Hello, was wondering if anyone has such a setup and can provide some help

I have my backup pfsense as a VM via Proxmox and when I ssh into the mgmt IP 10.200.1.81 from vlan 100 192.168.2.4 (my desktop) then the SSH connection drops after 30 to 40 seconds. But if i ssh to the vlan 100 interface 192.168.2.81 then ssh connection fine.

I also made sure that hardware checksum option is disabled

I created 3 Linux Bridge connections in PVE as per below and enabled VLAN aware. vmbr0 is the dedicated IP for PVE.

Then for the pfSense VM, i did this; I add the 3 Linux Bridge cards (WAN, LAN, SYNC interface for CARP) On the unifi switch side these 3 ports are set to default untagged network. I also made sure that hardware checksum option is disabled on this router.

But I am still having the dropping SSH issue when i connect from VLAN100 192.168.2.1/24 over to the MGMT interface on pfsense (10.200.1.1/24) and again if i SHH into the VLAN100 interface of pf then no drops.

Just tested something.. So this issue only occurs on the router that is in BACKUP Carp status. As soon as i cut it over to Master then SSH remains up.

So it seems like i cannot ssh via inter-vlan to the pfsense that is marked as BACKUP.

You likely have a loop. Check your STP/RSTP/MSTP logs on your Unifi switch.

vmbr0, vmbr1, vmbr2, vmbr3 and anything connected to them are all on VLAN 1. Each of those should be on their own VLAN.
