Before you begin, you should have an Ubuntu 14.04 server set up with a non-root account. My switch was from the jlesage fork to yours. So why not make the failregex scan al log files including fallback*.log only for Client.. real_ip_header CF-Connecting-IP; hope this can be useful. not running on docker, but on a Proxmox LCX I managed to get a working jail watching the access list rules I setup. If you wish to apply this to all sections, add it to your default code block. Is there any chance of getting fail2ban baked in to this?

Set up fail2ban on the host running your nginx proxy manager. I agree than Nginx Proxy Manager is one of the potential users of fail2ban. Currently fail2ban doesn't play so well sitting in the host OS and working with a container. I already used Cloudflare for DNS management only since my initial registrar had some random limitations of adding subdomains. Endlessh is a wonderful little app that sits on the default ssh port and drags out random ssh responses until they time out to waste the script kiddie's time and then f2b bans them for a month. Should be usually the case automatically, if you are not using Cloudflare or your service is using custom headers. 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 added an access list in NPM that uses the Cloudflare IPs, but when I added this bit from the next little warning: real_ip_header CF-Connecting-IP;, I got 403 on all requests. Each fail2ban jail operates by checking the logs written by a service for patterns which indicate failed attempts. Thanks. After this fix was implemented, the DoS stayed away for ever. This will let you block connections before they hit your self hosted services.

If you are not using Cloudflare yet, just ignore the cloudflare-apiv4 action.d script and focus only on banning with iptables. Since most people don't want to risk running plex/jellyfin via cloudflare tunnels (or cloudflare proxy). However, there are two other pre-made actions that can be used if you have mail set up. I agree than Nginx Proxy Manager is one of the potential users of fail2ban. My Token and email in the conf are correct, so what then? For reference this is my current config that bans ip on 3 different nginx-proxy-manager installations, I have joined the npm and fail2ban containers into 1 compose now: Apologies if this is offtopic, but if anyone doubts usefulness of adding f2b to npm or whether the method I used is working I'd like to share some statistics from my cloud server with exposed ssh and http(s) ports. It's practically in every post on here and it's the biggest data hoarder with access to all of your unencrypted traffic. actionban = -I f2b- 1 -s -j Having f2b inside the npm container and pre-configured, similiar to the linuxio container, gives end users without experience in building jails and filters an extra layer of security.

Otherwise, anyone that knows your WAN IP, can just directly communicate with your server and bypass Cloudflare. We now have to add the filters for the jails that we have created. +1 for both fail2ban and 2fa support. Or save yourself the headache and use cloudflare to block ips there. Thanks @hugalafutro. Yes, its SSH. This will prevent our changes from being overwritten if a package update provides a new default file: Open the newly copied file so that we can set up our Nginx log monitoring: We should start by evaluating the defaults set within the file to see if they suit our needs. I used to have all these on the same vm and it worked then, later I moved n-p-m to vm where my mail server is, and the vm with nextcloud and ha and other stuff is being tunelled via mullvad and everything still seems to work. Graphs are from LibreNMS. The log shows "failed to execute ban jail" and "error banning" despite the ban actually happening (probably at the cloudflare level.

Have you correctly bind mounted your logs from NPM into the fail2ban container? bleepcoder.com uses publicly licensed GitHub information to provide developers around the world with solutions to their problems. The name is used to name the chain, which is taken from the name of this jail (dovecot), port is taken from the port list, which are symbolic port names from /etc/services, and protocol and chain are taken from the global config, and not overridden for this specific jail. Next, we can copy the apache-badbots.conf file to use with Nginx. If you do not use telegram notifications, you must remove the action Just make sure that the NPM logs hold the real IP address of your visitors. It seemed to work (as in I could see some addresses getting banned), for my configuration, but I'm not technically adept enough to say why it wouldn't for you.

To exclude the complexities of web service setup from the issues of configuring the reverse proxy, I have set up web servers with static content. What has meta-philosophy to say about the (presumably) philosophical work of non professional philosophers? Solution: It's setting custom action to ban and unban and also use Iptables forward from forward to f2b-npm-docker, f2b-emby which is more configuring up docker network, my docker containers are all in forward chain network, you can change FOWARD to DOCKER-USER or INPUT according to your docker-containers network. People really need to learn to do stuff without cloudflare. Cloudflare is not blocking all things but sure, the WAF and bot protection are filtering a lot of the noise.

Your tutorial was great! edit: most of your issues stem from having different paths / container / filter names imho, set it up exactly as I posted as that works to try it out, and then you can start adjusting paths and file locations and container names provided you change them in all relevant places. You could also use the action_mwl action, which does the same thing, but also includes the offending log lines that triggered the ban: Now that you have some of the general fail2ban settings in place, we can concentrate on enabling some Nginx-specific jails that will monitor our web server logs for specific behavior patterns. Your blog post seems exactly what I'm looking for, but I'm not sure what to do about this little piece: If you are using Cloudflare proxy, ensure that your setup only accepts requests coming from the Cloudflare CDN network by whitelisting Cloudflare's IPv4 and IPv6 addresses on your server for TCP/80 (HTTP) and TCP/443 (HTTPS). Once your Nginx server is running and password authentication is enabled, you can go ahead and install fail2ban (we include another repository re-fetch here in case you already had Nginx set up in the previous steps): This will install the software. You can use the action_mw action to ban the client and send an email notification to your configured account with a whois report on the offending address.
