I don't know where my ISP routes the /48 i have a Server in a colocation rack.
All the Info i got is my IPv6 GW and the starting IPv6 Adress and access to a control panel for "RDNs" Entrys.

I've Switched to a /64 for the WAN:
WAN Interface:
Static IPv6: 2a05:bec0:XXX:9::1/64
GW: 2a05:bec0:53::1

LAN: Interface
Static IPv6: 2a05:bec0:XXX:8::1/64
GW: Auto-detect
