cloudflare ddos protection is cetralization?
Yes, use a competitor at least.
About 20% of global traffic is routed through Cloudflare so unfortunately Cloudflare is very much a massive case of centralization.
A Cloudflare outage would affect a huge number of websites and services and they have some degree of control over the way you host your and use their services.
How long before a website not behind something Cloudflare is considered suspicious or unwanted
Yeah, did people forget the last big Cloudflare outage already? A good chunk of all big services went down simultaneously. Discord, Amazon, Twitter and even the PS and Xbox consoles networks lmao.
I deadass got a cloudflare error after reopening this post:
the people on selfhost would be very upset if they could read this.
if you can provide me a better way to keep my homelab from getting DDoSed every five minutes then by all means, please share it
You don’t need Cloudflare.
That doesn’t help against a SYN flood.
From what I understand elsewhere in the thread, I believe that’s just a matter of router configuration.
@DaPorkchop_@lemmy.ml @memes@lemmy.world Is that an actual issue or a hypothetical one? I’ve never had an attack in 10 years of publicly hosting stuff.
As someone else who used to host via an open port, you get random connections all the time. Almost constantly and the request paths make it obvious they are scanning for vulnerabilities. Via cloud flare the number of those requests is much lower, as they have to know at least the DNS to do so, (and can’t guess it from a presented SSL cert.)
Yeah, I see random https and other connections all the time blindly scanning for vulnerabilities. Not enough to cause any real problems though. One time I publicly exposed redis or rabbitmq (can’t remember which) and didn’t set a password, so someone set a password for me :). That’s about the worst that’s happened to me.
It’s the reason I set up cloudflare in the first place, so yeah. I was getting SYN flood-ed to the point that my router would just crash almost immediately, and after rebooting it the attack would resume after a minute or two.
Get a router that has flood protection? This is like… Extremely basic network protection.
OpenWRT has had configurable syn-flood protection (enabled by default) since like 2010.
Even if the SYN packets were being ignored, the connection would still be unusable if there’s enough incoming traffic for most legitimate packets to get dropped. And as mentioned in other comments, the router in question is a shitty ISP router which can’t be replaced (although I do have a much fancier router with OpenWRT running behind that).
@DaPorkchop_@lemmy.ml @memes@lemmy.world Hm weird, I don’t see why they would spend their resources attacking random people without any kind of demand. Even at work I’ve never seen one happening.
I still believe Cloudflare has most of its customers because of fearmongering tbh.It’s a bit like saying “having a password on your account is fearmongering, why would anyone try to access your data”.
It’s only fearmongering until you get attacked, and it’s already too late when you do. Better to be proactive.
@Alaknar@sopuli.xyz @memes@lemmy.world Being proactive doesn’t mean you have to hide your personal service behind a billion dollar company. That is precisely the kind of overreaction triggered by fearmongering. If you don’t know how to secure access points or harden configurations, no service will be able to do it for you as if by magic. Not to mention your responsibility towards your users, who may not want to be tracked by a third-party company without their knowledge every time they visit your site (or half of the internet by now).
Is you homelab getting ddosed constantly?
I had had it for years and never ever got ddosed.
Are you sure it’s actually ddos and not just the typical bots scanning for vulnerabilities? Which are easy defended for by keeping updated.
It’s weird as a DDOS is not something that’s just happens, it’s a targeted attack. It’s a rare occurrence that someone decided to attack a homelab.
I spent multiple days getting SYN flooded to the point my router would crash and reboot over and over, and it stopped the moment I set up cloudflare and asked my ISP to change my IP. This was the instance which pushed me over the edge, but there had been smaller attacks lasting a few minutes each for years leading up to this.
What kind of router to you have? A good router should not crash from any amount WAN traffic. But yes, if you host anything you will get scanned even harder than usual.
A shitty ISP-supplied modem/router which I have to use :|
Maybe you can enable bridge mode on it? Then you could run something like opnsense behind it.
