Having issues with VLAN connectivity on my Proxmox setup. My Ubuntu VM is getting an IP address, but it cannot reach the internet. I’m trying to figure out if my VLAN config is wrong or if I'm missing a route/gateway somewhere. Also vlan are set in OPNsense.

Here’s my /etc/network/interfaces<config:

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.4.7/24
gateway 192.168.4.5
bridge-ports eno1
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094

auto vmbr0.62
iface vmbr0.62 inet static
address 192.168.62.1/24 # Services VLAN

auto vmbr0.15
iface vmbr0.15 inet static
address 192.168.15.100/24
gateway 192.168.15.1
