Destination unreachable: No route

 @saiko:knifepoint.net | In reply to @charles:computer.surgery
i feel like in the past when i try doing it the systemd-networkd way it doesn't work and you need both or something there are two, you need the global option, not the one on the netdev, at least for IPv6 | 00:35:49 |
| hexa | given that you have a default route on your router | 00:35:57 |
 ElvishJerricco | IIRC ipv6 forwarding is weirder than ipv4 forwarding and you have to have both the per-interface and global settings enabled or something | 00:36:01 |
| @saiko:knifepoint.net | (same as you need to turn on conf.all.forwarding and not the interface one, or at least both) | 00:36:13 |
| @saiko:knifepoint.net | yeah | 00:36:17 |
| hexa | the reason why I just don't bother with networkd for forwarding options | 00:36:21 |
| @saiko:knifepoint.net | the global one turns all the interface ones on | 00:36:27 |
| @saiko:knifepoint.net | no, this is a kernel level thing, not networkd | 00:36:33 |
| hexa | fair | 00:36:44 |

Note, unlike IPv4Forwarding=, enabling per-interface IPv6Forwarding= on two or more interfaces DOES NOT make IPv6 packets forwarded within the interfaces. This setting just controls the per-interface sysctl value, and the sysctl value is not directly correlated to whether packets are forwarded. To ensure IPv6 packets forwarded, the global setting in networkd.conf(5) needs to be enabled.
| 00:36:58 |
| ElvishJerricco | from man systemd.network | 00:37:06 |
| ElvishJerricco | but the global setting sounds like it applies by default to all interfaces | 00:37:42 |
| ElvishJerricco | so I dunno why you'd need the per-interface one too | 00:37:50 |
| ElvishJerricco | unless to disable forwarding on that interface rather than enable | 00:38:06 |
 Charles | google.com and codeberg.org also do that | 00:38:20 |
| hexa | does ipv6 work on your router? | 00:38:38 |
| Charles | yeah | 00:38:45 |
| Charles | oh | 00:38:53 |
| Charles | not anymore? | 00:38:55 |
| Charles | at some point it did | 00:39:24 |
| Charles | not sure how this changes anything but i threw dnsmasq in the trash and now it works | 00:44:56 |
| Charles | on the router and on my desktop | 00:45:03 |
| hexa | lol | 00:45:23 |
| hexa | not the root cause, but I'll take it | 00:45:35 |
| hexa | * probably not the root cause, but I'll take it | 00:45:41 |

| hexa | are you posting images? 😄 | 00:51:04 |
