It seems that IPv6 access is available in my router.
Please check your IPv6 source first:
- Make sure IPv6 is enabled on the GL router, and check that the ISP Router/ISP modem (primary connection) supports IPv6 and is enabled.
- Make sure you are using an AirVPN profile include IPv6 source, and the server supported the IPv6.
- After connected, there are both IPv4 and IPv6 addresses, and dual stack is available, as shown in the screenshot above.
