I am trying to setup a VPN gateway with the Opnsense and OpenVPN. It runs on TCP on IPv6 and IPv4. Connecting by either IPv4 or IPv6 is working fine. IPv4 Connections to the internet work fine. IPv6 is not working. I did a Packet trace an it seems it is a Problem with the VPN clients IPv6s not answering to NDP Packets.

A clear and concise description of what the bug is, including last known working version (if any).

Tip: to validate your setup was working with the previous version, use opnsense-revert (https://docs.opnsense.org/manual/opnsense_tools.html#opnsense-revert)

To Reproduce

Steps to reproduce the behavior:

  1. Setup OpenVPN on OPNsense like Setup SSL VPN Road Warrior
  2. Add a IPv6 Network
  3. Connect a client an try to reach IPv6 Internet
  4. No Connection possible

Expected behavior

Geting IPv6 internet Acces via VPN.

Relevant log files

Found nothing regarding the lost Packets.
