I have installed Proxmox on a virtual machine and am attempting nesting (vm within the vm) but am having some issues getting the network to work correctly. Due to the host having MAC filtering I am trying to use the main Proxmox IP 107.189.30.xxx as the gateway IP for virtual machines. .1 is the gateway for each /24 IP block.
When it's working the following is returned:
arp
But then about 10 minutes later it comes and goes. The following is returned.
arp
It also swaps to the following (outbound works but no inbound during this)
arp
/etc/network/interfaces
/etc/network/interfaces (Proxmox node)
What could be the cause of this?
