Hi,

 

We have a cisco ASA1001 and a Cisco 1921 router on a network.  The ASA currently passes traffic through it from our ISP to the 1921

 

All interfaces have have public IP addresses. What is the best way to block certain source IPs from either hitting the Cisco 1921 or blocking them completey?
