Hi!
I'm going through a strange situation in my infrastructure and I would like to share to understand if anyone has gone through something similar.
I currently have a physical machine with pfSense. This pfSense has 3 ports:
Port A: WAN_1
Port B: WAN_2
Port C: LAN
ISP WAN_1 link is with valid ip.
ISP WAN_2 link is CGNAT.
The LAN port carries the LAN and some VLANs.
The LAN port is being distributed among all nodes of the Proxmox cluster with a simple Port and Forward (unmanaged) switch.
In each VM of Proxmox I insert the TAG of the VLAN created in pfSense and everything works perfectly, I can separate the VMs between the VLANs in a very easy way.
The problem appears when I change the outbound gateway in pfSense...
When the outgoing gateway is WAN_1, everything works perfectly, when it is WAN_2, internet browsing on the VMs is unstable (The VMs are all Windows 10). If I connect a physical machine to the same switch port and forward of the proxmox cluster this problem does not happen.
The only suspicion I have at this moment is because the WAN_2 link is in CGNAT, has anyone faced a similar situation?
Thank you very much!
