OPNsense + Tailscale + MullvadVPN

[guest36905]

Hello everyone, I'm new to OPNsense. I tried to read something online for my problem but I could grasp that much.

I have a proxmox instance in which I virtualize OPNsense as my router and an ubuntu server vm where I self host some services. Both OPNsense and ubuntu server has tailscale installed and I can access them by reverse proxying the tailscale IP. So far everything works and I'm able to access them form everywhere.

Now, I have a Mullvad VPN subscription and I would like to route all my WAN traffic through it so that every device (including VMs in proxmox, laptops, phones, etc) I connect to my tailscale network are automatically covered by mullvad.

Is this doable?

Thank you in advance.
