i need a modification for the opnsense Firewall to enable Portknocking. Allow access the client application try to connect to port 333. it gets rejected by the firewall. the client application try to connect to port 22. we forward it to the ssh server. we only forward one packet with state new to port 22. (after that port 22 state new is locked again for this IP) all packets with state established related are anyway forwarded. denie access if a IP trys to connect to any other port than 22,333. the ip becomes ignored for 5 Minutes. in other words. our application must try to connect to port 333. connect to port 22. all other connections are rejected.

Good day! I can configure Port Knocking on OpenSense for You confidently and quickly because I am a certified network engineer (MTCIPv6E/MTCTCE/MTCNA) having over 10 years of experience in configuring, maintaining and troubleshooting of enterprise network devices, firewalls, and Linux servers. Also, I did it before on MikroTik (RouterOS), IPTables (Debian 10), and pfSense.
