Routable != Reachable, which is obvious once you actually setup a firewall once. My IPv6 /48 is entirely routable. The reachable portions are some ports in the list of popular protocols like SSH, HTTPS and similar. The good part is that the entire /48 is reachable from within and simplifies OpenVPN routing a lot compared to IPv4, which requires a bit of outbound NAT hackery so it doesn't have to traverse the firewall three times (OpenVPN->WAN->LAN instead of OpenVPN->LAN)
