If I search for ClearOS I find mostly 2+ year old threads. Many older. Many talking about how it has been defunct for years… however if I just visit the site it seems to be still in development and up to date. It also seems like something selfhosted users would like… however I couldn’t find any recent discussions on it to see if its garbage or not.
I plan on installing it tomorrow to check it out. I’ve been trying to migrate away from pfSense but I’ve been having a hell of a time finding a viable alternative and came across some very old ClearOS threads which is how it got on my radar.
I’ve been trying to get an OpnSense install up and running but I just can’t get it working in the most basic installation. My original plan was just to migrate directly to OpnSense but I’ve pretty much given up on it.
I think the problem with Clear OS is that it has a very narrow market. People comfortable with Linux and containers have their own preferred method. And band new users don’t know it exists.
As for your OPNsense issue, I have never seen anything like that before and can not understand it. Hardware conflict perhaps? You can also try OpenWRT or there is a free Sophos firewall. Also Firewalla, but it is a bit old…
