Pfsense does not take the network adapters

[Thorshammer1996]

Good evening,

I have set up a cluster in Proxmox and it works so far. My problem is that the network interfaces are not really working.

As in many other Proxmox installations, I have configured the network interfaces as Linux bridges.

Then I edited the /etc/network/interfaces file and it should actually work.

Unfortunately the Pfsense does not pull the WAN/LAN interface correctly, I just don't know why.


Here is the /etc/network/interfaces:

Spoiler: intefaces

GNU nano 7.2 interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp0s31f6

auto vmbr2

This is the current situation in the Pfsense:



I hope someone can help me further.

With this in mind, have a nice weekend

Kind regards

Hi,
Proxmox can't really set the networking configuration for your vm's. What you have set in the interfaces is the IP of the virtual nic of the host system (proxmox) in the vmbr, not the address that your vm is gonna have. You can imagine a vmbr device as a software switch and same as a hardware switch, the switch doesn't determine the addresses of it's connected devices.
Pfsense tries to automagically detect which interface is to the wan side and which to lan, but this process is just a guess.
For the eventuality that this fails, you can use option 2, as seen in the screenshot, and configure the interfaces manually.

If I have misinterpreted your problem please describe what is not working
