Hello Everyone I am trying to setup VLAN configuration for my proxmox server and I was not able to resolve it can someone please help me with it.

Below is the proxmox network configuration file "/etc/network/interfaces"

Code:
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

When I add clan tag to the interface of VM the vm is unable to connect to the network. I am able to ping the VLAN DHCP server (PFSense) from the VM. Can someone please help me with this.
 
I am using a ubiquity switch and i have already configured it. I am able to test out the VLAN connections from other systems. For creating the VLANs i am using the pfsense on a separate host.
 
I am not specifically opening any ports in proxmox or on switch. I am just using default configurations. Is there any way for me to check if the packets are getting passed using proper VLAN ID?
