Airwall Agent or Airwall Gateway using IPv6 has trouble connecting

If you have Airwall Edge Services that are using only an IPv6 address, they will only be able to connect to Airwall Edge Services that are using IPv4 addresses through a dual stack (IPv4 + IPv6) Airwall Relay. They also need to have relay policy with each other. Dual stack means the relay needs both IPv4 and IPv6 underlay addresses with global Internet connectivity.

Requirement

You must have a dual-stack (IPv4 and IPv6) Internet connection and public IPv4 and IPv6 addresses for your Airwall Relay.

Set up a dual-stack Airwall Relay

  1. Go to or create an Airwall Relay that has a dual-stack Internet connection.
  2. Set up or open an underlay port group on the Airwall Relay.
  3. Add both an IPv4 and an IPv6 address:
    Note: Select static or DHCP for the IP addresses, depending on your internet provider’s configuration.

  4. Make sure the IPv4 and IPv6 devices that you want to communicate have trust between them on an overlay. See Configuring Device Trust.
