We have a Cisco 1841.
Fast0/0 with 188.8.131.52 (IP to ISP)
FAST0/1 with 184.108.40.206/27 (our public ip block)
I like to specifically block any incoming (from internet) access from port 1-1024 to only 220.127.116.11 (one of our public systems)
How can I do that?
I have tried:
access-list 101 deny tcp any lt 1025 host 18.104.22.168
the moment I apply it to either fast0/0 or 1, it cut all access. could someone help?
Thanks in advance
