      Hello,

      I have decided to bite the bullet and move our home network to Proxmox to save on electricity. I apologize if this question is a bit stupid, but I'm 76 and not so quick as I used to be. I have a 6-port server, previously only used as firewall but now with Proxmox on it. I have added pfSense, and I was able to get it up and running using the Virtualizing with Proxmox VE Configuration Recipe.

      Now, I want to backup the Proxmox node to our NAS, and this is where things are getting a bit strange for me. This is a trial setup. I know the setup is not secure and I have to harden it but I want to solve the backup problem first.

      The config I used before I started "troubleshooting" is at the end of this post. I configured the IP's in pfSense> The WAN (vmbr1, iface enps1s0 needs VLAN10, connects over a PPoE connection and is not in scope}. The LAN-server segment is 10.14.6.0/24 with 10.10.6.1 as default gateway. I have created a dedicated Proxmox segment 10.10.7.0/24 with 10.14.7.1 as gateway. the Proxmox node is .249.

      In pfSense and just for troubleshooting, I've created a top rule on the LAN segment that allows all communication to the Proxmox segment and on the Proxmox segment a rule that allows all communication to the LAN segment. I also created a rule on the Proxmox segment to allow access to the internet.

      In the current config, I can:

      • access the internet from the Proxmox-node and do the updates
      • ping the gateway on the LAN 10.14.6.1
      • access the proxmox node over SSH and HTTPS from the LAN and ping the proxmox host from the LAN

      In the current config, I cannot:

      • ping or access any other IP on the LAN, where my NAS is.

      The servers on the LAN network can ping each other, so it is not a problem with a host based firewall.

      I have checked and double checked "Block private networks and loopback addresses" and "Block bogon networks" are disabled on both interfaces.

      What should I do to enable communication between the Proxmox node and the servers on the LAN please? The servers on the LAN network can ping each other.

      Thanks.
