I noted there is local DHCPv6 support now in newer versions. I wanted to see if there is a 6to4 support being added to support tunnels for ISPs that have not fully gone to IPv6. A lot of new routers support tunnel broker and similar configurations to add in support 6 to 4 tunnels.
Please let me check your 6to4 tunnel requirement. Do you have any specific requirement ?? (Example: 6rd or 6 in4 etc.)
We have only simple IPv6 support and no 4to6 tunnels are supported.
