VPN with local Ipv6 address + Policy based routing

[jbattermann]

Good afternoon,

I am trying (and currently still failing) to utilize a VPN for policy based routing to certain target IPv6 networks. The VPN provider defines one static 172.24*/32 and a fd00:*/128 local address for IPv4 and IPv6 respectively that one must use (see this).

I've added two LAN firewall rules to use the corresponding VPN IPv4 and IPv6 gateways for said target networks and for IPv4 it works, for the IPv6 target networks.. it does not. As far as I understand for IPv4 regular NAT is the helping hand here, for IPv6 I am a bit lost, as I have no way of i.e. utilizing NPT as the real LAN side of (IPv6) things cannot be mapped to that one fd00:*/128 address the VPN provider specified.

Does anyone how this could be done?

Thanks,
