Proxy: HAProxy 1.6.3 Finally, configure the sites-enabled file with a location block that includes the deny.conf file Fail2ban is writing to. The one thing I didnt really explain is the actionflush line, which is defines in iptables-common.conf. for reference The default action (called action_) is to simply ban the IP address from the port in question.

To get started, we need to adjust the configuration file that fail2ban uses to determine what application logs to monitor and what actions to take when offending entries are found. I know there is already an option to "block common exploirts" but I'm not sure what that actually does, and fail2ban is quite a robust way of dealing with attacks. I also adjusted the failregex in filter.d/npm-docker.conf, here is the file content: Referencing the instructions that @hugalafutro mentions here: I attempted to follow your steps, however had a few issues: The compose file you mention includes a .env file, however you didn't provide the contents of this file.

You may also have to adjust the config of HA. Create a file called "nginx-docker" in /etc/fail2ban/filder.d with the following contents, This will jail all requests that return a 4xx/3xx code on the main ip or a 400 on the specified hosts in the docker (no 300 here because of redirects used to force HTTPS). Since most people don't want to risk running plex/jellyfin via cloudflare tunnels (or cloudflare proxy). However, having a separate instance of fail2ban (either running on the host or on a different container) allows you to monitor all of your containers/servers. Yep.

Multiple applications/containers may need to have fail2ban, but only one instance can run on a system since it is playing with iptables rules. These will be found under the [DEFAULT] section within the file. Setting up fail2ban to monitor Nginx logs is fairly easy using the some of included configuration filters and some we will create ourselves. Web Server: Nginx (Fail2ban). WebApache. Thanks. I already used Cloudflare for DNS management only since my initial registrar had some random limitations of adding subdomains. These items set the general policy and can each be overridden in specific jails. This one mixes too many things together. To change this behavior, use the option forwardfor directive. Sure, thats still risky, allowing iptables access like this is always risky, but thats what needs to be done barring some much more complex setups. I also added a deny rule in nginx conf to deny the Chinese IP and a GeoIP restriction, but I still have these noproxy bans. This results in Fail2ban blocking traffic from the proxy IP address, preventing visitors from accessing the site. Isn't that just directing traffic to the appropriate service, which then handles any authentication and rejection? The steps outlined here make many assumptions about both your operating environment and Comment or remove this line, then restart apache, and mod_cloudflare should be gone. Same for me, would be really great if it could added.

Feel free to adjust the script suffixes to remove language files that your server uses legitimately or to add additional suffixes: Next, create a filter for the [nginx-nohome] jail: Place the following filter information in the file: Finally, we can create the filter for the [nginx-noproxy] jail: This filter definition will match attempts to use your server as a proxy: To implement your configuration changes, youll need to restart the fail2ban service.

This has a pretty simple sequence of events: So naturally, when host 192.0.2.7 says Hey heres a connection from 203.0.11.45, the application knows that 203.0.11.45 is the client, and what it should log, but iptables isnt seeing a connection from 203.0.11.45, its seeing a connection from 192.0.2.7 thats passing it on.
