Opensnitch reminds me of Windows Vista's UAC prompts. It was pretty annoying for most people but I actually liked it. I like things asking me for permission before they do their thing so yeah this will definitely go to every linux install I do in a virtual machine.

To opensnitch devs, I'm really sorry I don't have money but all I can say is thx dudes !

Turns out that AI bot protection isn't even a big problem anymore — residential proxies are, and the really aggressive scraping is hard to detect and block. A bit disappointing then that @cloudflare doesn't seem to have much in store to help against those. An increasing number seems to get past the Managed Challenge easily too, it seems.

And kind of ironic that, with most "normal" ISPs all renting out IP blocks to web scraping companies (residential proxies), VPNs and private relays/anonymizers have become more trustworthy traffic sources for website owners. 🤷🏻‍♂️

Either way, "AI" and scraping are the death of the open internet and free flow of information because it's clogging all the pipes.

Part of a good #network #security plan is having a good #firewall in place. So why is it that I always fail to consider that I don't have the appropriate ports open on the firewall when facing connectivity problems!? 😹
Already had rounds with nodejs hexoio local network browse access. For device preview. The vitness was the #firewall, as usual. Solved.

#Tailscale 's #netfilter mode affects how its #firewall rules interact with network traffic, particularly in relation to NAT. When set to "on," Tailscale creates and enforces its own rules, which can help manage NAT traversal effectively, while "nodivert" mode allows traffic to bypass these rules, potentially complicating NAT handling.
