VM not pinging in 1 subnet between nodes

[olegrand1976]

Hello to all,

here is my problem, I currently have 1 cluster of 4 nodes.

The addresses of my proxmox servers are as follows:
192.168.1.207 host1
192.168.1.208 host2
192.168.1.209 host3
192.168.1.210 host4

If I ping them together, no problem.

I have 1 network card on server host2/host3/host4
And 2 network cards on server host1
(see configuration file below)

I have 1 pfsense VM on server host3 configured like this :
WAN 192.168.1.254
LAN 192.168.2.254

To simplify ...

I have a VM on host 1 with IP 192.168.2.2 :
I can't ping 192.168.2.x, it can't reach any other such addresses.

I have a VM on host 3 with IP 192.168.2.3
I can't ping 192.168.2.2 but I ping 192.168.2.254.

I am currently on proxmox 7.1-7 on all my nodes.

Here are the /etc/network/interfaces for each node:

I've been stuck on this for several days, I'll need a little help to understand what I didn't do right or understand in my configuration.


Thanks in advance for your help!

I have 1 pfsense VM on server host3 configured like this :
WAN 192.168.1.254
LAN 192.168.2.254

Is there a reason why you configured it this way?
I would configure WAN as 2.254 and LAN as 1.254

And you cannot ping different subnets anyway, unless you create a route between them.
Also pfSense WAN to LAN will block all traffic by default.
