SOLVED Cannot resolve hosts

[William Ableson]

My TrueNAS is running in a VM on Proxmox. It wasn't having any issue. Recently, while I can access it locally using username@10.0.0.145, I cannot access it externally using DuckDNS. I tried to see if it can access the web from TruieNAS and that also failed.

Code:

ping: cannot resolve google.com: Host name lookup failure

My /etc/resolv.conf is :

Code:

# Generated by resolvconf
search local
nameserver 10.0.0.145
nameserver 8.8.8.8
nameserver 1.1.1.1

No VM settings were changed, so I think it must be something with TrueNAS.

Any ideas on how to fix this?

Did you intend to point the TrueNAS VM to itself as a DNS server? Where's the DNS server for your network?

I use ipconfig /all on my windows box to check DNS and tried those addresses too. No dice. Also, I removed 10.0.0.145 and it had no effect.

Do you have a default gateway defined in your TrueNAS VM?

Do you mean this?

Indeed he does not have a default gateway defined.

Fill the IPv4 Default Gateway with your router address. (maybe 10.0.0.1 or something like that)

Thanks @sretalla , problemed solved! I am not sure how this got reset. I don't believe I changed it, and TrueNAS was accessible from the off local network via SSH and could access the internet too.
