    How to block country ip ranges without overloading the router

    acl New Member

      Hello All..

       

      I have a mail server that is under attack by spammers. I would like to block all country ip ranges except for those assigned to the US. The problem I see is that you can't create an acl that big without killing the router. So is there a way to craft an acl to accomplish this task?

       

      Any help appreciated.

       

      Thanks!
