I am just getting started with Opnsense and want to better understand Firewall rules.
My web server listens on port 8019 and appears to be accessible from the internet at all times.
Not sure what rule is allowing this to happen. My web server is on my IoT_LAN using 192.168.1.xxx.
My first notice of this issue was when I configured a port forward rule that would allow the web server to be accessed via port 8019. That worked fine, it was when I tested this port forward by disabling it is when I noticed the web server is still accessible from the internet.
What rule is allowing port 8019 to the web server and how do I fix that?
Guessing you didn't "Apply" after disabling the port forward.....
