6in4 tunnel with /48 prefix + OpenVPN over ipv6 on Synology NAS

[pkoci]

Hi,

Did anyone successfully run openVPN server with ipv6 enabled on Synology NAS? You basically need to enable DHCPv6-pd in the ipv6 network settings and then enable ipv6 in the openvpn settings. Unfortunately, the prefix selection is empty in the VPN settings. Also, nothing is filled in the ipv6 settings after enabling DPHCP-pd (ipv6 address, prefix length, DNS, etc.).

My router is Asus rt-ax56u with merlin firmware.

Any ideas?