It’s only got a DMZ mode where I can configure it to forward all incoming traffic to my own router running behind it, but even in that mode it still has to NAT all the packets. IPv6 traffic seems to get forwarded along without much (if any) additional processing, but for hosting stuff publicly I would obviously need to expose IPv4 as well.
Where are you? I bet there’s at least a few local ISPs that would allow you to use a user-supplied router.
There are better ISPs around, but my parents (who are the ones paying for it) don’t want to switch providers because… reasons? At any rate it isn’t happening any time soon, but once I move out I’ll finally be able to switch to Init7 and be done with it all :)
Could you shell out for a decent firewall? It should be able to protect against majority of ddos attacks unless someone is paying for something big.
But it really is fine to use cloudflare if you want the ddos protection. I wouldnt feel bad at all.
If you didn’t piss off one of the big bot groups, then you have likely a configuration issue.
Anubis:3
Just put it behind a wireguard server and don’t expose any ports?
If you absolutely must expose some stuff, get a cheap 3$/mo vps that connects via wireguard to your home and setup a reverse proxy? They almost all come with DDoS protection.
Conservatives will get really upset once they realize you are changing genders
What’s a good VPS provider for privacy enthusiasts?
I use Hetzner. Its fine. Boring/10 would use it again I guess?
How do I stop a DDOS attack of my website without having port 80 or 443 open, so you can access the website?
Don’t expose the website. That’s the point. Only connect remotely via wireguard.
If you must expose the website, I also provided options in my original post.
There is no point in hosting a website if it’s not accessible from the Web.
Again, this thread replying to the original comment is talking about homelabs.
But also, again, this is addressed in the second half of my comment.
I think you misunderstood; if I run a publicly accessible website (like a Lemmy instance), those ports need to be opened.
A cheap VPS hosting
https://anubis.techaro.lol/docs/admin/installation/
as a reverse proxy may work. The VPS will do the work of verifying requests and stopping bad requests from hitting the target resource. Though certainly if the DDoS is a matter of a massive botnet raiding your domain it may not work as well as something like cloudflare
Yes, I’ve addressed this in my original message.
Get yourself a 3$/month VPS, they almost all come with DDoS protection, and reverse proxy from there. Either restrict the ports on your home network to only that IP, or better yet tunnel all the traffic via Wireguard.
Obviously if you’re hosting a large server this is another matter, but nevertheless almost all serious hosting services offer in house DDoS protection.
But the comment I was originally replying to specifically refered to homelabs.

What would be a good resource to, like, relearn modern networking stuff cuz some of these solutions are totally new ideas to me? I was CISCO and A+ certified way back in 2003; but the only thing I ever really used from those classes and training since then was making cables and setting up smaller, simple networks for home or small businesses. I get the sense a fuckton has changed and this exchange made me want to brush up.
A fuckton is an understatement.
I found just doing it the best for me. Start with proxmox hypervisor on some old pc. Start running a bunch of services. Some documentation mentions “heres how you set it up behind a reverse proxy”. “Hmm…whats that” is pretty much how i learned it.
Then compare with people in the homelab communities who are doing differently and find out why.
i dont understand why people hate cloudflare so much. Do they see the cloudflare logo when a server is down and assume its CFs fault?
Host your own cloud worthy anti DDOS solution with fail2ban /s
Honest question, why the /s?
There was a pretty bad CVE a while back I vaguely recall
The fact that a CVE was found doesn’t make it bad
In fact I’d say if it is handled well, fixed in an appropriate way & communicated correctly, having a fixed CVE should be seen as a good thing.
The alternative, lying to yourself and all your users that your code is perfectly sculpted and reviewed by each godly entity, is not the way.
I use Cloudflare Turnstile because hosting without it is just begging for bots to join my service.
Don’t forget your SSL certificate to prevent man-in-the-middle attacks. 🤪
Don’t forget to have the SSL certificate supplied and managed by Cloudflare, of course 🤫
moms 🙄
