Hi Jeremy, When you create a zone, in the pod setting, you need to input the system Ip ranges. The private IPs of system vms are picked up from the range.
Reserved system gateway Reserved system netmask Start Reserved system IP End Reserved system IP Please make sure you have input correct values. -Wei On Mon, 28 Feb 2022 at 12:31, Jeremy Hansen <jer...@skidrow.la.invalid> wrote: > For example, my secondary storage vm has this assigned: > > > - IP Address > 192.168.30.62 > - Private IP Address > 192.168.30.55 > > > The public IP is predictable because I see this in the config for public > IP addresses under Network, but the private IP changes each time the vm > reboots.
