I tried adding an block all protocols from my other VLANS to the LAN rule set ahead of the allow LAN to any rule, and I still get the same behavior.
Hello all,Just getting started with OPNsense and trying to make sense of something I am seeing. I am sure this is just a misunderstanding on my part, but I would like to make sure I do not have something set up wrong.My setup has LAN (192.168.10.*), GUEST (192.168.20.*), IoT (192.168.30.*), and NoT_CAM (192.168.40.*) networks set up with nothing other than the automatically generated rules and the allow LAN to any rules on the LAN network.Using IoT as an example (all non-LAN networks have this behavior, though), If I first ping from IoT to LAN, I get no return, as would be expected. If I then ping from LAN to IoT I get responses, also as expected. Now, if I immediately go back to IoT and ping LAN I get responses. This is what I was not expecting to happen. If I let the connection sit idle for about 30 seconds, and try the ping from IoT to LAN again, I get no responses.So, I think this has to do with the stateful nature of the firewall, but I am not sure. Could someone please clarify what is going on here? Also, is there any way to keep this from happening?Thanks in advance for helping out a newbie.
I wonder if it is possible to get this information to the developers as it seems like a bug or security hole
