Working with WEBconfig

To set up a 6to4 tunnel with WEBconfig, proceed as follows:
  1. Type into your browser's address bar the address of the device to be set up with a 6to4 tunnel.
  2. Change to the directory LCOS Menu Tree > Setup > IPv6 > Tunnel > 6to4 and click on Add.
  3. Enter a name for the remote peer, e. g. "TUNNEL-6TO4".
  4. Leave the Routing tag unchanged as the default value "0".
  5. As the Gateway address you can accept the default value "192.88.99.1". This is the default anycast address for 6to4 relays that your device connects to.
    This address is the reason why 6to4 tunnels are unstable and insecure. There is no assurance that a 6to4 relay will be available, and publicly available 6to4 relays may not be trustworthy. There is no guarantee that the relay does not record your traffic.
  6. In the field IPv4-Rtg-tag accept the default value "0"
  7. Enable the firewall for this tunnel.
    If you disable the global firewall, you should also disable the firewall for the tunnel.
  8. Save your entries with Send.
  9. Change to the directory LCOS Menu Tree > Setup > IPv6 > Router-Advertisement, open the Prefix options table and click on Add.
  10. Enter a name for the interface that uses the 6to4 tunnel, e. g. "INTRANET".
  11. Set the value for the Prefix to "::/64" in order to accept the prefix issued by the provider automatically and in its entirety.
  12. Accept the default value of "1" for the Subnet ID.
  13. Set PD source to the name of the remote peer that you previously defined in the example above, e.g. "TUNNEL-6TO4".
  14. Save your entries with Send.
  15. Change to the directory LCOS Menu Tree > Setup > IPv6 > Router-Advertisement, open the Interface options table and click on Add.
  16. Accept all other default values ​​without change.
  17. Save your entries with Send.
  18. Change to the directory LCOS Menu Tree > Setup > IPv6, open the Routing table and click on Add.
  19. Set the Prefix to the value "::/0".
  20. In the field Rtg-tag accept the default value "0".
  21. In the field Peer or IPv6, enter the name of the interface that will use the 6to4 tunnel, e.g. "TUNNEL-6TO4" in the example above.
  22. Enter a descriptive Comment for this entry.
  23. Save your entries with Send.
  24. Enable the IPv6 stack under LCOS Menu Tree > Setup > IPv6 by setting the option Operating to "yes" and save with Send.
