Hi,

I have 3 Servers with proxmox installed, in one of them I have PFsense, and in that same server I have more VM, I use the following address:

  • Network for users (10.9.109.X)
  • Network for servers (10.9.110.X)
  • WAN

To extend the networks of users and servers I use a switch. I direct the network through PFSense.
My PC has it in the user segment, and something very peculiar happens, when I want to connect to proxmox through the user interface 10.9.110.1, I cut the communication, and the same thing happens with all the virtual machines that live in that proxmox server, if I connect to another proxmox server that uses the same network address (10.9.110.X) It does not cut me the connection, nor does it do it if I use the user address, that is my proxmox, has double network address:
10.9.110.2 and 10.9.109.2
I do not know why only when I access proxmox from the server interface allows me to establish the connection via console and ssh only for two minutes maximum, then I see that the connection is hanging and lost. I do not know what to do or what to do or where to look, first I thought it was a firewall problem, but it can not be, because it does not cut the connections in the entire network segment 10.9.110.X, but only in one proxmox server
 
I think a quick visual draft of your situation would help here. Also have a look if you have set multiple gateways + check system logs.
