Accessing a subnet on a diffrent VLAN over OpenVPN on macOS?

Networks:

• 10.11.0.0/24 VLAN 0
• 10.11.1.0/24 VLAN 10
• 10.11.2.0/24 VLAN 20

I have a ClearOS router that is attached to the three networks above, and I have OpenVPN running on the router. On my macOS client (Tunnelblick) I'm able to access everything on 10.11.0.0 network. However, I can't access anything on the 10.11.1.0 or 10.11.2.0 networks, and I'm presuming the reason I can't access these networks is because they are on a different VLAN. Tunnelblick is configuring the OpenVPN connection with a tun device.

Is there a way to configure the macOS client so that it can support VLAN tagging over an OpenVPN connection?

Edit: I'm able to ping the router from the macOS client on 10.11.1.1 and 10.11.2.1. I can't ping other hosts on those networks though, so traffic is reaching the router but not passing through it.
