I created a VLAN 10 in Proxmox and have VM's on it, and I can not SSH to them.

I have two nodes. I have the issue with VM's on both nodes.
I have both nodes on a LACP LAGG to a Unifi Switch.
Using OPNSense, believe to have firewall Open.
Using 192.168.1.1/24 and 192.168.10.1/24 as VLAN10


Listing Troubleshooting steps.
  • VM's have internet access and are working fine generally
  • Console works, but not SSH.
  • Can SSH to VM's on native untagged network from local windows using anything (putty, WSL, terminal) 192.168
  • Can NOT SSH to VM's on VLAN 10 from local windows using anything
  • From a Ubuntu VM on VLAN 10, can SSH to other node VM on VLAN10 ie VM1101 to VM1102
  • Proxmox Datacenter Firewall Off
  • Proxmox Node Firewall Off
  • UFW Status = Disabled
  • Can not PING from non-vlan VM to VLAN 10 VM
  • I am wondering if I set up VLANS wrong. All I did was select "VLAN AWARE" and then added the network to the VM.
  • From VM on VLAN 10, I can do a traceroute that hits the VLAN gateway and then my ISP
  • From VM on VLAN 10, I can do a ping to gateway 192.168.10.1
  • From VM on VLAN 10, I can do a ping to firewall 192.168.1.3
  • From VM on VLAN 10, I can do a ping to pihole and BIND9 VM
  • I can NOT ping gateway 192.168.10.1 from a different VM NOT on VLAN 10


Here is ` /etc/network/interfaces,`

Code:
auto bond0
iface bond0 inet manual
        bond-slaves eno1 eno2
        bond-miimon 100
        bond-mode 802.3ad

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.80/24
        gateway 192.168.1.3
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

I am a NOOB with 4 years of failure under my belt, ELI5 and be nice, thank you so much in advance. :)
