Title: ProxMox - Opnsense
Post by: nadrias on February 21, 2018, 05:10:29 pm

Hi guys !


j'ai un serveur proxmox avec une Ip failover 10.x.x.26 (example) avec une mac 56:65:34:54:E5:F0

2 interfaces on proxmox : On Lan enp0s20f1 And One Wan enp0s20f2(ip failover)
and bridge : VMBR1, VMBR2

so i créate 2 interfaces on my VM opnsense FW
one virt bridged on VMBR1 where i assing my mac adress from OVH (Wan)
one other virt VMBR2 (LAN)

i config my gateway etc ...

my problem : i can join my firewall on LAN but I can't go to internet so i suppose it come from my wan config


config on proxmox :

Code: [Select]

auto enp0s20f0
iface enp0s20f0 inet manual

auto enp0s20f1
iface enp0s20f0 inet manual

auto enp0s20f2
iface enp0s20f0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 10.54.324.12 (false)
    netmask 255.255.255.0
    gateway 10.54.324.1
    bridge port enp0s20f0

auto vmbr1
   iface vmbr1 inet manual
   bridge port enp0s20f1

auto vmbr2
   iface vmbr2 inet manual
   bridge port enp0s20f2

my config on vm dhcp for lan address and static for wan so i configure the static that

Code: [Select]

auto eth0
iface eth0 inet static
    address 10.54.356.12 (false)
    netmask 255.255.255.0
    gateway 10.54.356.1

I am also having this issue. My VM guests connected to my OPNsense VM cannot reach the internet. I am able to reach the OPNsense web GUI. If someone could post their /etc/network/interfaces config that has successfully gotten OPNsense to work on Proxmox, I would be most appreciative.

I’m in the same situation. The VMs connected to my virtualized OPNsense LAN can get to the OPNsense webgui and ping external ip addresses, but they cannot resolve webpages. I know this is a DNS issue, but I haven’t been able to figure it out.

Did you tried to set promiscuous mode on the bridges that OPNsense is connected to?

Code: [Select]

ip link set vmbr0 promisc on
change 'vmbr0' with yours...
