The return message's TTL is set by the terminating router when it creates the packet, and decremented normally. Traceroute would show you where that problem is. Remember that by default, the traceroute will send three packets to each hop. That first router in the path will still decrement the value by 1, but because the TTL will no longer drop to zero right out of the gate the packet can live on for one more hop. This is often referred to as latency, and is the same number you see when using ping. With details of the first hop in hand, traceroute will increase the TTL value to 2.
