NATting OpenVPN -> IPSec

[maxxer]

Hi.
I've an established IPSec tunnel going from our LAN to a remote network.  Then I have an OpenVPN tunnel for accessing our LAN from outside. I need to NAT OpenVPN network to the IPSec tunnel, because I cannot manage the other endpoint to add a new network.

In pfSense I added a second P2 entry with the OpenVPN subnet and I was able to NAT it to the LAN address. In OPNsense I understand I need to use BiNAT, but I must have missed something.

On IPSec I added a manual SPD entry with the OpenVPN net.
In Firewall > NAT > One-to-One I added an entry with OpenVPN NET as External, and firewall's LAN ip as Internal IP. Any as destination.

But this way it's not working. What's wrong?

Thanks
