Done with the Parameters in the Software Release. Allow to redirect an IPv6 port of the host instance to the port of the VPS.
ssh your_username@ipv6_address -p 10022
Here is an example applying the rules to ssh usage. Since port 22 is for ssh, you can access your vps by ssh your_username@ipv6_address -p 10022. According to the previous screenshot, there is "nat-rule-port-tcp-22 2001:67c:1254:64::ea6f : 10022". We can thus:
ssh my_username@2001:67c:1254:64::ea6f -p 10022
