<blockquote><p>No!!</p></blockquote>
|

<p>A blanket block of ICMP on your network device breaks some important features like ping, traceroute, MTU discovery, and the like. MTU discovery (Fragmentation Required) is especially important, and ignoring it can cause connections to appear to time out for no obvious reason.</p>
