I just got a new dedicated server. They do filter MAC addresses, so I was advised to put proxmox into bridge mode. I have 3 public IP addresses all on the same subnet. I have tried everything but can't get any of the VM guests to be able to access the network. Ideally I want all the systems to go through pfSense, and management would be through a VPN. Here is my proxmox /etc/network/interfaces config Code: auto lo iface lo inet loopback auto eno1 iface eno1 inet static address 38.xxx.xxx.39 netmask 255.255.255.0 gateway 38.xxx.xxx.1 post-up echo 1 > /proc/sys/net/ipv4/ip_forward post-up echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp auto vmbr0 iface vmbr0 inet static address 38.xxx.xxx.52 netmask 255.255.255.0 bridge_ports none bridge_stp off bridge_fd 0 #pfSense WAN auto vmbr1 iface vmbr1 inet manual bridge_ports none bridge_stp off bridge_fd 0 #pfSense LAN I believe I know the correct MAC address of the interface. It's listed in the supermicro IPMI as System LAN1 MAC address. I've copied that address to proxmox / 100 / network device (net 0) Any help would be very much appreciated.
