pve-host can ping gateway, but nothing else.

[Silver_Phone988]

Fresh proxmox 8.3 install, web interface wont respond. So I get on pve-host, I can ping gateway, but google.com doesn't resolve, and I get no response from 1.1.1.1 or other network devices. I have the static ip on 10.0.0.121/24 and the gateway is 10.0.0.1 so I know that a mismatch isn't the issue, and it's a fresh new install so I'm not sure what happened.

/etc/network/interfaces:

auto lo
 iface lo inet loopback
 
 iface eno1 inet manual
 
auto vmbr0
 iface vmbr0 inet static
         address 10.0.0.121/24
         gateway 10.0.0.1
         bridge-ports none
         bridge-stp off
         bridge-fd 0
 iface eno3 inet manual
 
 iface eno4 inet manual
 
 iface eno2 inet manual
 
 iface enp65s0f0 inet manual
 
 iface enp65s0f1 inet manual

So using external ethernet Interface, than you can connect to in Router, that is connected to you world. But remember your network IPs must match.

I’m afraid I don’t understand, do you mean my gateway and machine address need to match up? I don’t really get what you mean by network IPs.

Hi I would need more detail about your network as it seems to be just a setting issue.

What is your subnet ? from your router to your Host
What is the subnet ? where your computer sat
What are your DNS server ?
Are there any firewall on your network ?
Please type route on the PVE to show all known route on the host
