So, I have the ASA 5505 Firewall. I generate an ACL to block three IP. Those IP are from outside and are generating fraffic with an internal server.
After aome hours I still get traffic from those IPs as you can see in the nex image:
The IP 18...
Actually I think I get it now. It was working coming from outside. The problem is the traffic initiated from inside. I'll add an ACL outside (outgoing rules) to make it work. Thanks.
