I would like to know if it's possible to achieve a traceroute of nodes on an internal network from an equipement on the internet answering to a query.
Let's say that a client on an internal network send query to a server on the internet, http server for example.
Is it possible for this server to achieve a traceroute by sending serveral time its response, starting with a TTL of 1 and incrementing it for each response ?
From my point of view, packet should be accepted by the NAT router of the client and redirected on the internal network because it's a response. And so, it could be possible for the server to get TTL expiration responses and IP address from the internals nodes.
