Using only my Box (FTTH), I’m able to access my home network (box Lan subnet) by simple NAT redirection from any internet location. More precisely, I connect to as many hosts, residing in my home network, as redirection rules on my box.
My box supports only an overload NAT of my inside local addresses. If I access my network from the outside using my inside global routable address , internet, using my unique public address, I have only the possibility to redirect application port to a local port and address that belongs to the subnet, clients, connected directly to LAN ports of my box, use to access internet.
