Port mirroring for Dark Trace

[g33kphr33k]

Hi All

I'm new to OPNSense and have bought a DEC3840 to use on a small site. We have DarkTrace Cyber Security Probe which needs to mirror the LAN port on the router. On the Draytek that I am removing we can simply enable Port Mirroring in Promiscuous mode but I do not see such an option here.

Would anyone happen to know how to enable the port mirror function before I raise it with Business Support?

Thank you.
