Greetings,

I am a bit perplexed and have not found anything helpful on the forums or Internet in general.
My current setup is as follows:

FiOS Router/Default Gateway: 172.16.1.1/24
Proxmox (en1>vmbr0): 172.16.1.6/24
pfSense WAN Interface (en2>vmbr1): 172.16.1.2/24
  • pfSense LAN (vmbr2): 10.0.0.0/24
  • pfSense Malware LAN (vmbr3): 10.6.6.0/24
  • pfSense OpenVPN server: 10.10.10.0/24

In my FiOS router I have configured the following routes:
  • 10.0.0.0/24 via 172.16.1.2/24
  • 10.10.10.0/24 via 172.16.1.2/24
In pfSense, the route via 172.16.1.1/24 already exists.

Currently, I am able to ping and connect to resources on both networks.
For example, my laptop 172.16.1.181 is able to ping my Kali VM at 10.0.0.10
And, my Kali VM is able to ping a random set of 172.16.1.x IP addresses

The problem I am having is:
  • My Kali VM -- 10.0.0.10 -- cannot ping Proxmox -- 172.16.1.6/24 -- even though it can ping other 172.16.1.x addresses
  • Proxmox -- 172.16.1.6 -- cannot ping Kali -- 10.0.0.10 -- even though my laptop -- 172.16.1.181 -- can ping Kali
Any insight would be greatly appreciated
