No connection on bridge with dhcp


Aug 28, 2018
I have 3 bridges.
vmbr0 - set up on install, directly connected to my PC, soon will be used by pfsense vmachine as LAN and gateway for VMs/CTs
vmbr1 - connected to my network, soon will be used by pfsense vmachine as WAN.
vmbr2 - also connected to my network

What i want is to set vmbr2 as my default gateway, only for proxmox(host) to connect directly to my network. CTs/VMs will be using vmbr0.

I set dhcp and gateway on vmbr2, it gets the IP correctly, but still have no connection. Ping doesnt work.

t@proxmox:~# ping
PING ( 56(84) bytes of data.
From icmp_seq=1 Destination Host Unreachable
From icmp_seq=2 Destination Host Unreachable

An here are my interfaces

auto lo
iface lo inet loopback

iface enp0s7 inet manual

iface enp2s0f0 inet manual

iface enp2s0f1 inet manual

auto vmbr0
iface vmbr0 inet static
        bridge-ports enp0s7
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
        bridge-ports enp2s0f0
        bridge-stp off
        bridge-fd 0

auto vmbr2
iface vmbr2 inet dhcp
        bridge-ports enp2s0f1
        bridge-stp off
        bridge-fd 0

I am almost in the same situation, with 2 physical lan cards and in the need of a cluster, I want to release the 1 LAN for my proxmox to get all updates and the 2nd LAN to use within the VMs.
If there a specifial requirement for the setup please keep me also posted,
Mt network for Proxmox is the, with Gateway, and the up to 240 is my network for VMs.
