Not really but I understand what you mean. What I need is an encapsulation/decapsulation IPv4-in-IPv6 solution but with specific needs. After browsing a while on the Internet, I'm sure that tun/tap driver allows me to do that.
Maybe I misunderstand tun/tap and tunnels in general but what I'm trying to do is simply to establish tunnel between 2 hosts.
So it's normal that when the ICMPv4 packet encaspulated in IPv6 from the client to the server goes through the server decap interface (tun64), I expect that tun64 decapsulates IPv6 header (and it works
), and also that tun64 delivers the packet to the server's real interface in IPv4. It's the normal role of a tunnel and that what I'm trying to do, not to deliver a packet addressed to a host to another.
