  3. Select a tunnel type.
    OptionDescription
    6in4 For IPv6-to-IPv6 communication over an IPv4 backbone. The source and destination IPv4 addresses must be manually configured. This method is recommended for point-to-point communication.
    6to4 For IPv6-to-IPv6 communication over an IPv4 backbone. The destination IPv4 address of the tunnel can be automatically acquired, but the source address must be provided manually. This method is recommended for point-to-multipoint communication.
    6rd For IPv6-to-IPv6 communication over an IPv4 backbone. This tunnel is an extension of the 6to4 tunnel. The tunnel can be established by a provided and predefined ISP prefix.
    4in6 For IPv4-to-IPv4 communication over an IPv6 backbone. The source and destination IPv6 addresses must be manually configured. This method is recommended for point-to-point communication.
  4. Specify settings.
    OptionDescription
    Zone Zone assigned to the tunnel.
    Local endpoint IP address of the local endpoint of the tunnel. For 6in4, 6to4, and 6rd, this is an IPv6 address. For 4in6, this is an IPv4 address.
    Remote endpoint IP address of the remote endpoint of the tunnel. For 6in4, this is an IPv4 address. For 4in6, this is an IPv6 address.
  5. Optional Specify advanced settings.
    OptionDescription
    TTL Time-to-live value for packets. This value defines a limit for the number of attempts to transmit a packet before discarding it.
    TOS Value assigned to an IP packet according to the type of service provided. The service defines the packet priority and routing characteristics (latency, throughput, or reliable service).
