Issues with server connected to two VLANS

So I have a linux server on my network, it has serval VLAN ip addresses (it has a IP on VLAN1 and VLAN3) It is only showing up in Firewalla once on VLAN3 in devices. I need to be able to port forward from the internet to both VLANS on different ports (I am running a VPN docker on VLAN3 and a FTP on VLAN1) The VPN docker works with no issue. I can not get anything to forward to VLAN1 because the firewalla does not see the device on that VLAN.

  Would it be possible to configure your Linux VLAN interfaces to have different MAC addresses?  

  Firewalla identify devices using the MAC address, so your device will show only one time.

  Yea you are right, I have been diggin into this. I am trying to figure this out now if there is a way to generate a new MAC with the new VLAN. There is something called MAC VLANS but its a little out of my skill set.

  I will let you know. I might just add another network card.

  Any reason you are using the same PC connecting to two different VLAN's within the same WAN network?  you probably can just have all devices connecting to it via one IP address instead of VLAN with two IP

  I have a server, that is running VMs that belong to another company, I "host" the servers for them to remote into. This requires there network to be seperated from mine. This Linux server is running Unraid, so it hosts alot of stuff from storage to media to VMs.
