[13:04] <PeGaSuS> so, I've made some changes to my netplan configs and I'm having some warnings related to routing. here's the current configs and warnings: https://0bin.xyz/view/8950a048 
[13:05] <PeGaSuS> I really can't fugure it out
[13:11] <danilogondolfo> PeGaSuS, gateway6 is deprecated, you need to use 'routes' instead. There are some examples here https://netplan.io/examples
[13:12] <danilogondolfo> it seems you already uses it in your 99-he-tunnel.yaml
[13:26] <PeGaSuS> my problem is that I can't understan netplan routing in any way, though. I've been having this issue for almost one week and I can't really wrap my head about routing and other options
[13:28] <PeGaSuS> commands like `curl -6 https://nominatim.openstreetmap.org` or even `mtr -6 nominatim.openstreetmap.org` have no response whatsover
[13:43] <PeGaSuS> I've tried this: https://termbin.com/3sp0
[13:44] <PeGaSuS> I cant understand this is no way.. I swear tto god
[13:50] <danilogondolfo> well, maybe if you provide the output of the command below someone might spot something
[13:50] <danilogondolfo> ip addr
[13:50] <danilogondolfo> ip link
[13:50] <danilogondolfo> ping6 nominatim.openstreetmap.org
[13:50] <danilogondolfo> tracepath -6 nominatim.openstreetmap.org
[13:51] <danilogondolfo> and ip route of course 
[13:56] <PeGaSuS> https://0bin.xyz/view/26226a86 > the output for all of those commands. I had to stop tracepath after 25 attempts
[14:02] <danilogondolfo> and 'ip -6 route' as well, ip route will not show ipv6 routes...
[14:05] <PeGaSuS> I think I've broken my machine entirely. can't access it via SSH anymore and it doesn't answer to ping
[14:06] <PeGaSuS> now I need to figure out how to fix it from rescue boot
[14:23] <PeGaSuS> the `ip -6 route` output: https://0bin.xyz/view/27827d76
[14:24] <PeGaSuS> I've merged the tunnel config with the default one: https://0bin.xyz/view/05d9a49a
[14:25] <PeGaSuS> I've tried to follow: https://netplan.io/examples#:~:text=dhcp%2Didentifier%3A%20mac-,Connecting%20an%20IP%20tunnel,-Tunnels%20allow%20an
[14:31] <danilogondolfo> is the tunnel working? can you ping the other side?
[14:32] <PeGaSuS> yes. I can ping the tunnel addresses perfectly from another machine
[14:34] <PeGaSuS> this is an example: https://0bin.xyz/view/b30b0069
[14:36] <danilogondolfo> is the default route itself (2001:470:1f20:a::1) pingable? 
[14:37] <PeGaSuS> I can also ping it from another machine, yes
[14:38] <danilogondolfo> well, it must be reachable from the machine you are working on
[14:38] <PeGaSuS> I can also ping it from the machine with the tunnel
[14:40] <PeGaSuS> fwiw, here's my tunnel: https://imgur.com/ku3EEiM.png
[14:41] <danilogondolfo> ok, at this point you will need to tcpdump the other end and confirm packets are going through
[14:41] <danilogondolfo> you might a routing problem there
[14:42] <danilogondolfo> you might have*
[14:42] <PeGaSuS> in this case it may be HE fault?
[14:43] <danilogondolfo> it's hard to tell, you need to check if the packets are going to the destination but never coming back for example
[14:44] <PeGaSuS> how would I do that?
[14:44] <danilogondolfo> as you can ping your default gw, I'd say the traffic is getting to the other side at least
[14:45] <danilogondolfo> you don't have access to the other end of the tunnel?
[14:46] <danilogondolfo> if you have access to another machine in another network that speaks ipv6 you can try to ping it from this host and check if the icmp packets are getting there
[14:46] <PeGaSuS> I can ping the machine from inside and outside it via IPv6
[14:47] <PeGaSuS> the other end of the tunnel is Hurricane Electric (tunnelbroker.net)
[14:51] <PeGaSuS> I'm applying the tunnel on machine A. I can ping any IPv6 address that I see with `ip a` from inside and outside machine A.
[14:52] <PeGaSuS> I can use `curl -6 address` and `mtr -6 address` with some adresses but not with https://nominatim.openstreetmap.org, for example
[14:53] <PeGaSuS> how can I remove/disable a tunnel completely? 
[14:53] <danilogondolfo> unfortunately I don't have ipv6 here to test it. Is this address pingable from this host? 2001:4860:4860::8888
[14:56] <PeGaSuS> yees. I can ping it from machine A perfectly
[15:00] <danilogondolfo> hmm that's google DNS. So I don't know what's wrong with openstreetmap.org, but your configuration seems to be working fine then
[15:14] <PeGaSuS> I believe that's HE fault since, apparently, openstreetmap.org is hosted by HE
[15:20] <PeGaSuS> hosted or tunneled by HE*
[15:36] <PeGaSuS> if I remove a tunnel from the netplan config, I deconfigure it right? I mean, it's not used anymore, correct?
