      Hey all. I was hoping someone could help me understand a couple items in my firewall setup. I am trying to setup one of my VLANs which serves my Home Automation. My HA needs to communicate with my Camera VLAN and my workstation VLAN. I was just wondering based on the screenshot. I have the Source set to HA net in my HA Firewall settings and the destination and ports set to ANY. I was just wondering what would be the difference if I set the Source to ANY in the HA firewall? What am I accomlishing by setting the Source to HA net?

      Also it shows "States" 117/4.37 GiB. What do those two numbers represent?

        @IMV8N It is a subtle difference but HA Net allows that subnet only. Any would allow any custom routed subnet behind HA Net (which has a different IP range and its own router not using NAT). 99% of the time they are functionally identical.

        117 = open states/connections (click on it)
        4.37 G = bytes.

        Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
        When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.
