Server software firewall cannot help with ddos attacks. Basically if those are indeed ddos attacks you’ll have to look into mitigation solutions which are quite expensive. CloudFlare won’t work as well since they do not support streaming. You should consider getting a server at a data center which provide ddos mitigation, I know that OVH’s mitigation is quite good. בתאריך יום ג׳, 5 ביוני 2018

Alright, I have setup the new rules and am waiting to see if I have any issues. If I do, I will keep working on it. I also read the article below, which mentions exactly what you I was told about 2008 and newer using different ports. https://support.microsoft.com/en-us/kb/929851 Here is the new configuration: root at dc01:~# iptables -S -P INPUT DROP -P FORWARD DROP -P OUTPUT ACCEPT -A INPUT -m

Hi, to prevent scripted dictionary attacks to sshd I applied those iptables rules: -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -m recent --update --seconds 60 --hitcount 4 --name SSH --rsource -j DROP -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -m recent --set --name SSH --rsource And this is part of logwatch: sshd: Authentication Failures: unknown

Hai, Im missing a few things. And maybe time server port to open? Are your dc's time server also? These are the ports i've set. TCP what im having. 22,42,53,88,135,139,389,445,464,636,3268,3269,1024:5000,49612:65535 How you did: 22,53,88,135,139,445,464,636,1024:5000,3268,3269 Your missing 42 389 and range : 49612:65535 UDP what im having. 53,67,68,88,123,137,138,389,464 How you

I just looked up 42 and 68. I do not use WINS or BOOTP. I am removing range 1024-5000 and replacing it with 49612-65535 now. I already allowed 389 TCP.

Hi After several days testing and studing howtos and docu again ... I want to limit all tcp trafic with the limit module to say one connection per second except some known trafic. (This is because of using p2p progs gets mi crazy which gets my adsl modem down and I share my net with some users and because of encryption of stream l7 does not work ...) As I understand the limit module does work

Hello I've got this Mini-PC https://www.zotac.com/product/mini_pcs/zbox-ci323-nano everything is fine -> latest 6.8 kernel works; both Ethernet-Interfaces work and also the WLAN-Interface works; the two Ethernet-Interfaces are eth0 and eth1 the WLAN-Interface is wlan0 eth1 is connected on ISP side eth0 is connected on my LAN side to a switch; and wlan0 shall also be on my LAN side f?r

Hi, I dont think you can deny all ddos against your box, you will need help from your isp. That is because if a person sends you enough packets, like 1mbit (and your line is 1mbit) full of packets, your connection is stuck, whether you filter or not. Though you can mitigate those by closing all non needed ports, log them if any attempt is being made to connect to them, and use a bogon list which

I know someone who for the past 4 days has been having the heck ddosed out of him. He runs a gaming server, and ran a report on the ddos; he has 8 pages of that and a few hours ago there were 16 pages. They''re attacking his machine on random ports and he blocks UDP traffic on those ports, but they keep attacking on other ports. So far he''s banned over 800,000 IP''s.
