Subject is intact.

I found something interesting while trying to perform a process.
To be filtered by the ICMP protocol, where the ACL and Firewall, was that you should not use it.

But no matter how these ideas to Google, there was no answer to this.
Please share reference about this or more keywords, and your knowledge.

you are not clear on what you are trying to do.. 

 

You want to block all icmp without using access-lists? 

 

I think an intrusion prevention system is a very expensive solution for this.. 

 

technically any device that can drop traffic is a firewall. So I don't see much other option for you. You could use a linux box running ip tables to do the same thing however that is still a firewall..
