Hi, From RFC792, Type 11 = Time Exceeded Message Code 0 = time to live exceeded in transit Every time a packet passes through a gateway the TTL value is decremented by one second. When it reaches zero the gateway must discard the packet and may then send this ICMP message back to the source host. But read the rfc.
