Trying to ping out from Proxmox CLI. Destination unreachable.
In my fault finding I tried the following-:
ip neigh
Returns message "192.168.1.1 dev vmbr0 FAILED".
You gave us zero information about your setup. The more details you post here, the greater the chance for a helpful answer
Please start by giving us some information, like the copy-n-pasted output of some commands, run on a PVE host (either via SSH or via "Datacenter --> <one Node> --> Shell", both ways allow copy-n-paste):
PVE System information:
pveversion -v
Basic network information:
ip address show # currently active IP addresses on one NODE
ip route show # currently active routing table on one NODE
ip link show # currently active links on one NODE
cat /etc/network/interfaces # configuration of the network and/or ifquery -a for comparison from one NODE
ping -c 1 -W 1 9.9.9.9 # a simple "ping" to verify outgoing routing
Those are examples. You may add/edit commands and options if you can enrich the information given. Oh, and please put each command in a separate [CODE]...[/CODE]-block for better readability.
