 K900 | So uh | 07:11:28 |
| K900 | Has anyone had a situation where outgoing connections from WSL, specifically over IPv6, get dropped | 07:11:52 |
| K900 | And not like blackholed dropped, but full on RST dropped | 07:12:00 |
| K900 | Exact same machine but no WSL works perfectly | 07:12:18 |
| K900 | OK great | 07:23:11 |
| K900 | It's TCP segmentation being broken | 07:23:17 |
| K900 | * It's TCP segmentation offload being broken | 07:23:20 |
| K900 | Which I assume means hyperv | 07:24:02 |
 nzbr (they/it) | I tried to check, but apparently my WSL just doesn't do IPv6 at all | 07:24:47 |
| nzbr (they/it) | Also why did I only get a notification for the second set of messages but not the first? Gotta love Matrix... | 07:25:40 |
| K900 | ethtool -K eth1 tx-tcp6-segmentation off | 07:26:19 |
| K900 | Just fixed i | 07:26:21 |
| K900 | * Just fixes it | 07:26:22 |
| nzbr (they/it) | Are you in a different network mode than the default? | 07:26:41 |
| K900 | Currently on mirrored but this doesn't seem to matter | 07:26:51 |
| nzbr (they/it) | Ah, I'm on the default one, so that probably explains why there is no IPv5 | 07:27:33 |
| nzbr (they/it) | * Ah, I'm on the default one, so that probably explains why there is no IPv6 | 07:27:35 |
| nzbr (they/it) | (To be clear, the host does have IPv6 and it works just fine) | 07:27:50 |
| K900 | Oh no | 07:29:11 |
| K900 | It's forwarding from the NIC | 07:29:14 |
| K900 | And to the NIC | 07:29:28 |
| K900 | It's not doing its own segmentation in hv_netsvc | 07:29:38 |
| K900 | Tried to update the NIC driver | 08:38:51 |
