OPNWAF/Web Application Business limit simultaneous connections of an IP as NGINX

[Wuensch-AG-Adm]

Dear Opnsense Community,

Is there a way, as with NGINX and Naxsi, with the OPNWAF Web Application Business plugin to limit the simultaneous connections of an IP for the proxied applications?
As it's a well-knows needed security feature of the web application proxies. It's possible that is in the plugin present, but I've found nothing. Maybe it's possible on another layer of the OPNsense Firewall or in another plugin.

Thank you ahead,

Regards,

Joel.
