The Tunnel configuration offers you 3 buttons to create IPv6 tunnels that can be used over IPv4 networks. Use these options to gain access to the IPv6 Internet using an IPv4 connection.
- 6to4 tunnel
- This button opens the 6to4 tunnel settings.Important: Connections through a 6to4 tunnel work with relays that are selected by the IPv4 Internet provider's backbone. The device administrator has no influence on relay selection. Furthermore, the selected relay can change without the administrator knowing about it. For this reason, connections via a 6to4 tunnels are suitable for test purposes only. In particular, avoid using 6to4-tunnel data connections for productive systems or for the transmission of confidential data.
- 6in4 tunnel
- This button opens the 6in4 tunnel settings.Note: 6in4 tunnels require more administrative effort, but they represent a secure and stable technology for IPv6 Internet access. This option is also suitable for professional use.
- 6rd tunnel
- This button opens the 6rd tunnel settings.Note: 6rd tunneling is suitable for end users and for professional applications because configuration is less complex than with 6in4 tunneling and the technology avoids the security risks of 6to4 tunneling.
