PureVPN dedicated IP

[totoplop]

Hello all !

It's my first post in this forum, so excuse me if a forgot somes informations.

I already have opnsense working fine, using openvpn as server and client - all goods !

As i'm working over 4G with dynamic IP with my backup line, I would like to setup a VPN to get a "static" ip and got incoming port redirection.
To achieve that, I buy a PureVPN account with dedicated IP support.
Unfortunately not compatible with openvpn ...

Only theses protocols are compatible: PPTP, L2TP, SSTP and ikev2 (as client).
Working fine with a standard VPN using these protocols on ubuntu, however I'm not able to get this up with opnsense ...

Could you please help me with that ?

Don't hesitate if some additional info can help !
Thanks
