A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Definitely install fail2ban and use certificates for ssh authentication. Also, use cloudflare and consider using an email delivery service like jetmail instead of sending mail directly from the instance.
You could then block any incoming traffic that doesn't come for port the ssh port or from cloud flare for port 443.
I was using CF initially for proxying, but noticed some weirdness with federation. I would only get updates from Beehaw, but lemmy.world and other servers' updates wouldn't come through. As soon as I dropped the proxy and restarted the server, my instance got flooded by updates. I'm really not sure where to start debugging, so I've kept it off for now
CF has some firewall feature active by default. You have to turn them off.
Checked it out. I ended up having a WAF rule blocking non-US traffic.... Given Beehaw is US based, the fact that I was mostly getting posts from this instance makes a lot of sense now. Thanks again
Glad I could help
