I purchased a firewall appliance with 4 ports and installed opnsense on it. Best decision of my self-hosted life.
Get one with two 10gbps ports and you are set. Passive cooled, small factor, Intel atom CPU. 4gb ram is plentiful.
On aliexpress can be found for 100€ or little more.
Even much better than an OpenWRT, which I love and use but delegate to internal network (WiFi access points) rather than perimetral defense.
Hi!
I remember I had issues in setting it up. IIRC there was a problem with a too long URL that you where supposed to copy & paste in the browser… And I took me a few tries until I figured that out.
Beside this, I don’t remember if that was the same issue…
Maybe you can post the full trace (with redacted credentials)?
You can pm me of course
