AlwaysOnVPN and IPv6 (DS-Lite)

Good day,

we deployed AlwaysOnVPN Server with a public IPv4 address. The first tests run quite well.

Now we have the first user with a DS-Lite connection (1000 Mbit/s). He has IPv6 addresses and apparently a shared public IPv4 address.

After some reading in the forums of the users ISP (Vodafone / Kabel Deutschland Germany) this is causing problems. We can confirm that! (Massive connection problems).

We are now in the process to get a IPv6 Subnet (/60) from our Headquarter provider.

Is it enough to make our AlwaysOnVPN-Server reachable through IPv6? The "internal" interface will still be IPv4.

Can anyone share some experience or give us some hints/tips how our setup should look like for this usecase?

Thanks in advance

Best regards
