I run OPNsense pretty much stock + unbound + adguard home. Does anyone have a security hardening guide? I feel like I must be missing a few key things to make it self-hosted ready?



As you can imagine its pretty "Hard" by default...

but you should make sure you didn't turn dumb things on like WebUI/SSH acces from WAN etc..

this is a good thread on the subject https://forum.opnsense.org/index.php?topic=22117.0
