Hello, on my PVE server (v. 5.2.7) I have two ethernet interfaces. I decided to dedicate one for Proxmox administration, the other for virtual machines. Both nics are connected to the same network (same switch). I assigned a static ip address to the host dedicated nic, and no ip to the other nic used by virtual machines. This is my configuration: Code: auto lo iface lo inet loopback auto eno2 iface eno2 inet static address 10.0.80.192 netmask 255.0.0.0 gateway 10.0.0.3 iface eno1 inet manual #non utilizzabile iface enp1s0 inet manual #pci-e auto vmbr0 iface vmbr0 inet manual bridge_ports enp1s0 bridge_stp off bridge_fd 0 eno2 is used to administrate Proxmox. vmbr0 is used by VMs. Now, it works all fine, but... I've lost the possibility to configure virtual machine NICs in NAT mode. What can I do?
