IPv6 tunnel

i want to ask some question.
i'm about to make a computer network, where i have public ipv4 address and
i want to put a private (or tunnel) ipv6 address on its interface.
so, i think any ipv4 public network could access my ipv6,
i want to ask, is this possible? if possible, what configuration should i
do?
if not possible, could you give suggestion what method should i use for my
server, i want a private ipv6 server (one interface with public ipv4)
 could be accessed by any outside public ipv4 computer.

thank you for your attention,
