OPNsense ProtonVPN Gateway and Portforwarding

[Vin2]

Hello together,

i try to setup a vpn gateway with ProtonVPN.

I plan to setup the VPN Gateway following this instruction https://thehotelhero.com/opnsense-protonvpn-setup.

But I m wondering if i m still able to portforward to my Nginx reverse Proxy.

I suspect not, since all my traffic would be redirected to Proton and they dont offer Portforwarding.

Does anybody know more about this topic and possibly a solution to it?
