Support to fwknop port knocking

[hakuna]

I did the upgrade last night to OPNsense 26.1_4 and everything went smooth.
Tonight I did the firewall rules upgrade and like many posts I was like "where are the rules??" after importing it over and over with no progress or anything really \o/


THE GOAL:
The above was necessary to do things right, once!
I do have WireGuard VPN, scanning access from my phone returns nothing and the firewall live log does show Default deny / state violation rule.

I wanna spice the relationship a bit and set the port knocking but....
I cannot find any os-fwknop plugin (or fwknop like openwrt), online forums didn't help much, the official documentation has zero mention of "port knocking" - https://docs.opnsense.org/index.html

Doesn't OPNSense support fwknop instead of the legacy way opening two more ports (assuming that works)???
I don't wanna do the weaker legacy way.

Thank you
