If the VPN device that provides your internet access is not capable of using 802.1q frame tags, you will have to use port overlapping to allow both VLANs to use the same device.
Configure all of the other ports as untagged members of their respective VLANs using general mode. You will need to create a separate VLAN for the VPN device. The port connected to the VPN will be untagged on all VLANs and its native VLAN will need to be set to the newly-created VID. All of the ports will need to be untagged on this VLAN as well.
For more information about port overlapping and a basic configuration, see the following thread:
