The firewall distro that i am using into this enviroment do not allow two openvpn servers. Or better: maybe is allowed, i’m still not sure about that, but it’s quite far from the webgui level of access.
Maybe i also misunderstood you, it’s always possibile when the language is often used, but not the natural one for who’s writing. 
Anyway, thanks for your time, maybe this solution could help someone with the same kind of issue
