IPv6 with TrueNAS Core 13

[Qiao Wng]

I'm new to TrueNAS and FreeBSD.
I installed TrueNAS in a virtual machine with Proxmox, I made autoconfigure ipv6 enable, with it, I'm able to visit my TrueNAS via ipv6, but TrueNAS itself is not able to make any IPv6 call.

Code:

root@TrueNas[~]# ping6 2606:4700:4700::1111                                     
ping6: UDP connect: No route to host                                            
root@TrueNas[~]#                                                                

There's how to route table looks like.

Code:

root@TrueNas[~]# netstat -rn6

It just recovered, just after toggling several times of autoconfigure ipv6. DON'T understand the root cause.

Well, I don't use Proxmox so while I can't help you there, (Truenas is on bare metal here) I was able to ping6 so I output my routing table in the hope it sheds some light. I do see that my routing table does list a default gateway: "default fe80::4262:xxxx:xxxx:xxxx%igb0 UG igb0" which I don't see in your output. And hopefully someone else here with more experience with Truenas can chime in as well. Can you ping another device in the same network as your NAS, to rule out a default gateway issue?

What's your router and how frequently are router advertisements sent on your LAN?
