ZTE MF275R - Can it work with VPN?

[wireless]

I recently switched from my previous ISP to a ZTE MF275R LTE Smart Hub provided by TELUS. Since then, I have been unable to use VPN (PPTP) to reach my work machine from home (Smart Hub is at home). I'm using the Windows 10 built-in VPN connection, which previously worked (with my past ISP), and no longer does, saying that it's likely that one or more devices on my network is not supporting Generic Routing Encapsulated (GRE) packets.

Is there something I have to configure in the hub to allow VPN to work? Or does it not allow VPN at all?

Thanks in advance!
