Having an issue getting internet access to devices on a VLAN. Looked at a few different tutorials and followed along and as far as I can tell i mostly just need a VLAN aware bridge and a sub-interface, but nothing i try seems to work. Trying to get a working VLAN 5.

I have the main interface and a sub-interface set up. I've tried both just the network and also an address (172.16.5.0 vs. 172.16.5.1) and neither work.

r/Proxmox - VLAN Config Help

My main interface is showing up as VLAN aware

r/Proxmox - VLAN Config Help

Config from the hardware section of the VM shows it is using VLAN tag 5. However, no internet access makes it to the VM.

So i guess my question is, am i missing something obvious or is this one of those "you don't know what you don't know" moments?
