I'm setting up Tunnelbroker on my Xubuntu machine but keep encountering "Destination unreachable: Address unreachable" errors when trying to reach a public IPv6 address. This is confusing for someone new to Linux. I followed the example config from Tunnelbroker and added it to /etc/netplan/99-he-tunnel.yaml. The network section shows tunnels using IPv6, but I'm only seeing pings to the local host. In the tunnel configuration, I see routes pointing to 192.168.1.1 via IPv4, but not to the public address. I'm wondering if I missed something in the setup and whether I should disable the tunnel instead of just enabling it. I also heard that some websites block Tunnelbroker IPs, so maybe I can turn off the tunnel manually if needed.
