This is exactly that I want to do. For few specific IPv4 address (non routable) I want to redirect the IPv4 address to an IPv6 address. 'relayd' seems to be usable for that case. I will try this solution since, after a short look in the man page, it seems possible to relay from an IPv4 address to an IPv6 address. Unfortunately, some IP providers (generally the access provided is free like with the WIFI in the airports) filter even the port 443 if it is not strictly used with the https protocol. Probably using deep packet inspection method.
