Checking my comprehension

Good morning all

I have been struggling for the last couple of days with the configuration of my LAN network (based on Unifi gateway UDM PRO SE and several switches) - I have created few LAN networks as listed below / few WIFI

• VLAN 1 = secure network
• VLAN 2 = IOT devices
• VLAN 3 = CCTV
• VLAN 4 = Homelab - my target is to get all my LXCs using 192.168.4.0/24 subnet
• VLAN 99 = Guest

Topology as shown below

I am following some YT videos but i end up with no connection for my two first LXCs

My Unifi firewall configuration

Some info about my Proxmox configuration

• Firewall Promox : OFF both for the node and Datacenter
• etc/network/interfaces file modified (see below)
