I absolutely love OPNsense, and it’s the perfect place to tinker with my home network, learn more, and do some pretty cool stuff in general. Yet every now and again, something happens that leaves me scratching my head trying to figure out what’s going on. This isn’t an OPNsense quirk before people tell me that I should have used pfSense instead; no, this is a security-by-default quirk, and it affects pfSense, too.
