When connected AmneziaVPN is filtering port 53 on my router (192.168.1.1). So obviously DNS resolution should fail, but it doesn't. My AP is providing a separate ipv6 address which has port 53 open and which in turn forwards to 192.168.4.1. AmneziaVPN doesn't filter port 53 on AP's ipv6 address when it probably should as it can lead to leaks.
