Hello, I'm setting up my fritzbox to tunnel on my fixed ip connection, but it seems that the fritzbox needs a heartbeat anyway. I requested a static tunnel. Is it possible to change my tunnel towards a heartbeat type? Message fritzbox: IPv6 (SixXS Tunnel) Internet connection failed: Heartbeat support required (<message>). This error message informs you that not all configuration steps for the given SixXS connection have been completed. Please contact the SixXS provider to do so now. My tunnel details: Tunnel Id : T86570 PoP Name : beanr01 (be.edpnet [AS9031]) TIC Server : tic.sixxs.net (which is the default in AICCU) Your Location : Sinaai-Waas, be SixXS IPv6 : 2a02:578:3fe:33::1/64 Your IPv6 : 2a02:578:3fe:33::2/64 SixXS IPv4 : 213.219.173.138 Tunnel Type : Static (Proto-41) Your IPv4 : 213.219.157.47 Many thanks!
