Hello again!
Now I have figured out how to solve the issue with no internet from my ProxMox VM, I would like to accomplish something again. Creating VLANS within PFsense.
Currently I have created 2 Linux Bridges again and assigned them to PFsense, and assigned them their VLans only this does not work, I have VLAN Aware turned on, on the interfaces. So how would I accomplish this with ProxMox?
 
If the bridge is VLAN aware, you need to set up VLANs within pfSense, just like you would on a bare-metal instance. The "VLAN" option for the interfaces configured in PVE for your pfSense VM need to be left blank, otherwise *all* outgoing traffic will be tagged with these IDs.

In pfSense you can also configure more than one VLAN per interface, if the bridge is VLAN aware it will be forwarded correctly. Keep in mind that the rest of your Infrastructure needs to support VLAN too, some cheap consumer switches are known to strip VLAN tags from packet headers.

Hello Stefan_R,

Thanks for your reply, I have solved the problem. I had some weird state errors (TCP:SA) in PFsense and when I removed the VM and connected the other VM's directly to a bridged interface it all worked, so I guess I will have to do it from there. Thanks for your reply again! :)
