A client is trying to implement a solution on how to block foreign IPs (non-US/Canada). They currently have a Juniper Netscreen firewall, but it does not seem to have any options to do this.
Client has complained couple of times of having a lot of junk packets from Russia, India, China, etc, and since they only conduct business within US and Canada, they would like to block all other traffic.
Is there any practical way of accomplishing this?
Thanks in advance.
