I need a suggestion / guideline for a solution. In Cisco Router we can define Access List, and based on this we can filter packet based on source address or destination address. Is it possible to store this access list source and destination address in separate database/server. I mean, in router I indicate the server from where router will fetch the source and destination address. And in the server I will store the source and destination address. Every time router will compare the list from the server and drop/pass the packet based on the list.
Is it possible?
