Vpn site to site Opnsense - Ubuntu

[sandman]

Sorry if this post is already solved by a FAQ, if so, drop it.

I am trying to set up a site to site vpn between two networks using opnsense and Ubuntu linux as edges of the connection.
The documentation is clear so the opensense side is ready, but what shall i do now on the ubuntu side to connect to the opnsense to estabilish the vpn ?
May i create a config file through opnsense web interface, load it into the linux box and run openvpn with the configuration file switch ?

Thank you very much for your attention.

VPN: OpenVPN: Client Export
is not what you want?

For site to site the client config will hardly do.

But why don't you copy the config file from your OPNsense and reverse the roles before you put it onto your Ubuntu box?

First of all, thank you all for answering me so quickly, I really appreciate.

I already discarded the client config as it didn't solve my issue or i am not enough smart to use it in the right way .
I agree, using a reverse config file is the key, but my new problem is my lack of knowledge about Opnsense and its filesystem tree, where should i search for ithe config file ?

Again thank you in advance for your patience.
