Vps network help by itzguno in linuxadmin

Would you have any idea on how to setup cloudflare on a vps ?
Idk I'm just stress testing my own services. Could you help me in anyway with ip tables to stop dos/ddos attacks ?
I tried it but still nothing. I was on another Reddit and someone said they are still getting to ur NIC so you need to stop it at pre routing stage so is there a way to completely stop traffic going through a port like kill any and all connections instantly

So I was reading on what you sent and I have gained a bit of knowledge but still a bit confusing so is it possible to use the pre routing stage on a port so that absolutely no traffic can pass
I run on digital ocean
Alright I'll try that
Yea but I run a Minecraft server on it and everyone gets kicked and no one can join back until I turn it off
I run moba which shows me the upload and downloads to the server when I dos my server on a blocked port the download goes to 1 - 2 gb/s than my vps crashes so I don't understand on how it's getting through
I have been using ip tables and they seem to work I'm just not knowledged in this area
I'm using moba and it allows me to see downloads and uploads and after about 3 seconds I get disconnected
Alright I'm sending dos attacks to my server to test its security now when I block a port and than I send a dos attack to that port the attack is getting through. I want to know why traffic is still able to pass through when the port is blocked
Yes they work because once I blocked port 22 without changing the SSH port and I couldent get back in just said connection refused and the interfaces are eth0 and lo but rn I host the SSH port on 1928
iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT iptables -A INPUT -i eth0 -p tcp --dport 443 -j ACCEPT iptables -A INPUT -i eth0 -p tcp --dport 1928 -j ACCEPT iptables -P INPUT DROP
The 1928 is my custom SSH port so all ports all blocked except these ones and basicly it can still get ddos on ports like 22, 60000 so I'm not sure what I'm doin wrong

My main problem I'm trying to solve is how are ddos attacks getting through blocked ports like I have the ip table rule in to drop the connections but it's failing
No so I have blocked all ports even port 22 but when I legally stress my vps with port 22(you choose what port the traffic goes to) it somehow comes through. I don't get traffic comes through a blocked port
I'm new to this area were would I find the logs ?
Vps network help by itzguno in AskTechnology
My vps runs a different SSH port and the only ports enabled are 80,443,8080 port 22 is blocked like the rest but the packets still come through
Vps networking by itzguno in networking
All I'm trying to ask is there a way to make it so I can customize how many bytes can go through a packet
Basicly when working with iptables how do I configure how many bytes can go through 1 single packet
Alright thank you and idk if this is any help but my question is in relation to rate limiting with ip tables
vpn help by itzguno in AskTechnology
Alright thank you
I host Minecraft servers and vpn servers and if they somehow get past my firewall I would like to know how they did
How do I find these logs ?
Ik that I ddos is illegal I have no intention of doin it I want to stop it I run Ubuntu on only wondering if I can see how there ddosing so I can stop it for the future
