One more thing . If the packet is going to be forwarded and the TTL has value of 1 than the hop discards the packet . "A system should never receive IP datagram with TTL of 0 , but Net/3 generates the correct ICMP error if this happens since ip_ttl is examined after the packet is considered for local delivery and before it is forwarded" [TCP/IP Illustrated , Volume 2 - Gary R.
