASA?
