Meh. Safeish. Until one of your servers has a zero day.
Everything has some sort of vulnerability, the qestion is will someone be assed to abuse it.(rheotical question)
Not so much will someone be assed about it, it’s whether a script will pick you up your server. There’s a ton of aggregation search engines that scan most IPv4 addresses and list them on what ports are open etc. such as Shodan.io
Like I said, safeish.
As far as i understood it a cloudflare tunneled service should not be visible when port scanning. Or am i completely wrong here? I started using tunnels just so i can avoid opening ports to the internet. I also restricted the access to my services to specific countries.
The only thing a CF tunnel does is protect your home IP. Doesn’t protect the app or server you’re exposing.
Well it does slightly more than just obfuscating your home IP, in that it will also do automatic bot, DDOS prevention, etc...
Nothing will stop a general scan from happening. Especially if it’s a slow scan.
Scans won’t trigger dos/ddos alerts.
Well yeah, that would get your host IP...if they're doing a general scan of whole ISP IP ranges (Which nothing could really stop, except for a good firewall). But there is much more low-hanging fruit for hackers than to scan tens of thousands of unoccupied subnets.
Ilulz. Automated scans cost nothing in resources. That would not find a host IP, it’d find the public Ip and open port.
I would consider time a pretty major resource....and yes, you are correct I misspoke/typed. I meant public IP, not host IP...
Anyway, the point is not to prevent all attack vectors (which is impossible, unless you're totally offline/air-gapped/etc), OP wants to minimize the probability of infiltration. So to get back to the question, yes CF tunnels help with that when implemented correctly.
tunnels are reverse-portforwarding. ports aren't open on my network but on theirs.
anyways i moved back on VPS because im not 100% sure what is my ISPs stance lmao. and since i cant have much control with my internal network for now, id rather stay away but i def wanna host at home eventually
