요오드 DNS 터널을 통해 연결하고 네트워크 제한을 우회
PassTunnel enables you to bypass network restrictions in some regions and stay connected through a DNS tunnel. It is based on the open source Iodine project. This is not a normal VPN app. And it is slower than normal VPNs. Therefore, users that have unrestricted internet connections are advised to use other VPN apps for a better experience.
