Is there any protocol for reverse traceroute?
Say i'm communicating with a computer A in a remote network .

Is it possible to know what are the hops that he is going through?

In other word, is it possible to detect what is computer A route to my computer?

I know that A might have a various routes to my computer , it just want to find a route. My whole problem begins with that fact that some networks  "hides" there inside computer ( like NAT ) and just give you the gateway ip.

(I'm not talking about my route to his computer that can be easly achived by traceroute)

thanks!
